Execution failed for task ':app:processDebugGoogleServices' Firebase&Android Studio

Question

I want to add Firebase-database to the my Android application and I have got error.

FAILURE: Build failed with an exception.

• What went wrong: Execution failed for task ':app:processDebugGoogleServices'.

  Please fix the version conflict either by updating the version of the google-services plugin (information about the latest version is available at https://bintray.com/android/android-tools/com.google.gms.google-services/) or updating the version of com.google.android.gms to 11.8.0.

• Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

Can someone help me?

Answer 1

change this:

implementation 'com.google.firebase:firebase-database:11.8.0'

to this:

implementation 'com.google.firebase:firebase-database:12.0.1'

All google play services and firebase dependencies need to have the same version number.

This changes starting from version number 15:

Each Maven dependency matching com.google.android.gms:play-services-* and com.google.firebase:firebase-* is no longer required to have the same version number in order to work correctly at build time and at run time.
