Test google signin on Android in development phase

Question

Google signin is always returning signed-out. It always fails when pushing the app on the device using Android studio.

However, when I install the signed app it works.

How can I make google sign in works while we are still developing the app?

Answer 1

At development time, you are probably using your debug key store:

Get the SHA-1 of your debug key cert:

keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android

And register it together your package name in developer console Credentials page as well. (Each pair requires one registration)

You can refer to this post's answer for details: Occured an INTERNAL_ERROR when requestEmail from GoogleSignInOptions Android
