Integration

This page shows you how to download, import, and configure the AppLovin MAX SDK.

Download the Latest SDK

You can download the SDK through Gradle as a dependency. If you prefer to integrate manually, follow the instructions here.

The SDK requires the minSdkVersion to be 19 or above.

To receive release updates, subscribe to the AppLovin Android MAX SDK GitHub repository.

Gradle

Add the following to your app-level build.gradle file:

Groovy

repositories {
  google()
  mavenCentral()
  ⋮
}
dependencies {
  implementation 'com.applovin:applovin-sdk:+'
  ⋮
}

Kotlin

repositories {
  google()
  mavenCentral()
  ⋮
}
dependencies {
  implementation("com.applovin:applovin-sdk:+")
  ⋮
}

ProGuard Rules

If you use ProGuard, note that the AppLovin MAX SDK and adapters come bundled with the required ProGuard rules in the AARs. Therefore, you do not need to add any additional ProGuard rules to your project.

Note

The SDK collects the Google Advertising ID. This requires the Android Advertising ID (AAID) module (com.google.android.gms:play-services-ads-identifier). See Google Play services dependencies.

Integrate Custom SDK Adapters

AppLovin Exchange (ALX) supports a custom adapter for LinkedIn. Integration instructions are below, and more information can be found here.

To install the adapter, add the following to your app-level build.gradle file:

Groovy

dependencies {
  implementation 'com.applovin.dsp:linkedin-adapter:+'
}

Kotlin

dependencies {
  implementation ("com.applovin.dsp:linkedin-adapter:+")
}

Enable Ad Review

To enable the MAX Ad Review service, add the following to your build.gradle files:

Additions to Root-Level build.gradle File

Groovy

buildscript {
  repositories {
    maven { url 'https://artifacts.applovin.com/android' }
  }
  dependencies {
    classpath "com.applovin.quality:AppLovinQualityServiceGradlePlugin:+"
  }
}

Kotlin

buildscript {
  repositories {
    maven { url = uri("https://artifacts.applovin.com/android") }
  }
  dependencies {
    classpath ("com.applovin.quality:AppLovinQualityServiceGradlePlugin:+")
  }
}

Additions to App-Level build.gradle File

Groovy

apply plugin: 'applovin-quality-service'
applovin {
  apiKey "«ad-review-key»"
}

Kotlin

plugins {
  id("applovin-quality-service")
}
applovin {
  apiKey = "«ad-review-key»"
}

You can find your Ad Review Key in the Account > General > Keys section of the AppLovin dashboard.

Initialize the SDK

Create the SDK Initialization Configuration

Before you initialize the SDK, create an initialization configuration object for the SDK. This object allows you to configure the properties that the SDK will initialize with. These initialization properties are immutable, with the exception of AppLovinSdkSettings which contains mutable properties that can be changed during the lifetime of the app.

Java

// Create the initialization configuration
AppLovinSdkInitializationConfiguration initConfig = AppLovinSdkInitializationConfiguration.builder( "«SDK-key»" )
                 .setMediationProvider( AppLovinMediationProvider.MAX )
// Perform any additional configuration/setting changes
                 .build();

Kotlin

// Create the initialization configuration
val initConfig = AppLovinSdkInitializationConfiguration.builder("«SDK-key»")
                 .setMediationProvider(AppLovinMediationProvider.MAX)
// Perform any additional configuration/setting changes
                 .build()

You can find your SDK key in the Account > General > Keys section of the AppLovin dashboard.

Initialize the SDK

Initialize the AppLovin SDK with the initialization configuration object as early as possible (for example, in the onCreate() of the launch activity or Application class). This maximizes how much time the SDK has to cache mediated networks’ ads, which results in a better user experience.

Java

public class MainActivity extends Activity
{
  protected void onCreate(Bundle savedInstanceState)
  {
    // Create the initialization configuration
    AppLovinSdkInitializationConfiguration initConfig = AppLovinSdkInitializationConfiguration.builder( "«SDK-key»" )
                     .setMediationProvider( AppLovinMediationProvider.MAX )
                     .build();

    // Initialize the SDK with the configuration
    AppLovinSdk.getInstance( this ).initialize( initConfig, new AppLovinSdk.SdkInitializationListener()
    {
      @Override
      public void onSdkInitialized(final AppLovinSdkConfiguration sdkConfig)
      {
        // Start loading ads
      }
    } );
  }
}

Kotlin

class MainActivity : Activity()
{
  override fun onCreate(savedInstanceState: Bundle?)
  {
    // Create the initialization configuration
    val initConfig = AppLovinSdkInitializationConfiguration.builder("«SDK-key»")
                     .setMediationProvider(AppLovinMediationProvider.MAX)
                     .build()

    // Initialize the SDK with the configuration
    AppLovinSdk.getInstance(this).initialize(initConfig) { sdkConfig ->
      // Start loading ads
    }
  }
}

Example

Below is a sample integration:

Java

// Create the initialization configuration
AppLovinSdkInitializationConfiguration initConfig = AppLovinSdkInitializationConfiguration.builder( "«SDK-key»" )
    .setMediationProvider( AppLovinMediationProvider.MAX )
    .setSegmentCollection( MaxSegmentCollection.builder()
                             .addSegment( new MaxSegment( 849, Arrays.asList( 1, 3 ) ) )
                             .build() )
    .build();

// Configure the SDK settings if needed before or after SDK initialization.
val settings = AppLovinSdk.getInstance( this ).getSettings();
settings.setUserIdentifier( "«user-ID»" );
settings.setExtraParameter( "uid2_token", "«token-value»" );
settings.getTermsAndPrivacyPolicyFlowSettings().setEnabled( true );
settings.getTermsAndPrivacyPolicyFlowSettings().setPrivacyPolicyUri( Uri.parse( "«https://your-company-name.com/privacy-policy»" ) );
settings.getTermsAndPrivacyPolicyFlowSettings().setTermsOfServiceUri( Uri.parse( "«https://your-company-name.com/terms-of-service»" ) );

// Initialize the SDK with the configuration
AppLovinSdk.getInstance( this ).initialize( initConfig, new AppLovinSdk.SdkInitializationListener()
{
  @Override
  public void onSdkInitialized(final AppLovinSdkConfiguration sdkConfig)
  {
    // Start loading ads
  }
} );

Kotlin

// Create the initialization configuration
val initConfig = AppLovinSdkInitializationConfiguration.builder("«SDK-key»")
    .setMediationProvider(AppLovinMediationProvider.MAX)
    .setSegmentCollection(MaxSegmentCollection.builder()
                            .addSegment(MaxSegment(849, listOf(1, 3)))
                            .build()
    )
    .build()

// Configure the SDK settings if needed before or after SDK initialization.
val settings = AppLovinSdk.getInstance(this).settings
settings.userIdentifier = "«user-ID»"
settings.setExtraParameter("uid2_token", "«token-value»")
settings.termsAndPrivacyPolicyFlowSettings.apply {
  isEnabled = true
  privacyPolicyUri = Uri.parse("«https://your-company-name.com/privacy-policy»")
  termsOfServiceUri = Uri.parse("«https://your-company-name.com/terms-of-service»")
}

// Initialize the SDK with the configuration
AppLovinSdk.getInstance(this).initialize(initConfig) { sdkConfig ->
  // Start loading ads
}
