Installation

$ npm install react-native-appsflyer --save

iOS

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

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

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

2. 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. Copy RNAppsFlyer.h and RNAppsFlyer.m from node_modules ➜ react-native-appsflyer to your project directory

Breaking Changes for react-native >= 0.40.0:

In RNAppsFlyer.h:

#import <React/RCTBridgeModule.h>  //for react-native ver >= 0.40
//#import "RCTBridgeModule.h"        //for react-native ver < 0.40

In RNAppsFlyer.m:

// for react-native ver >= 0.40
#import <React/RCTBridge.h>
#import <React/RCTEventDispatcher.h>

// for react-native ver < 0.40
//#import "RCTBridge.h"
//#import "RCTEventDispatcher.h"

Android

android/app/build.gradle

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')

For Google Install referrer support:

Open the build.gradle file for your application. Make sure that the repositories section includes a maven section with the "https://maven.google.com" endpoint. For example:

allprojects {
    repositories {
        jcenter()
        maven {
            url "https://maven.google.com"
        }
    }
}

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(MainApplication.this)

So getPackages() should look like:

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

API Methods

appsFlyer.initSdk(options, callback): void

initializes the SDK.

const options = {
devKey: "<AF_DEV_KEY>",
isDebug: true
};

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

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

const userId = "some_user_id";

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

appsFlyer.setCollectIMEI = (isCollect, successCallback): void

By default, IMEI and Android ID are not collected by the SDK if the OS version is higher than KitKat (4.4) and the device contains Google Play Services (on SDK versions 4.8.8 and below the specific app needed GPS).

appsFlyer.setCollectIMEI(false,
        (result) => {
           console.log("setCollectIMEI ...");
         });

appsFlyer.setCollectAndroidID = (isCollect, successCallback): void

By default, IMEI and Android ID are not collected by the SDK if the OS version is higher than KitKat (4.4) and the device contains Google Play Services (on SDK versions 4.8.8 and below the specific app needed GPS).

appsFlyer.setCollectAndroidID(false,
        (result) => {
           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).
• The trackEvent method allows you to send in-app events to AppsFlyer analytics. This method allows you to add events dynamically by adding them directly to the application code.

const eventName = "af_add_to_cart";
const eventValues = {
"af_content_id": "id123",
"af_currency":"USD",
"af_revenue": "2"
};

appsFlyer.trackEvent(eventName, eventValues,
(result) => {
console.log(result);
},
(error) => {
console.error(error);
}
)

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];
}

Android

appsFlyer.enableUninstallTracking(GCMProjectID): void (Android only)

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

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.

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.

componentDidMount() {
Linking.getInitialURL().then((url) => {
if (appsFlyer) {
appsFlyer.sendDeepLinkData(url); // Report Deep Link to AppsFlyer
// Additional Deep Link Logic Here ...
}
}).catch(err => console.error('An error occurred', err));
}

appsFlyer.setUserEmails(options, errorC, successC): void

AppsFlyer enables you to report one or more of the device’s associated email addresses. You must collect the email addresses and report it to AppsFlyer according to your required encryption method. More info you can find on AppsFlyer-SDK-Integration-Android and AppsFlyer-SDK-Integration-iOS

options

Example:

const options = {
"emailsCryptType": 2,
"emails": [
"user1@gmail.com",
"user2@gmail.com"
]
};

appsFlyer.setUserEmails(options,
(response) => {
this.setState({ ...this.state, setUserEmailsResponse: response });
},
(error) => {
console.error(error);
}
);

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;
}
