Getting started

Deep Linking Types

1. Deferred Deep Linking - Serving personalized content to new or former users, directly after the installation.
2. Direct Deep Linking - Directly serving personalized content to existing users, which already have the mobile app installed.

Unified deep linking (UDL) - an API which enables you to send new and existing users to a specific in-app activity as soon as the app is opened.

For more info please check out the OneLink™ Deep Linking Guide and developer guide.

Android Deeplink Setup

AppsFlyer SDK inspects activity intent object during onResume(). Because of that, for each activity that may be configured or launched with any non-standard launch mode please make sure to add the following code to MainActivity.java in android/app/src/main/java/com...:

...
import android.content.Intent;
...
public class MainActivity extends ReactActivity {
...
    @Override
    public void onNewIntent(Intent intent) {
         super.onNewIntent(intent);
         setIntent(intent);
    }
 }

App Links

First, you need to generate SHA256 fingerprint, then add the following intent-filter to the relevant activity in your app’s manifest:

<intent-filter android:autoVerify="true">
    <action android:name="android.intent.action.VIEW" />

    <category android:name="android.intent.category.DEFAULT" />
    <category android:name="android.intent.category.BROWSABLE" />
    <data
        android:host="onelink-basic-app.onelink.me"
        android:scheme="https" />
</intent-filter>

For more on App Links check out the guide here.

URI Scheme

In your app’s manifest add the following intent-filter to your relevant activity:

<intent-filter>
    <action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.DEFAULT" />
    <category android:name="android.intent.category.BROWSABLE" />

    <data
        android:host="mainactivity"
        android:scheme="afshopapp" />
</intent-filter>

iOS Deeplink Setup

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

#import <RNAppsFlyer.h>
// Deep linking
// Open URI-scheme for iOS 9 and above
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url options:(NSDictionary *) options {
  [[AppsFlyerAttribution shared] handleOpenUrl:url options:options];
    return YES;
}
// Open URI-scheme for iOS 8 and below
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString*)sourceApplication annotation:(id)annotation {
  [[AppsFlyerAttribution shared] handleOpenUrl:url sourceApplication:sourceApplication annotation:annotation];
  return YES;
}
// Open Universal Links
- (BOOL)application:(UIApplication *)application continueUserActivity:(NSUserActivity *)userActivity restorationHandler:(void (^)(NSArray * _Nullable))restorationHandler {
    [[AppsFlyerAttribution shared] continueUserActivity:userActivity restorationHandler:restorationHandler];
    return YES;
}

Universal Links

Universal Links link between an iOS mobile app and an associate website/domain, such as AppsFlyer’s OneLink domain (xxx.onelink.me). To do so, it is required to:

1. Configure OneLink sub-domain and link to mobile app (by hosting the ‘apple-app-site-association’ file - AppsFlyer takes care of this part in the onelink setup on your dashboard)
2. Configure the mobile app to register approved domains:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
    <dict>
        <key>com.apple.developer.associated-domains</key>
        <array>
            <string>applinks:test.onelink.me</string>
        </array>
    </dict>
</plist>

For more on Universal Links check out the guide here.

URI Scheme

A URI scheme is a URL that leads users directly to the mobile app. When an app user enters a URI scheme in a browser address bar box, or clicks on a link based on a URI scheme, the app launches and the user is deep-linked.

To configure it you will have to:

1. Add a unique url identifier in the URL types entry in the app's info.plist
2. Add URL Scheme as a value.

example of a URL scheme configuration in the info.plist:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
  ...
	<key>CFBundleURLTypes</key>
	<array>
		<dict>
			<key>CFBundleURLName</key>
			<string>YOUR.URL.IDENTIFIER</string>
			<key>CFBundleURLSchemes</key>
			<array>
				<string>YOUR-URL-SCHEME</string>
			</array>
		</dict>
	</array>
	...
</dict>
</plist>
