Google+ signin - handleSignInResult returns false after customizing signin button

问题

I'm following the sample code given by Google to integrate Google plus with android. https://github.com/googlesamples/google-services/blob/master/android/signin/app/src/main/java/com/google/samples/quickstart/signin/SignInActivity.java

That code sample worked perfectly fine until I added some changes as follows.

GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
 .requestScopes(new Scope(Scopes.PLUS_LOGIN))
 .requestEmail()
 .build();

mGoogleApiClient = new GoogleApiClient.Builder(this)
 .enableAutoManage(this /* FragmentActivity */, this /* OnConnectionFailedListener */)
 .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
 .build();

signinGoogleBtn = (SignInButton) findViewById(R.id.signingoogleBtn);
signinGoogleBtn.setSize(SignInButton.SIZE_STANDARD);
signinGoogleBtn.setScopes(gso.getScopeArray());

I added Google+ scopes to GoogleSignInOptions in order to customize the signin button. Then GoogleSignInResult and handleSignInResult always returns false.

if (requestCode == RC_SIGN_IN) {
        GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
        handleSignInResult(result);

Could anyone please help me to fix this issue?

Hey i was having same problem, i think in your case either you have not put your google-services.json file inside your app folder or you are not running your signed apk file if this the case first sign your apk and then paste this apk file in your mobile and from their open it, i mean don't run your app from android studio because what it does is it does not run signed apk file on mobile device. Hope this works :)
