Answer 1

Have you used google services plugin in classpath also?
If not please write in build.gradle located outside of the app folder
classpath 'com.google.gms:google-services:3.0.0'
I think this will help you ..!!

I faced the same problem and I solved this by uninstalling the app [yourapp.apk] from your device (e.g: your mobile device) and then run react-native run-android again and it worked like a charm.
But Why?
because you've already had the app with the same name installed on your device (mainly because of the reason that you've downloaded it from somewhere -- and now you want to run the test.app which has the same name, so that's why you've faced this error
do not hesitate to ask me any questions if it didn't work for you!
