   GoogleSignInClient mGoogleSignInClient;
       private void setupAuthorization() {
           GoogleSignInOptions signInOptions =
                   new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
                           .requestEmail() // add it if you want to user email 
                           .requestScopes(Drive.SCOPE_FILE)
                           .build();
           mGoogleSignInClient = GoogleSignIn.getClient(this, signInOptions);
           mGoogleSignInClient.silentSignIn().addOnSuccessListener(googleSignInAccount -> {googleSignInAccount.getEmail()}).addOnFailureListener(e -> {});
   }
   

2. If you want to get email and name after signing in

   @Override protected void onActivityResult(final int requestCode, final int resultCode, final Intent data) { super.onActivityResult(requestCode, resultCode, data); switch (requestCode) { case REQUEST_CODE_DRIVE_SIGN_IN: Log.i(TAG, "Sign in request code"); // Called after user is signed in. if (resultCode == RESULT_OK) { Log.i(TAG, "Signed in successfully."); // Use the last signed in account here since it already have a Drive scope. GoogleSignInAccount googleSignInAccount = GoogleSignIn.getLastSignedInAccount(this); googleSignInAccount.getEmail(); mDriveClient = Drive.getDriveClient(this, GoogleSignIn.getLastSignedInAccount(this)); // Build a drive resource client. mDriveResourceClient = Drive.getDriveResourceClient(this, GoogleSignIn.getLastSignedInAccount(this)); } break;}}
