Google login always fails at GoogleSignInResult

Question

I need your help ... I have no idea!

I don’t understand why he fails every time.

• I created OAuth 2.0 client identifiers.
• I generated and moved the google-services.json folder to ./app .
• The Google Cloud Console supports all Google APIs where they are activated.

Check out and if something hurts you ... Go on!

Yours faithfully

Answer 1

From your code replace

 gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN) .requestEmail() .build(); 

with this:

 gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN) .requestIdToken("web client id from console.developers.google.com for the app") .requestEmail() .build(); 

Hope this helps someone. Also, using firebase Signin is much easier. Check out the link . Thanks

For me, this happened when the application was signed with the wrong certificate, the SHA-1 certificate must be registered in the Google console.

For the debug build option, you can also add your debug certificate to the Google console or configure build.gradle for the debug option to use the same certificate that you registered in the console.
