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.
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
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.
Navigate to the Editor > Project Settings > Platform > Android > Advanced APK Packaging section and add Extra Tags for UE4 GameActivity <activity> node:
android:exported="true"
