I have been following this tutorial to get Google SignOn going: https://developers.google.com/identity/sign-in/android/start-integrating
When I run my application locally with a virtual device it works fine but when I deploy it to my device via debugging or if I generate a signed jar file and copy it manual GoogleSignInResult always returns false with an INTERNAL ERROR message.
I'm struggling since quite a while to be able to use google login when deploying the application via debug to my device. Any help is highly appreciated!
Solution for My Issue:
Where you download the json file you have to copy past the code that you can generate with the java key tool. I totally missed that a few times in a row.
