Install SDK

Before you begin

You need Android Studio to follow along with these guides.

Installing the Android SDK

Install the Android SDK using your preferred method: Via Gradle, or manually.

Install using Gradle

Step 1: Declare repositories
In the Project build.gradle file, declare the mavenCentral repository:

// ...
repositories {
   mavenCentral()
}
/// ...

Step 2: Add dependencies
In the application build.gradle file, add the latest Android SDK package:

dependencies {
    // Get the latest version from https://mvnrepository.com/artifact/com.appsflyer/af-android-sdk
    implementation 'com.appsflyer:af-android-sdk:<<HERE_LATEST_VERSION>>'
    // For example
    // implementation 'com.appsflyer:af-android-sdk:6.12.1>> 
}

Manual install

Setting required permissions

Add the following permissions to AndroidManifest.xml in the manifest section:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    package=YOUR_PACKAGE_NAME>

      <uses-permission android:name="android.permission.INTERNET" />
      <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

      ...

</manifest>

The AD_ID permission

In early 2022, Google announced a change to the behavior of Google Play Services and fetching of the Android Advertising ID. According to the announcement, apps targeting Android 13 (API 33) and above must declare a Google Play services normal permission in their AndroidManifest.xml file in order to get access to the device’s Advertising ID.

Starting V6.8.0, the SDK adds the AD_ID permission automatically.

📘

Note

• If your app participates in the Designed for Families program:
  • If using SDK V6.8.0 and above, you should Revoke the AD_ID permission.
  • If using SDK older than V6.8.0, don't add this permission to your app.
• For apps that target API level 32 (Android 12L) or older, this permission is not needed.

Apps that use SDK versions older than V6.8.0 and target Android 13 (API 33) and above must manually include the permission in their AndroidManifest.xml to have access to the Advertising ID:

<uses-permission android:name="com.google.android.gms.permission.AD_ID" />

Revoking the AD_ID permission

According to Google’s Policy, apps that target children must not transmit the Advertising ID.

When using SDK V6.8.0 and above, children apps targeting Android 13 (API 33) and above must prevent the permission from getting merged into their app by adding a revoke declaration to their Manifest:

<uses-permission android:name="com.google.android.gms.permission.AD_ID"
 tools:node="remove"/>

For more information, see Google Play Services documentation.

ProGuard rules

Optional
If you are using ProGuard and you encounter a warning regarding our AFKeystoreWrapper class, then add the following code to your proguard-rules.pro file:

AppsFlyer SDK ProGuard rules

-keep class com.appsflyer.** { *; }
-keep class kotlin.jvm.internal.** { *; }

Adding store referrer libraries

The AppsFlyer SDK supports several store referrer libraries. Using a store referrer improves attribution accuracy.

You only need to add the referrer dependency, the SDK takes care of the rest.

Google Play Install Referrer

Add the following dependency to your build.gradle:

dependencies {
    // ...
    implementation "com.android.installreferrer:installreferrer:2.2"
}

Google Play Install Referrer ProGuard rules

-keep public class com.android.installreferrer.** { *; }

Meta Install Referrer

Meta install referrer allows AppsFlyer to receive ad campaign metadata from a device’s local storage.

Meta Install Referrer basic flow

The basic flow of the Meta install referrer mechanism is as follows:

1. Once the SDK initializes, it uses the app's Facebook App ID to make a request to the Meta Content Provider API, retrieving the stored metadata from the Facebook app.
2. AppsFlyer SDK sends the install event, along with the attribution data, to the AppsFlyer servers.

Prerequisites

To support the Meta install referrer, the following is required:

• SDK: Integrate with Android SDK version 6.12.6 or higher.
• Facebook App Version: Users must have version 428.x.x or above installed on their device.
• Instagram App Version: Users must have version 296.x.x or above installed on their device.

Configure Meta Install Referrer Support

To enable Meta install referrer support make the Facebook App ID available to the SDK by adding it to the AndroidManifest.xml. This can be done either when integrating the Facebook SDK with the app or when integrating the AppsFlyer SDK with the app.

With Facebook SDK integrated

Refer to Facebook’s official guide to learn how to add the Facebook App ID to AndroidManifest.xml. The SDK will read the Facebook App ID from the meta-data tag.

Without Facebook SDK integration

Include the following tag in AndroidManifest.xml 

<meta-data android:name="com.appsflyer.FacebookApplicationId" android:value="@string/facebook_application_id" />

Include in your strings.xml file:

<string name="facebook_application_id" translatable="false"><YOUR_FACEBOOK_APP_ID></string>

Xiaomi GetApps store referrer

V6.9.0
Add the following dependency to your build.gradle:

dependencies {
  // ...
  implementation "com.miui.referrer:homereferrer:1.0.0.6"
}

Xiaomi GetApps store referrer ProGuard rules

-keep public class com.miui.referrer.** {*;}

📘

Note

Huawei and Samsung store referrers are supported out-of-the-box starting SDK V6.1.1 and do not require any additional integration.

Known issues

Backup rules

If you add android:fullBackupContent="true" inside the tag in the AndroidManifest.xml, you might get the following error:

Manifest merger failed : Attribute application@fullBackupContent value=(true)

To fix this error, add tools:replace="android:fullBackupContent" in the <application> tag in the AndroidManifest.xml file.

If you have your own backup rules specified (android:fullBackupContent="@xml/my_rules"), in addition to the instructions above, please merge them with AppsFlyer rules manually by adding the following rule:

<full-backup-content>
    ...//your custom rules
    <exclude domain="sharedpref" path="appsflyer-data"/>
</full-backup-content>

Missing resource files

SDK V5
If you are using Android SDK V5 and above, make sure that in the APK file, in addition to the classes.dex and resources files, you also have a com > appsflyer > internal folder with files a- and b- inside.
Note: Before SDK 5.3.0, file names are a. and b.

Check that you have the required files by opening your APK in Android Studio:

If those files are missing, the SDK can't make network requests to our server, and you need to contact your CSM or support.

Boot Complete

If your app listens for LOCKED_BOOT_COMPLETED, make sure that all interactions with the SDK are initiated from the launcher activity. This precaution prevents the SDK from crashing when attempting to access SharedPreferences on a device that is still locked.
