Answer 1

I have this issue on Unity where I was building for Android. This is what I did to fix this issue. I hope you can take some pointers from this and apply it to your own situation. I'm not really an Android Developer so only have very basic understanding of Gradle.

Weirdly enough in my case this issue "suddenly" started occurring after I made a small code change to a script of a functioning application.

In the Project Settings > Player > Android > Publishing Settings, select Custom Main Gradle Template

Open the file and ensure the following code snippets exists:

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
// Android Resolver Dependencies Start
    implementation 'com.google.android.gms:play-services-location:16+' // Google.XR.ARCoreExtensions.Editor.Internal.ExternalDependencyResolverHelper.RegisterAndroidDependencies
// Android Resolver Dependencies End
**DEPS**}

This snippet was there by default in my case, but should ensure the play services package for location tracking is linked properly.

You can validate it's there by analyzing the apk package after building in Android Studio (Build > Analyze Package). The package will include play services property files and also one of the classes*.dex files will reference com.goog.android.gms.

Hope this helps!
