Code Implementation Google SignIn
suggest change- In your sign-in activity’s onCreate method, configure Google Sign-In to request the user data required by your app.
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN) .requestEmail() .build();
- create a GoogleApiClient object with access to the Google Sign-In API and the options you specified.
mGoogleApiClient = new GoogleApiClient.Builder(this) .enableAutoManage(this /* FragmentActivity */, this /* OnConnectionFailedListener */) .addApi(Auth.GOOGLE_SIGN_IN_API, gso) .build();
- Now When User click on Google signin button call this Function.
private void signIn() { Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient); startActivityForResult(signInIntent, RC_SIGN_IN); }
- implement OnActivityResult to get the response.
@Override public void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); // Result returned from launching the Intent from GoogleSignInApi.getSignInIntent(...); if (requestCode == RC_SIGN_IN) { GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data); handleSignInResult(result); } }
- Last step Handle The Result and get User Data
private void handleSignInResult(GoogleSignInResult result) { Log.d(TAG, "handleSignInResult:" + result.isSuccess()); if (result.isSuccess()) { // Signed in successfully, show authenticated UI. GoogleSignInAccount acct = result.getSignInAccount(); mStatusTextView.setText(getString(R.string.signed_in_fmt, acct.getDisplayName())); updateUI(true); } else { // Signed out, show unauthenticated UI. updateUI(false); } }
