  <pre><code>protected void signIn() {
      Set&lt;Scope&gt; requiredScopes = new HashSet&lt;&gt;(2);
      requiredScopes.add(Drive.SCOPE_FILE);
      requiredScopes.add(Drive.SCOPE_APPFOLDER);
      GoogleSignInAccount signInAccount = GoogleSignIn.getLastSignedInAccount(this);
      if (signInAccount != null &amp;&amp; signInAccount.getGrantedScopes().containsAll(requiredScopes)) {
          initializeDriveClient(signInAccount);
      } else {
          GoogleSignInOptions signInOptions =
                  new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
                          .requestScopes(Drive.SCOPE_FILE)
                          .requestScopes(Drive.SCOPE_APPFOLDER)
                          .build();
          GoogleSignInClient googleSignInClient = GoogleSignIn.getClient(this, signInOptions);
          startActivityForResult(googleSignInClient.getSignInIntent(), REQUEST_CODE_SIGN_IN);
      }
  }
  @Override
  protected void onActivityResult(int requestCode, int resultCode, Intent data) {
      super.onActivityResult(requestCode, resultCode, data);
      switch (requestCode) {
          case REQUEST_CODE_SIGN_IN:
              if (resultCode != RESULT_OK) {
                  // Sign-in may fail or be cancelled by the user. For this sample, sign-in is
                  // required and is fatal. For apps where sign-in is optional, handle
                  // appropriately
                  Log.e(TAG, "Sign-in failed.");
                  finish();
                  return;
              }
  
              Task&lt;GoogleSignInAccount&gt; getAccountTask =
                      GoogleSignIn.getSignedInAccountFromIntent(data);
              if (getAccountTask.isSuccessful()) {
                  initializeDriveClient(getAccountTask.getResult());
              } else {
                  Log.e(TAG, "Sign-in failed.");
                  finish();
              }
              break;
      }
      super.onActivityResult(requestCode, resultCode, data);
  }
