title: Credential setSelectedAccountName null
body: <p>I am trying to ask users to select their google account here. After I use the "setSelectedAccoutName" method, i try to print out the selected account name which returns null. I am 100% sure that accountName is not null. So does anyone know why mCredential.getSelectedAccountName is null?   </p>
  
  <pre><code> private void pickContact() {
  
      AccountManager accountManager = AccountManager.get(getActivity().getApplicationContext());
      Account[] accounts = accountManager.getAccountsByType(null);
      Intent intent = AccountPicker.newChooseAccountIntent(null, null,
              new String[]{"com.google"},
              false, null, null, null, null);
  
      startActivityForResult(intent, 23);
  }
  
  @Override
  public void onActivityResult(int requestCode, int resultCode, Intent data) {
      System.out.println("hi");
      if (requestCode == 23) {
          if (resultCode == Activity.RESULT_OK) {
              Bundle bundle = data.getExtras();
              String accountName = bundle.getString(AccountManager.KEY_ACCOUNT_NAME);
              System.out.println(accountName);
              if (accountName != null) {
                  mCredential.setSelectedAccountName(accountName);
                  System.out.println(mCredential.getSelectedAccountName());
                  getResultsFromApi();
              } else {
                  pickContact();
              }
  
          }
      }
  }
