Unity Error building Android Project : Gradle Daemon

Question

I'm creating a little game on Android and all was alright since today.

I tried to add ads and IAP on my project and now when I try to build my project it gives me this errors : (I tried to upload the screen of my console but it tells me "Error parsing the uploaded files" so sorry)

• File C:\Users\bonel.android\repositories.cfg could not be loaded.

• Unable to find player assembly: D:\Jeux\UNITY\SythwavesJumper\Temp\StagingArea\Data\Managed\UnityEngine.TestRunner.dll

• Starting a Gradle Daemon, 1 incompatible Daemon could not be reused, use --status for details Configure project :launcher WARNING: The option setting 'android.enableR8=false' is deprecated.

• Note: D:\Jeux\UNITY\SythwavesJumper\Library\Bee\Android\Prj\Mono2x\Gradle\unityLibrary\src\main\java\com\unity3d\player\UnityPlayerActivity.java uses or overrides a deprecated API. Note: Recompile with -Xlint:deprecation for details. FAILURE: Build failed with an exception.

What went wrong: Execution failed for task ':launcher:checkDebugDuplicateClasses'. - CommandInvokationFailure: Gradle build failed.

And after it tells me that my build doesn't achieve (obviously). Please could you tell me if you know a solution? Great thanks!

Answer 1

Make sure your target API level is the minimum required for your Android device (Edit > Project Settings > Player), also set your 'managed stripping level' to minimal and add the folllowing into a link.xml config file in your Assets folder or a subdirectory of the assets folder:

<linker>
  <assembly fullname="UnityEngine.TestRunner" preserve="all"/>
</linker>
