Installation

$ npm install react-native-appsflyer --save

iOS

1. Add the appsFlyerFramework to podfile and run pod install.

Example:

pod 'react-native-appsflyer',
:path => '../node_modules/react-native-appsflyer'

This assumes your Podfile is located in ios directory.

You must also have the React dependencies defined in the Podfile as described here.

1. Run pod install (inside ios directory).

Manual Integration (Integrating without Cocoapods):

1. Download the Static Lib of the AppsFlyer iOS SDK from here: https://support.appsflyer.com/hc/en-us/articles/207032066-AppsFlyer-SDK-Integration-iOS#2-quick-start
2. Unzip and copy the contents of the Zip file into your project directory
3. Run react-native link react-native-appsflyer from of the project root or copy RNAppsFlyer.h and RNAppsFlyer.m from node_modules ➜ react-native-appsflyer to your project directory

Android

android/app/build.gradle

Run react-native link react-native-appsflyer from of the project root or add manually:

Add the project to your dependencies

dependencies {
...
compile project(':react-native-appsflyer')
}

android/settings.gradle

Add the project

include ':react-native-appsflyer'
project(':react-native-appsflyer').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-appsflyer/android')

If you need to override sdk version, add custom configuration to your root gradle, for example:

ext {
    minSdkVersion = 16
    targetSdkVersion = 25
    compileSdkVersion = 25
    buildToolsVersion = '25.0.3'
}

Build project so you should get following dependency (see an Image):

MainApplication.java

Add:

1. import com.appsflyer.reactnative.RNAppsFlyerPackage;

2. In the getPackages() method register the module: new RNAppsFlyerPackage()

So getPackages() should look like:

    @Override
    protected List<ReactPackage> getPackages() {
      return Arrays.<ReactPackage>asList(
            new MainReactPackage(),
            //...
            new RNAppsFlyerPackage()
            //...
      );
    }

API Methods

---

Call module by adding:

import appsFlyer from 'react-native-appsflyer';

---

appsFlyer.initSdk(options, callback): void

initializes the SDK.

parameter	type	description
options	Object	SDK configuration

options

name	type	default	description
devKey	string		Appsflyer Dev key
appId	string		Apple Application ID (for iOS only)
isDebug	boolean	false	debug mode (optional)

Example:

};

if (Platform.OS === 'ios') {
options.appId = "123456789";
}

appsFlyer.initSdk(options,
(result) => {
console.log(result);
},
(error) => {
console.error(error);
}
)

With Promise:

try {
     var result = await appsFlyer.initSdk(options);     
     } catch (error) {
    }

---

appsFlyer.trackAppLaunch(): void

Necessary for tracking sessions and deep link callbacks in iOS on background-to-foreground transitions. Should be used with the relevant AppState logic.

Example:

state = {
appState: AppState.currentState
}

componentDidMount() {
AppState.addEventListener('change', this._handleAppStateChange);
}

componentWillUnmount() {
if(this.onInstallConversionDataCanceller){
this.onInstallConversionDataCanceller();
}
AppState.removeEventListener('change', this._handleAppStateChange);
}

_handleAppStateChange = (nextAppState) => {
if (this.state.appState.match(/inactive|background/) && nextAppState === 'active') {

if (Platform.OS === 'ios') {
appsFlyer.trackAppLaunch();
}
}

if (this.state.appState.match(/active|foreground/) && nextAppState === 'background') {
if(this.onInstallConversionDataCanceller){
this.onInstallConversionDataCanceller();
}
}

this.setState({appState: nextAppState});
}

---

appsFlyer.setCustomerUserId(customerUserId, callback): void

Setting your own Custom ID enables you to cross-reference your own unique ID with AppsFlyer’s user ID and the other devices’ IDs. This ID is available in AppsFlyer CSV reports along with postbacks APIs for cross-referencing with you internal IDs.

Note: The ID must be set during the first launch of the app at the SDK initialization. The best practice is to call this API during the deviceready event, where possible.

parameter	type	description
customerUserId	String

Example:

const userId = "some_user_id";

appsFlyer.setCustomerUserId(userId,
(response) => {
//..

           console.log("setCollectAndroidID ... ");
         });

---

appsFlyer.trackEvent(eventName, eventValues, successC, errorC): void

• These in-app events help you track how loyal users discover your app, and attribute them to specific campaigns/media-sources. Please take the time define the event/s you want to measure to allow you to track ROI (Return on Investment) and LTV (Lifetime Value).

Track App Uninstalls

iOS

AppsFlyer enables you to track app uninstalls. To handle notifications it requires to modify your AppDelegate.m. Use didRegisterForRemoteNotificationsWithDeviceToken to register to the uninstall feature.

Example:

@import AppsFlyerLib;

...

- (void)application:(UIApplication ​*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *​)deviceToken {
// notify AppsFlyerTracker
[[AppsFlyerTracker sharedTracker] registerUninstall:deviceToken];
}

parameter	type	description
GCMProjectID	String
callback	(successString) => void	Required at the moment, inject a string as parameter upon hook registration success.

Example:

enableUninstallTracking(){
const  gcmProjectNum = "987186475229";
appsFlyer.enableUninstallTracking(gcmProjectNum,
(success) => {
//...
})
}

appsFlyer.onInstallConversionData(callback): function:unregister

Accessing AppsFlyer Attribution / Conversion Data from the SDK (Deferred Deeplinking). Read more: Android, iOS

parameter	type	description
callback	function	returns object

callback structure:

• status: "success"or "failure" if SDK returned error on onInstallConversionData event handler
• type:
• "onAppOpenAttribution" - returns deep linking data (non-organic)
• "onInstallConversionDataLoaded" - called on each launch
• "onAttributionFailure"
• "onInstallConversionFailure"
• data: some metadata, for example:

{
"status": "success",
"type": "onInstallConversionDataLoaded",
"data": {
"af_status": "Organic",
"af_message": "organic install"
}
}

The code implementation fro the conversion listener must be made prior to the initialisation code of the SDK

Example:

this.onInstallConversionDataCanceller = appsFlyer.onInstallConversionData(
(data) => {
console.log(data);
}
);

appsFlyer.initSdk(...);

The appsFlyer.onInstallConversionData returns function to unregister this event listener. Actually it calls NativeAppEventEmitter.remove()

Example:

state = {
appState: AppState.currentState
}

componentDidMount() {
AppState.addEventListener('change', this._handleAppStateChange);
}

componentWillUnmount() {
if(this.onInstallConversionDataCanceller){
this.onInstallConversionDataCanceller();
}
AppState.removeEventListener('change', this._handleAppStateChange);
}

_handleAppStateChange = (nextAppState) => {
if (this.state.appState.match(/inactive|background/) && nextAppState === 'active') {

if (Platform.OS === 'ios') {
appsFlyer.trackAppLaunch();
}
}

if (this.state.appState.match(/active|foreground/) && nextAppState === 'background') {
if(this.onInstallConversionDataCanceller){
this.onInstallConversionDataCanceller();
}
}

this.setState({appState: nextAppState});
}

---

appsFlyer.getAppsFlyerUID(callback): void

Get AppsFlyer’s proprietary Device ID. The AppsFlyer Device ID is the main ID used by AppsFlyer in Reports and APIs.

parameter	type	description
error	String	Error callback - called on getAppsFlyerUID failure
appsFlyerUID	string	The AppsFlyer Device ID

Example:

appsFlyer.getAppsFlyerUID((error, appsFlyerUID) => {
if (error) {
console.error(error);
} else {
console.log("on getAppsFlyerUID: " + appsFlyerUID);
}
});

---

appsFlyer.trackLocation(longitude, latitude, callback(error, coords): void (iOS only)

Get AppsFlyer’s proprietary Device ID. The AppsFlyer Device ID is the main ID used by AppsFlyer in Reports and APIs.

Example:

const latitude = -18.406655;
const longitude = 46.406250;

appsFlyer.trackLocation(longitude, latitude, (error, coords) => {
if (error) {
console.error(error);
} else {
this.setState({ ...this.state, trackLocation: coords });
}
});

---

appsFlyer.sendDeepLinkData(String url): void (Android only)

Report Deep Links for Re-Targeting Attribution (Android). This method should be called when an app is opened using a deep link.

Example:

componentDidMount() {
Linking.getInitialURL().then((url) => {
if (appsFlyer) {

iOS Deep Links - Universal Links and URL Schemes

In order to track retargeting and use the onAppOpenAttribution callbacks in iOS, the developer needs to pass the User Activity / URL to our SDK, via the following methods in the AppDelegate.m file:

Universal Links (iOS 9 +)

- (BOOL) application:(UIApplication *)application continueUserActivity:(NSUserActivity *)userActivity restorationHandler:(void (^)(NSArray *_Nullable))restorationHandler
{
[[AppsFlyerTracker sharedTracker] continueUserActivity:userActivity restorationHandler:restorationHandler];
return YES;
}

URL Schemes

// Reports app open from deep link from apps which do not support Universal Links (Twitter) and for iOS8 and below
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString*)sourceApplication annotation:(id)annotation {
[[AppsFlyerTracker sharedTracker] handleOpenURL:url sourceApplication:sourceApplication withAnnotation:annotation];
return YES;
}

// Reports app open from URL Scheme deep link for iOS 10
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url
options:(NSDictionary *) options {
[[AppsFlyerTracker sharedTracker] handleOpenUrl:url options:options];
return YES;
}
