This document will guide you through the process of Countly SDK installation and it applies to version 22.06.X
Countly is an open source SDK, you can take a look at our SDK code in the Github repo
Click here, to access the documentation for older SDK versions.
This is the Countly SDK for React Native applications. It features bridging, meaning it includes all the functionalities that Android and iOS SDKs provide rather than having those functionalities as React Native code.
Supported Platforms: Countly SDK supports iOS and Android.
You can take a look at our sample application in the Github repo. It shows, how most of the functionalities can be used.
Adding the SDK to the project
In order to use the React Native SDK, please use the following commands to create a new React Native application.
npm install -g react-native-cli # Install React Native
react-native init AwesomeProject # Create a new project
cd AwesomeProject # Go to that directory
react-native run-android # OR # Run the android project
react-native run-ios # Run the iOS project
# New terminal
adb reverse tcp:8081 tcp:8081 # Link Android port
npm start # Run the build server
Run the following snippet in the root directory of your React Native project to install the npm dependencies and link native libraries. Note: use the latest SDK version currently available, not specifically the one shown in the sample below.
# Include the Countly Class in the file that you want to use. npm install --save https://github.com/Countly/countly-sdk-react-native-bridge.git # OR npm install --save countly-sdk-react-native-bridge@20.11.0 # Linking the library to your app # react-native < 0.60. For both Android and iOS react-native link countly-sdk-react-native-bridge cd node_modules/countly-sdk-react-native-bridge/ios/ pod install cd ../../../ # react-native >= 0.60 for iOS (Android will autolink) cd ios pod install cd ..
SDK Integration
Minimal setup
We will need to call two methods (init
and start
) in order to set up our SDK. These methods should only be called once during the app's lifecycle and should be done as early as possible. Your main app component's componentDidMount
method may be a good place.
import Countly from 'countly-sdk-react-native-bridge';
if(!await Countly.isInitialized()) {
await Countly.init("https://try.count.ly", "YOUR_APP_KEY"); // Initialize the countly SDK.
Countly.start(); // start session tracking
}
Please check here for more information on how to acquire your application key (APP_KEY) and server URL.
After init
and start
have been called once, you may use the commands in the rest of this document to send additional data and metrics to your server.
If you are in doubt about the correctness of your Countly SDK integration you can learn about the verification methods from here.
Enable logging
The first thing you should do while integrating our SDK is enable logging. If logging is enabled, then our SDK will print out debug messages about its internal state and encountered problems.
Call setLoggingEnabled
on the config class to enable logging:
Countly.setLoggingEnabled(true); // Enable countly internal debugging logs
Device ID
You may provide your own custom device ID when initializing the SDK using the method below.
Countly.init(SERVER_URL, APP_KEY, DEVICE_ID)
SDK data storage
For iOS: SDK data is stored in Application Support Directory in a file named "Countly.dat" For Android: SDK data is stored in SharedPreferences. A SharedPreferences object points to a file containing key-value pairs and provides simple methods to read and write them.
Crash reporting
The Countly SDK has the ability to collect crash reports, which you may examine and resolve later on the server.
Automatic crash handling
With this feature, the Countly SDK will generate a crash report if your application crashes due to an exception and will send it to the Countly server for further inspection.
If a crash report cannot be delivered to the server (e.g. no internet connection, unavailable server, etc.), then the SDK stores the crash report locally in order to send the report again, when the connection to server is restored.
You will need to call the following method before calling init
in order to activate automatic crash reporting.
// Using Countly crash reports
Countly.enableCrashReporting();
Countly.init(...);
Automatic crash report segmentation
You may add a key/value segment to crash reports. For example, you could set which specific library or framework version you used in your app. You may then figure out if there is any correlation between the specific library or another segment and the crash reports.
Use the following function for this purpose:
var segment = {"Key": "Value"};
Countly.setCustomCrashSegments(segment);
Handled exceptions
You might catch an exception or similar error during your app’s runtime.
You may also log these handled exceptions to monitor how and when they are happening with the following command:
Countly.logException(stack, nonfatal, customSegments);
The method logException
takes a string for the stack trace, a boolean flag indicating if the crash is considered fatal or not, and a segments dictionary to add additional data to your crash report.
Below are some examples that how to log handled/nonfatal and unhandled/fatal exceptions manually.
1. Manually report handled exception
Countly.logException("STACK_TRACE_STRING", true);
2. Manually report handled exception with segmentation
Countly.logException("STACK_TRACE_STRING", true, {"_facebook_version": "0.0.1"});
3. Manually report fatal exception
Countly.logException("STACK_TRACE_STRING", false);
4. Manually report fatal exception with segmentation
Countly.logException("STACK_TRACE_STRING", false, {"_facebook_version": "0.0.1"});
Crash breadcrumbs
Throughout your app, you can leave crash breadcrumbs which would describe previous steps that were taken in your app before the crash. After a crash happens, they will be sent together with the crash report.
Following the command adds crash breadcrumb:
Countly.addCrashLog(String record)
Native C++ Crash Reporting
If you have C++ libraries in your React Native Android app, the React Native Bridge SDK allows you to record possible crashes in your Countly server by integrating the sdk-native
developed within our Android SDK. Find more information here.
As this feature is optional, you will need to do some changes in your react native android project files, to make it available.
Go to YOUR_REACT_NATIVE_PROJECT_PATH/android/app/build.gradle
and add the package dependency (please change the LATEST_VERSION
below by checking our Maven page, currently 20.11.6):
dependencies {
implementation 'ly.count.android:sdk-native:LATEST_VERSION'
}
Then call Countly.initNative()
method as early as possible in your react native android project to be able to catch setup time crashes, it should be preferably in the "onCreate" callback of the Application class.
You may find MainApplication.java
at this path:
YOUR_REACT_NATIVE_PROJECT_PATH/android/app/src/main/java/com/PROJECT_NAME
// import this in your Application class import ly.count.android.sdknative.CountlyNative; // call this function in "onCreate" callback of Application class CountlyNative.initNative(getApplicationContext());
getApplicationContext()
is needed to determine a storage place for minidump files.
Sending crash dump files to the server will be taken care of by the SDK during the next app initialization. We also provide a Gradle plugin that automatically uploads symbol files to your server (these are needed for the symbolication of crash dumps). Integrate it into your React Native project as explained in the relevant Android documentation page.
This is what the debug logs will look like if you use this feature:
$ adb logcat -s Countly:V countly_breakpad_cpp:V
# when Countly.initNative() is called
D/countly_breakpad_cpp(123): breakpad initialize succeeded. dump files will be saved at /Countly/CrashDumps
# when a crash occurs (you may trigger one by Countly.testCrash())
D/countly_breakpad_cpp(123): DumpCallback started
D/countly_breakpad_cpp(123): DumpCallback ==> succeeded path=/Countly/CrashDumps/30f6d9b8-b3b2-1553-2efe0ba2-36588990.dmp
# when app is run again after the crash
D/Countly (124): Initializing...
D/Countly (124): Checking for native crash dumps
D/Countly (124): Native crash folder exists, checking for dumps
D/Countly (124): Crash dump folder contains [1] files
D/Countly (124): Recording native crash dump: [30f6d9b8-b3b2-1553-2efe0ba2-36588990.dmp]
Events
An Event is any type of action that you can send to a Countly instance, e.g. purchases, changed settings, view enabled, and so on. This way it's possible to get much more information from your application compared to what is sent from the SDK to the Countly instance by default.
Here are the detail about properties which we can use with event:
-
key
identifies the event -
count
is the number of times this event occurred -
sum
is an overall numerical data set tied to an event. For example, total amount of in-app purchase event. -
duration
is used to record and track the duration of events. -
segmentation
is a map of key-value pairs, that can be used to track additional information.
All data passed to the Countly server via the SDK or API should be in UTF-8.
Recording events
We will be recording a purchase event below. Here is a quick summary of the information with which each usage will provide us:
- Usage 1: how many times the purchase event occurred.
- Usage 2: how many times the purchase event occurred + the total amount of those purchases.
- Usage 3: how many times the purchase event occurred + from which countries and application versions those purchases were made.
- Usage 4: how many times the purchase event occurred + the total amount, both of which are also available, segmented into countries and application versions.
1. Event key and count
var event = {"eventName":"Purchase","eventCount":1};
Countly.sendEvent(event);
2. Event key, count, and sum
var event = {"eventName":"Purchase","eventCount":1,"eventSum":"0.99"};
Countly.sendEvent(event);
3. Event key and count with segmentation(s)
var event = {"eventName":"purchase","eventCount":1};
event.segments = {"Country" : "Germany", "app_version" : "1.0"};
Countly.sendEvent(event);
4. Event key, count, and sum with segmentation(s)
var event = {"eventName":"purchase","eventCount":1};
event.segments = {"Country" : "Germany", "app_version" : "1.0","eventSum":"0.99"};
Countly.sendEvent(event);
Those are only a few examples of what you can do with events. You may extend those examples and use Country, app_version, game_level, time_of_day, and any other segmentation that will provide you with valuable insights.
Timed events
It's possible to create timed events by defining a start and a stop moment.
String eventName = "Event Name";
//start some event
Countly.startEvent(eventName);
//wait some time
//end the event
Countly.endEvent(eventName);
You may also provide additional information when ending an event. However, in that case, you have to provide the segmentation, count, and sum. The default values for those are "null", 1 and 0.
String eventName = "Event Name";
//start some event
Countly.startEvent(eventName);
var event = { "eventName": eventName, "eventCount": 1, "eventSum": "0.99" };
event.segments = { "Country": "Germany", "Age": "28" };
//end the event while also providing segmentation information, count and sum
Countly.endEvent(event);
You may cancel the started timed event in case it is not relevant anymore:
String eventName = "Event name";
//start some event
Countly.startEvent(eventName);
//wait some time
//cancel the event
Countly.cancelEvent(eventName);
View tracking
You may track custom views with the following code snippet:
Countly.recordView("View Name")
While manually tracking views, you may add your custom segmentation to them like this:
var viewSegmentation = { "Country": "Germany", "Age": "28" };
Countly.recordView("View Name", viewSegmentation);
To review the resulting data, open the dashboard and go to Analytics > Views
. For more information on how to use view tracking data to its fullest potential, click here.
Device ID management
When the SDK is initialized the first time and no custom device ID is provided, a random one will be generated. For most use cases that is enough as it provides a random identity to one of your apps users.
For iOS: the device ID generated by the SDK is the Identifier For Vendor (IDFV). For Android: the device ID generated by the SDK is the OpenUDID or Google Advertising ID.
To solve other potential use cases, we provide 3 ways to handle your device id:
- Changing device ID with merge
- Changing device ID without merge
- Using a temporary ID
Changing device ID with and without merge
You may configure or change the device ID anytime using the method below.
Countly.changeDeviceId(DEVICE_ID, ON_SERVER);
You may either allow the device to be counted as a new device or merge it with the existing data on the server. If onServer
is set to true
, the old device ID on the server will be replaced with the new one, and data associated with the old device ID will be merged automatically. Otherwise, if onServer
is set to false
, the device will be counted as a new device on the server.
Temporary Device ID
You may use a temporary device ID mode for keeping all requests on hold until the real device ID is set later.
To enable this when initializing the SDK, use the method below.
Countly.init(SERVER_URL, APP_KEY, "TemporaryDeviceID")
To enable a temporary device ID after initialization, use the method below.
Countly.changeDeviceId("TemporaryDeviceID", ON_SERVER);
Note: When passing the TemporaryDeviceID
for the deviceID
parameter, the argument for the onServer
parameter does not matter.
As long as the device ID value is TemporaryDeviceID
, the SDK will be in temporary device ID mode and all requests will be on hold, but they will be persistently stored.
When in temporary device ID mode, method calls for presenting feedback widgets and updating remote config will be ignored.
Later, when the real device ID is set using the Countly.changeDeviceId(DEVICE_ID, ON_SERVER);
method, all requests which have been kept on hold until that point will start with the real device ID.
Retrieving the device id
You may want to see what device id Countly is assigning for the specific device. For that, you may use the following calls.
String usedId = Countly().getCurrentDeviceId();
Push Notifications
Please first check our Push Notifications documentation to see how you can use this feature. Since Android and iOS handles notifications differently (from how you can send them externally to how they are handled in native code), we need to provide different instructions for these two platforms.
General Setup
First, when setting up Push for the React Native (Bridge) SDK, select the push token mode. This allows you to choose either, test or production modes. Note that the push token mode should be set before initialization. Use the method below.
// Important: call this method before init method Countly.pushTokenType(Countly.messagingMode.DEVELOPMENT, "Channel Name", "Channel Description"); // Countly.messagingMode.DEVELOPMENT // Countly.messagingMode.PRODUCTION // Countly.messagingMode.ADHOC
When you are ready to initialize Countly Push, call Countly.askForNotificationPermission()
after init
, using the method below.
// CUSTOM_SOUND_PATH is an optional parameter and currently only support Android.
Countly.askForNotificationPermission("CUSTOM_SOUND_PATH"); // This method will ask for permission, // and send push token to countly server.
With an option parameter of custom sound path for push notifications.
We will use this custom sound path to create a soundUri and set the sound of notification channel.
We recommend to add the custom sound file in your Android project res/raw folder. Always create a "raw" folder by right clicking on Resources (res) folder and select New -> Android Resource Directory.
Your custom sound path will be like this after adding it in res/raw folder:
"android.resource://PACKAGE_NAME/raw/NAME_OF_SOUND_WITHOUT_EXTENSION";
For more information about custom push notification sounds in Android check this link:
https://support.count.ly/hc/en-us/articles/360037754031-Android#custom-notification-sound
Currently custom sound feature is only available for Android.
If you would like to use a custom sound in your push notifications, they must be present on the device. They cannot be linked from the Internet.
Android Setup
Step 1: For FCM credentials setup please follow the instruction from this URL https://support.count.ly/hc/en-us/articles/360037754031-Android#getting-fcm-credentials.
Step 2: Make sure you have google-services.json
from https://firebase.google.com/
Step 3: Make sure the app package name and the google-services.json
package_name
matches.
Step 4: Place the google-services.json
file inside android/app
Step 5: Use google services latest version from this link https://developers.google.com/android/guides/google-services-plugin
Step 6: Add the following line in the file android/build.gradle
buildscript {
dependencies {
classpath 'com.google.gms:google-services:4.3.2'
}
}
Step 7: Add the following line in file android/app/build.gradle
// Add this at the bottom of the file
apply plugin: 'com.google.gms.google-services'
Note: You need to do some additional steps to handle multiple messaging services. If you are using other plugins for push notifications, please follow the instructions from this URL:
Handling multiple FCM services
Additional Intent Redirection Checks
This functionality is available since SDK version 22.02.2.
Intent Redirection Vulnerability is an issue that lets your app allow malicious apps to access private app components or files. Google removes apps from Google Play that is susceptible to Intent Redirection Vulnerability. For Push Notifications, we are also using Intent Redirection in our SDK, so for that reason, we have also implemented additional Intent Redirection protection.
By default additional intent redirection is enabled for intent redirect security, you can disable the additional intent redirection:
Countly.configureIntentRedirectionCheck([], [], false);
If these are enabled then the SDK will enforce additional security checks. More info can be found here.
If, for some reason, the 'activity name' does not start with the 'application package name' (for e.g if you are using Android Product/Build Flavors to create multiple apps with the same code base), then you need to provide the additional allowed class and package names for Intent Redirection manually.
You can set the allowed package and class names for Intent Redirection using this call:
Countly.configureIntentRedirectionCheck(["MainActivity"], ["com.countly.demo"]);
iOS Setup
Push notifications are enabled by default for iOS, but if you wish to disable them, you can define the macro "COUNTLY_EXCLUDE_PUSHNOTIFICATIONS" in the project's preprocessor macros setting. The location of this setting may vary depending on the development environment you are using.
For example, in Xcode, you can define this macro by navigating to the project settings, selecting the build target, and then selecting the "Build Settings" tab. Under the "Apple LLVM - Preprocessing" section, you will find the "Preprocessor Macros" where you can add the macro "COUNTLY_EXCLUDE_PUSHNOTIFICATIONS" to the Debug and/or Release fields. This will exclude push notifications from the build.
For iOS push notification integration please follow the instructions from here
For React Native you can find CountlyNotificationService.h/m
file under Pods/Development Pods/CountlyReactNative/CountlyNotificationService.h/m
Pro Tips to find the files from deep hierarchy:
- You can filter the files in the navigator using a shortcut ⌥⌘J (Option-Command-J), in the filter box type "CountlyNotificationService" and it will show the related files only.
- You can find the file using the shortcut ⇧⌘O (Shift-Command-O) and then navigate to that file using the shortcut ⇧⌘J (Shift-Command-J)
You can drag and drop both .h and .m files from Pod to Compile Sources.
Handling push callbacks
To register a Push Notification callback after initialising the SDK, use the method below.
Countly.registerForNotification(function(theNotification){ console.log(JSON.stringify(theNotification)); });
In order to listen to notifications received and the click events, add the code below in AppDelegate.m
Add header files
#import "CountlyReactNative.h"
#import <UserNotifications/UserNotifications.h>
Add this call [CountlyReactNative startObservingNotifications];
in didFinishLaunchingWithOptions:
method to handle push notification receive and action callbacks when SDK is not initialized.
This functionality is available since SDK version 22.06.1
// For push notification received and action callbacks.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[CountlyReactNative startObservingNotifications];
}
Before @end
add these method
// Required for the notification event. You must call the completion handler after handling the remote notification.
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler
{
[CountlyReactNative onNotification: userInfo];
completionHandler(0);
}
// When app is killed.
- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)(void))completionHandler{
[CountlyReactNative onNotificationResponse: response];
completionHandler();
}
// When app is running.
- (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler{
[CountlyReactNative onNotification: notification.request.content.userInfo];
completionHandler(0);
}
Data Structure Received in Push Callbacks
Here is the example of how data will receive in push callbacks:
Data Received for Android platform:
{
"c.e.cc": "TR",
"c.e.dt": "mobile",
"Key": "value",
"c.i": "62b59b979f05a1f5e5592036",

"title": "title",
"subtitle": "subtitle",
"body": "Message"
},
"badge": 1,
"sound": "custom"
},
"Key": "value"
}
User Location
Countly allows you to send geolocation-based push notifications to your users. By default, the Countly Server uses the GeoIP database to deduce a user's location.
Set User Location
If your app has a different way of detecting location, you may send this information to the Countly Server by using the setLocationInit
orsetLocation
methods.
We recommend using the setLocationInit
method before initialization to sent location. This includes:
-
countryCode
a string in ISO 3166-1 alpha-2 format country code -
city
a string specifying city name -
location
a string comma-separated latitude and longitude -
IP
a string specifying an IP address in IPv4 or IPv6 formats
// Example for setLocationInit
var countryCode = "us";
var city = "Houston";
var latitude = "29.634933";
var longitude = "-95.220255";
var ipAddress = "103.238.105.167";
Countly.setLocationInit(countryCode, city, latitude + "," + longitude, ipAddress);
Geolocation recording methods may also be called at any time after the Countly SDK has started. To do so, use the setLocation
method as shown below.
// Example for setLocation
var countryCode = "us";
var city = "Houston";
var latitude = "29.634933";
var longitude = "-95.220255";
var ipAddress = "103.238.105.167";
Countly.setLocation(countryCode, city, latitude + "," + longitude, ipAddress);
Disable Location
To erase any cached location data from the device and stop further location tracking, use the following method. Note that if after disabling location, the setLocation
is called with any non-null value, tracking will resume.
//disable location tracking
Countly.disableLocation();
Remote Config
Remote config allows you to modify how your app functions or looks by requesting key-value pairs from your Countly server. The returned values may be modified based on the user profile. For more details, please see the Remote Config documentation.
Manual Remote Config download
There are three ways for manually requesting a remote config update:
- Manually updating everything
- Manually updating specific keys
- Manually updating everything except specific keys.
Each of these requests also has a callback. If the callback returns a non-null value, the request will encounter an error and fail.
The remoteConfigUpdate
replaces all stored values with the ones from the server (all locally stored values are deleted and replaced with new ones). The advantage is that you can make the request whenever it is desirable for you. It has a callback to let you know when it has finished.
Countly.remoteConfigUpdate(function(data){
console.log(data);
});
Or you might only want to update specific key values. To do so, you will need to call updateRemoteConfigForKeysOnly
with the list of keys you would like to be updated. That list is an array with the string values of those keys. It has a callback to let you know when the request has finished.
Countly.updateRemoteConfigForKeysOnly(){
Countly.updateRemoteConfigForKeysOnly(["aa", "bb"],function(data){
console.log(data);
});
Or you might want to update all the values except a few defined keys. To do so, call updateRemoteConfigExceptKeys
. The key list is an array with string values of the keys. It has a callback to let you know when the request has finished.
Countly.updateRemoteConfigExceptKeys(["aa", "bb"],function(data){
console.log(data);
});
When making requests with an "inclusion" or "exclusion" array, if those arrays are empty or null, they will function the same as a simple manual request and will update all the values. This means it will also erase all keys not returned by the server.
Getting Remote Config values
To request a stored value, call getRemoteConfigValueForKey
or getRemoteConfigValueForKeyP
with the specified key.
Countly.getRemoteConfigValueForKey("KeyName", function(data){
console.log(data);
});
var data = await Countly.getRemoteConfigValueForKeyP("KeyName");
Clearing Stored Remote Config values
At some point, you might like to erase all the values downloaded from the server. You will need to call one function to do so.
Countly.remoteConfigClearValues();
User Feedback
There are a different ways of receiving feedback from your users: the Star-rating dialog, the Ratings widget, and the Surveys widgets (Surveys and NPS®).
The Star-rating dialog allows users to give feedback as a rating from 1 to 5. The Ratings widget allows users to rate using the same 1 to 5 emoji-based rating system as well as leave a text comment. The Surveys widgets (Surveys and NPS®) allow for even more targeted feedback from users.
Ratings
Star Rating Dialog
The Star-rating integration provides a dialog for getting user feedback about an application. It contains a title, a simple message explaining its purpose, a 1 through 5-star meter for getting users rating, and a dismiss button in case the user does not want to give a rating.
This star rating has nothing to do with Google Play Store ratings and reviews. It is simply for getting brief feedback from your users to be displayed on the Countly dashboard. If the user dismisses the star-rating dialog without giving a rating, the event will not be recorded.
Countly.showStarRating();
The star-rating dialog's title, message, and dismiss button text may be customized either through the init
function or the SetStarRatingDialogTexts
function.
Countly.SetStarRatingDialogTexts("Custom title", "Custom message", "Custom dismiss button text");
Rating Widget
The rating widget displays a server-configured widget to your user devices.
All the text fields in the example above can be configured and replaced with a custom string of your choice.
In addition to a 1 through 5 rating, it is possible for users to leave a text comment and an email, should the user like to be contacted by the app developer.
Showing the rating widget in a single call involves a two-set process: before it is shown, the SDK tries to contact the server to get more information about the dialog. Therefore, a network connection to it is needed.
To display the widget after initializing the SDK, you will first need to get the widget ID from your server, as shown below.
Then, call the function to show the widget popup using the widget ID below.
Countly.presentRatingWidgetWithID("WidgetId", "Button Text", function(error){
if (error != null) {
console.log(error);
}
});
Feedback Widget
It is possible to display 2 kinds of Surveys widgets: NPS and Surveys. Both widgets are shown as webviews and they both use the same code methods.
Before any Surveys widget can be shown, you need to create them in your Countly Dashboard.
When the widgets are created, you need to use 2 calls in your SDK: one to get all available widgets for a user and another to display, a chosen widget.
To get your available widget list, use the call below.
Countly.getFeedbackWidgets(function(retrivedWidgets, error){
if (error != null) {
console.log("Error : " + error);
}
else {
console.log(retrivedWidgets.length)
}
});
From the callback, get the list of all available widgets that apply to the current device ID.
The objects in the returned list look like this:
{
"id" : "WIDGET_ID",
"type" : "WIDGET_TYPE",
"name" : "WIDGET_NAME",
}
To determine what kind of widget that is, check the "type" value. The potential values are survey
and nps
.
Then use the widget type and description (which is the same as provided in the Dashboard) to decide which widget to show.
After you have decided which widget you want to display, call the function below.
Countly.presentFeedbackWidgetObject(RETRIEVED_WIDGET_OBJECT, "CLOSE_BUTTON_TEXT", function() {
console.log("WidgetshownCallback");
},
function() {
console.log("WidgetclosedCallabck");
})
User Profiles
You can provide Countly any details you may have about your user or visitor. This will allow you to track each specific user on the "User Profiles" tab, available in Countly Enterprise Edition. For more information, please review the User Profiles documentation.
User details can be sent to your Countly instance in two separate ways depending on your needs and use case. The first option is to set the user data in bulk by using Countly.userDataBulk
call. This allows you to bundle up all your user detail information in a single request to the server and helps minimize the traffic to your server. If you have access to multiple user details of your visitors at a given time, using this method would be the preferred option
The second option is using Countly.userData
calls to send user details to your server as separate requests. This can be useful in situations where you gain access to user information one at a time and you would like to report that info to your server on the fly.
Using Countly.userDataBulk
call requires you to call Countly.userDataBulk.save()
call, manually, to trigger sending data to your server, as a signifier marking the end of user details you want to record. In the case of Countly.userData
though, you will not need to use any other methods to initiate the data transmission. It will handle that logic internally.
Note: There is some inconsistency in underlying iOS and Android code when using the bulk mode. This problem surfaces when modifying the same key multiple times. For iOS it keeps the last value for a key on all push/pull user property calls, for Android it will try to combine them. For now the work around is that you need to call the “Countly.userDataBulk.save();” after every push/pull user property call. This does eliminate some of the potential gains of this mode, but it does result in the expected result server-side.
Snippets below show examples of using these calls in various situations. After you send a user’s data, it can be found in your Dashboard under Users > User Profiles
.
Setting Predefined Values
Predefined user properties are a set of default keys that are commonly used in visitor data collection.
Bellow you can see how this can be set using the regular user property access mode and using the bulk mode:
var options = {};
options.name = "Nicola Tesla";
options.username = "nicola";
options.email = "info@nicola.tesla";
options.organization = "Trust Electric Ltd";
options.phone = "+90 822 140 2546";
options.picture = "http://www.trust.electric/images/people/nicola.png";
options.picturePath = "";
options.gender = "M";
options.byear = 1919;
Countly.setUserData(options);
var options = {};
options.name = "Name of User";
options.username = "Username";
options.email = "User Email";
options.organization = "User Organization";
options.phone = "User Contact number";
options.picture = "https://count.ly/images/logos/countly-logo.png";
options.picturePath = "";
options.gender = "Male";
options.byear = 1989;
Countly.userDataBulk.setUserProperties(options);
// Unless you call this last function your data would not be sent to your server
Countly.userDataBulk.save();
Setting Custom Values
Custom user properties are any arbitrary values that you would like to store under your user's profile. These values can be internal IDs, registration dates, horoscopes, or any other value that is not included in the predefined user properties.
var options = {};
options.customeValueA = "nicola";
options.customeValueB = "info@nicola.tesla";
// ...
Countly.setUserData(options);
var options = {};
options.customeValueA = "Custom value A";
options.customeValueB = "Custom value B";
// ...
Countly.userDataBulk.setUserProperties(options);
// Unless you call this last function your data would not be send to your server
Countly.userDataBulk.save();
Modifying Data
Additionally, you can modify these custom values in various ways like increasing a number, pushing new values to an array, etc. You can see the whole range of operations below.
Countly.userData.setProperty("keyName", "keyValue"); //set custom property
Countly.userData.setOnce("keyName", 200); //set custom property only if property does not exist
Countly.userData.increment("keyName"); //increment value in key by one
Countly.userData.incrementBy("keyName", 10); //increment value in key by provided value
Countly.userData.multiply("keyName", 20); //multiply value in key by provided value
Countly.userData.saveMax("keyName", 100); //save max value between current and provided
Countly.userData.saveMin("keyName", 50); //save min value between current and provided
Countly.userData.setOnce("setOnce", 200);//insert value to array of unique values
Countly.userData.pushUniqueValue("type", "morning");//insert value to array of unique values
Countly.userData.pushValue("type", "morning");//insert value to array which can have duplicates
Countly.userData.pullValue("type", "morning");//remove value from array
Promise.allSettled([Countly.userDataBulk.setProperty("key", "value"),
Countly.userDataBulk.setProperty("increment", 5),
Countly.userDataBulk.increment("increment"),
Countly.userDataBulk.setProperty("incrementBy", 5),
Countly.userDataBulk.incrementBy("incrementBy", 10),
Countly.userDataBulk.setProperty("multiply", 5),
Countly.userDataBulk.multiply("multiply", 20),
Countly.userDataBulk.setProperty("saveMax", 5),
Countly.userDataBulk.saveMax("saveMax", 100),
Countly.userDataBulk.setProperty("saveMin", 5),
Countly.userDataBulk.saveMin("saveMin", 50),
Countly.userDataBulk.setOnce("setOnce", 200),
Countly.userDataBulk.pushUniqueValue("type", "morning"),
Countly.userDataBulk.pushValue("type", "morning"),
Countly.userDataBulk.pullValue("type", "morning")])
.then(values => {
// We need to call the "save" in then block else it will cause a race condition and "save" may call before all the user profiles calls are completed
Countly.userDataBulk.save();
})
Application Performance Monitoring
The Performance Monitoring feature allows you to analyze your application's performance on various aspects. For more details, please review the Performance Monitoring documentation.
Here is how you can utilize the Performance Monitoring feature in your apps:
First, you need to enable the Performance Monitoring feature:
// Enable APM features.
Countly.enableApm();
With this, the Countly SDK will start measuring some performance traces automatically, including app foreground time, app background time. Additionally, custom traces and network traces can be manually recorded.
App Start Time
For the app start time to be recorded, you need to call the appLoadingFinished
method. Make sure this method is called after init
.
// Example of appLoadingFinished
await Countly.init("https://try.count.ly", "YOUR_APP_KEY");
Countly.appLoadingFinished();
This calculates and records the app launch time for performance monitoring. It should be called when the app is loaded and it successfully displayed its first user-facing view. E.g. componentDidMount:
method or wherever is suitable for the app's flow. The time passed since the app has started to launch will be automatically calculated and recorded for performance monitoring. Note that the app launch time can be recorded only once per app launch. So, the second and following calls to this method will be ignored.
Custom trace
You may also measure any operation you want and record it using custom traces. First, you need to start a trace by using the startTrace(traceKey)
method:
Countly.startTrace(traceKey);
Then you may end it using the endTrace(traceKey, customMetric)
method, optionally passing any metrics as key-value pairs:
String traceKey = "Trace Key"; Map<String, int> customMetric = { "ABC": 1233, "C44C": 1337 }; Countly.endTrace(traceKey, customMetric);
The duration of the custom trace will be automatically calculated upon ending.
Trace names should be non-zero length valid strings. Trying to start a custom trace with the already started name will have no effect. Trying to end a custom trace with already ended (or not yet started) name will have no effect.
You may also cancel any custom trace you started using the cancelTrace(traceKey)
method:
Countly.cancelTrace(traceKey);
Additionally, if you need you may cancel all custom traces you started, using the clearAllTraces()
method:
Countly.clearAllTraces(traceKey);
Network trace
You may record manual network traces using the recordNetworkTrace(networkTraceKey, responseCode, requestPayloadSize, responsePayloadSize, startTime, endTime)
method.
A network trace is a collection of measured information about a network request. When a network request is completed, a network trace can be recorded manually to be analyzed via Performance Monitoring later using the following parameters:
- networkTraceKey
: A non-zero length valid string - responseCode
: HTTP status code of the received response - requestPayloadSize
: Size of the request's payload in bytes - responsePayloadSize
: Size of the received response's payload in bytes - startTime
: UNIX timestamp in milliseconds for the starting time of the request - endTime
: UNIX timestamp in milliseconds for the ending time of the request
Countly.recordNetworkTrace(networkTraceKey, responseCode, requestPayloadSize, responsePayloadSize, startTime, endTime);
User consent
Being compliant with GDPR and other data privacy regulations, Countly provides ways to toggle different Countly tracking features on or off depending on a user's given consent. For more details, please review the Compliance Hub plugin documentation.
Currently, available features with consent control are as follows:
- sessions - tracking when, how often, and how long users use your app
- events - allows sending events to the server
- views - allows tracking which views user visits
- location - allows sending location information
- crashes - allows tracking crashes, exceptions, and errors
- attribution - allows tracking from which campaign did the user come.
- users - allows collecting and providing user information, including custom properties.
- push - allows push notifications,
- star-rating - allows sending the results from Rating Feedback widgets.
- feedback - allows showing the results from Survey and NPS® Feedback widgets.
- apm - allows application performance monitoring.
- remote-config - allows downloading remote config values from your server.
Since the React Native Bridge SDK employs our iOS and Android SDKs, you may also be interested in reviewing their relevant documentation on this topic (iOS Consents and Android Consents).
Next we will go over the methods that are available in this SDK.
Method | Parameters / Examples | Description |
---|---|---|
setRequiresConsent |
boolean |
The requirement for checking consent is disabled by default. To enable it, you will have to call |
giveConsentInit |
string array of strings |
To add consent for a single feature (string parameter) or a subset of features (array of strings parameter). Use this method for giving consent before initializing. |
giveConsent |
string array of strings |
To add consent for a single feature (string parameter) or a subset of features (array of strings parameter). Use this method for giving consent after initializing. |
removeConsent |
string array of strings |
To remove consent for a single feature (string parameter) or a subset of features (array of strings parameter). |
giveAllConsent |
none | To give consent for all available features. |
removeAllConsent |
none | To remove consent for all available features. |
// Usage examples
Countly.setRequiresConsent(true);
// for a single feature
Countly.giveConsentInit("events");
Countly.giveConsent("events");
Countly.removeConsent("events");
// for a subset of features
Countly.giveConsentInit(["events", "views", "star-rating", "crashes"]);
Countly.giveConsent(["events", "views", "star-rating", "crashes"]);
Countly.removeConsent(["events", "views", "star-rating", "crashes"]);
// for all available features
Countly.giveAllConsent();
Countly.removeAllConsent();
The string values corresponding to the features that will be used in the giveConsent
or removeConsent
methods may be found here. In addition, please review our platform SDK documents if the feature is applicable or not for that platform.
Security and privacy
Parameter tampering protection
You can set optional salt
to be used for calculating checksum of request data, which will be sent with each request using &checksum
field. You need to set exactly the same salt
on the Countly server. If salt
on Countly server is set, all requests would be checked for the validity of &checksum
field before being processed.
// sending data with salt
Countly.enableParameterTamperingProtection("salt");
Make sure not to use salt on the Countly server and not on the SDK side, otherwise, Countly won't accept any incoming requests.
Pinned Certificate (Call this method before initialization)
Terminal
openssl s_client -connect try.count.ly:443 -showcerts
Run the above command and copy the content inside the begin certificate and the end certificate.
Example files: Android and iOS. Note that Android needs the certificate string, while iOS needs the entire .cer file.
Android
cd AwesomeProject ls count.ly.cer mkdir -p ./android/app/src/main/assets/ cp ./count.ly.cer ./android/app/src/main/assets/
iOS
open ./ios/AwesomeProject.xcworkspace Right click on AwesomeProject and select `New Group` (ScreenShot 1). Name it `Resources`. Drag and Drop count.ly.cer file under that folder (ScreenShot 2). Make sure copy bundle resources has your certificate (Screenshot 4).
JavaScript
Countly.pinnedCertificates("count.ly.cer");
Note that count.ly.cer
is the name of the file. Replace this file with the one you have.
Other features
Custom Metrics
This feature is only supported by the minimum SDK version 20.11.7.
For overriding default metrics or adding extra ones that are sent with begin_session requests, you can use pass 'customMetric' Object to the function Countly.setCustomMetrics(customMetric)
, 'customMetric' should be an Object with keys and values that are both Strings only. Note that the custom metrics should be set before initialization.
var customMetric = {"key": "value"};
Countly.setCustomMetrics(customMetric);
For overriding default metrics, keys should be one of the below String value's:
"_device"
"_device_type"
"_os"
"_os_version"
"_app_version"
"_carrier"
"_resolution"
"_density"
"_locale"
Example to override 'Carrier' and 'App Version'
var customMetric = {"_carrier": "custom carrier", "_app_version": "2.1"};
Countly.setCustomMetrics(customMetric);
Attribution analytics & install campaigns
Countly Attribution Analytics allows you to measure the performance of your marketing campaign by attributing installs from specific campaigns. This feature is available for the Enterprise Edition.
For version 20.11.4 and greater we highly recommend allowing Countly to listen to the INSTALL_REFERRER intent in order to receive more precise attribution on Android, something you may do by adding the following XML code to your AndroidManifest.xml file inside the application tag.
<receiver android:name="ly.count.android.sdk.ReferrerReceiver" android:exported="true">
<intent-filter>
<action android:name="com.android.vending.INSTALL_REFERRER" />
</intent-filter>
</receiver>
For more information about how to set up your campaigns, please review this documentation.
Call the method below before initialization.
// Enable to measure your marketing campaign performance by attributing installs from specific campaigns. Countly.enableAttribution();
For iOS 14+ use the recordAttributionID("IDFA")
function instead of Countly.enableAttribution()
You can use Countly.recordAttributionID
function to specify IDFA for campaign attribution
Countly.recordAttributionID("IDFA_VALUE_YOU_GET_FROM_THE_SYSTEM");
For iOS 14+, due to the changes made by Apple regarding Application Tracking, you need to ask the user for permission to track the Application.
For IDFA you can use this Plugin, which also supports iOS 14+ changes for Application tracking permission: https://github.com/ijunaid/react-native-advertising-id.git
Here is how to use this plugin with the Countly attribution feature:
npm install --save https://github.com/ijunaid/react-native-advertising-id.git cd ./ios pod install NSUserTrackingUsageDescription Add "Privacy - Tracking Usage Description" in your ios info.plist file. #Example Code for Countly attribution feature to support iOS 14+. import RNAdvertisingId from 'react-native-advertising-id'; if (Platform.OS.match("ios")) { RNAdvertisingId.getAdvertisingId() .then(response => { Countly.recordAttributionID(response.advertisingId); }) .catch(error => console.error(error)); } else { Countly.enableAttribution(); // Enable to measure your marketing campaign performance by attributing installs from specific campaigns. }
Forcing HTTP POST
If the data sent to the server is short enough, the SDK will use HTTP GET requests. In the event you would like an override so that HTTP POST may be used in all cases, call the setHttpPostForced
function after you have called init
. You may use the same function later in the app’s life cycle to disable the override. This function has to be called every time the app starts, using the method below.
// enabling the override
Countly.setHttpPostForced(true);
// disabling the override
Countly.setHttpPostForced(false);
Checking if init has been called
In the event you would like to check if init has been called, use the function below.
Countly.isInitialized().then(result => console.log(result)); // true or false
Checking if onStart has been called
For some applications, there might be a use case where the developer would like to check if the Countly SDK onStart function has been called. To do so, use the call below.
Countly.hasBeenCalledOnStart().then(result => console.log(result)); // true or false
Interacting with the internal request queue
When recording events or activities, the requests don't always get sent immediately. Events get grouped together. All the requests contain the same app key which is provided in the init
function.
There are two ways to interact with the app key in the request queue at the moment.
1. You can replace all requests with a different app key with the current app key:
//Replaces all requests with a different app key with the current app key. Countly.replaceAllAppKeysInQueueWithCurrentAppKey();
In the request queue, if there are any requests whose app key is different than the current app key, these requests app key will be replaced with the current app key. 2. You can remove all requests with a different app key in the request queue:
//Removes all requests with a different app key in request queue. Countly.removeDifferentAppKeysFromQueue();
In the request queue, if there are any requests whose app key is different than the current app key, these requests will be removed from the request queue.
Setting an event queue threshold
Events get grouped together and are sent either every minute or after the unsent event count reaches a threshold. By default it is 10. If you would like to change this, call:
Countly.setEventSendThreshold(6);
