Error:Execution failed for task app:processGoogleAdsDebugGoogleServices

What is app:processGoogleAdsDebugGoogleServices

This error appears if you have bought an app from an app market place such as sellmyapp or Codecanyon and try to compile it in Android Studio by changing the package name.

Every app has a package name such such com.zzz.xxxx. If the app supports Fire base, the developer would have registered it in Firebase database. The developer downloads the config file and add to the source code. Android Studio will compile the source code only if the package name matches with the package name in Firebase config file.

The Execution failed error appears because Android Studio could not match the package name of the app and the package name in the firebase config file.
