Hello Alefe,

That version of Gradle that you’re using will cause issues with Android builds. I recommend sticking to the recommended 6.7.1.

Please have a look at this forum post for more information: How to Resolve Gradle Build Error: "The option setting 'android.enableR8=false' is deprecated..."

If the information on the forum post does not resolve your issue, please reply back here, not on the guide itself :slight_smile:

Yep, use 6.7.
I also got 7.2 working but not 8+

4

I’ve already followed the steps of the topic. I’m still getting this error(the same error of my edit):

  • What went wrong:
    Execution failed for task ‘:launcher:checkReleaseAarMetadata’.

A failure occurred while executing com.android.build.gradle.internal.tasks.CheckAarMetadataWorkAction
The minCompileSdk (31) specified in a
dependency’s AAR metadata (META-INF/com/android/build/gradle/aar-metadata.properties)

I updated my Android SDK to API level 31 and now the build is complete, but when I installed it on my device, I was unable to run the app. Any idea why? The only options I have is to uninstall the app or force stop (this option appears but I can’t press it).The application does not appear as an executable. I can only see it in device settings.

6

Could it be my AndroidManifest? I change it to be exactly like the one on this guide: Building ARDK Apps for Android — Niantic Lightship Augmented Reality Developer Kit release-2.5.2 documentation

7

When i use the default AndroidManifest from unity, i got a new error:

Execution failed for task ‘:unityLibrary:processReleaseManifest’.

A failure occurred while executing com.android.build.gradle.tasks.ProcessLibraryManifest$ProcessLibWorkAction
Manifest merger failed : Apps targeting Android 12 and higher are required to specify an explicit value for android:exported when the corresponding component has an intent filter defined. See <activity>  |  Android Developers for details.

I was successful in building the application. Now I have a new problem. I will open a new topic
