Include Android

Prerequisites
Minimum SDK version	21
Compile SDK version	34
Gradle	6.7.1+
Android Gradle plugin	4.2.2+

Disable Unreal Engine's built-in AdMob support

The CAS plugin automatically performs all configurations for AdMob in mediation integration.

Navigate to the Editor > Project Settings > Platform > Android > Google Play Services section and disable the option:

• Include AdMob support for ads

Additionally, use the advertising management functions from CAS Mobile Ads, not the built-in functions for AdMob.

Warning

Be cautious, as some Blueprint Nodes have identical names: Show Interstitial Ad, Show Ad Banner.
You should exclusively use nodes from the CAS Mobile Ads category.

Upgrade the Gradle wrapper

To select the Gradle version, navigate to the directory for your version of the Unreal Engine and follow the file path.

Engine/Build/Android/Java/gradle/gradle/wrapper/gradle-wrapper.properties

Change the distributionUrl property to the desired version.

distributionUrl=https\://services.gradle.org/distributions/gradle-6.7.1-all.zip

Note

If your UE is already using a newer version of Gradle than 6.7.1, you don't need to do anything further. The Android Gradle plugin version will also be at least 4.2.2.

Upgrade the Android Gradle plugin

To select the Android Gradle plugin version, navigate to the directory for your version of the Unreal Engine and follow the file path.

Engine/Build/Android/Java/gradle/build.gradle

Change the line with com.android.tools.build:gradle to the desired version.

buildscript {
    repositories { ... }
    dependencies {
        classpath 'com.android.tools.build:gradle:4.2.2'
    }
    ...
}

Unreal Engine 4 compatibility for API 34

The AppCache API is no longer supported, so its use must be removed from the engine java script.

Navigate to the directory for your version of the Unreal Engine and follow the file path.

Engine/Build/Android/Java/src/com/epicgames/ue4/WebViewControl.java

Remove (comment) the following lines of code:

viewer.getSettings().setAppCacheMaxSize(1024*1024*8);
viewer.getSettings().setAppCachePath("/data/data/com.your.package.appname/cache"‌​);
viewer.getSettings().setAppCacheEnabled(true);

Unreal Engine 4 compatibility for API 32

Applications which has an activity, activity alias, service or broadcast receiver with intent filter, must explicitly declare the android:exported attribute.

android:exported="true"
