Аутентификация с помощью google

Question

Основано на this Я пытаюсь auth с google. Но генерируется исключение GoogleAuthException, а сообщение - «BadUsername». Это меня смущает, так как я выбираю адрес электронной почты/имя пользователя для учетной записи. Кто-нибудь понял, что я делаю неправильно?

public class MainActivity extends Activity implements MainFragment.OnFragmentInteractionListener { 
    private static final String TAG = MainActivity.class.getSimpleName(); 
    static final int REQUEST_CODE_PICK_ACCOUNT = 1000; 
    String mEmail; // Received from newChooseAccountIntent(); passed to getToken() 
    private static final String SCOPE = 
      "oauth2:https://www.googleapis.com/auth/userinfo.profile"; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     ... 
     pickUserAccount(); 
    } 

    private void pickUserAccount() { 
     String[] accountTypes = new String[]{"com.google"}; 
     Intent intent = AccountPicker.newChooseAccountIntent(null, null, 
       accountTypes, false, null, null, null, null); 
     startActivityForResult(intent, REQUEST_CODE_PICK_ACCOUNT); 
    } 

    @Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
     if (requestCode == REQUEST_CODE_PICK_ACCOUNT) { 
      // Receiving a result from the AccountPicker 
      if (resultCode == RESULT_OK) { 
       mEmail = data.getStringExtra(AccountManager.KEY_ACCOUNT_NAME); 
       // With the account name acquired, go get the auth token 
       Toast.makeText(this, mEmail, Toast.LENGTH_SHORT).show(); 
       ConfirmEmailTask confirmEmailTask = new ConfirmEmailTask(this, SCOPE, mEmail); 
       confirmEmailTask.execute(); 

      } else if (resultCode == RESULT_CANCELED) { 
       // The account picker dialog closed without selecting an account. 
       // Notify users that they must pick an account to proceed. 
//    Toast.makeText(this, R.string.pick_account, Toast.LENGTH_SHORT).show(); 
      } 
     } 
     // Later, more code will go here to handle the result from some exceptions... 
    } 

    public class ConfirmEmailTask extends AsyncTask<Void, Void, String> { 
     Activity mActivity; 
     String mScope; 
     String mEmail; 

     ConfirmEmailTask(Activity activity, String name, String scope) { 
      this.mActivity = activity; 
      this.mScope = scope; 
      this.mEmail = name; 
     } 

     /** 
     * Executes the asynchronous job. This runs when you call execute() 
     * on the AsyncTask instance. 
     */ 
     @Override 
     protected String doInBackground(Void... params) { 
      try { 
       String token = fetchToken(); 
       if (token != null) { 
        return token; 
        // Insert the good stuff here. 
        // Use the token to access the user's Google data. 
//     Toast.makeText(mActivity, token, Toast.LENGTH_SHORT).show(); 
       } 
      } catch (IOException e) { 
       // The fetchToken() method handles Google-specific exceptions, 
       // so this indicates something went wrong at a higher level. 
       // TIP: Check for network connectivity before starting the AsyncTask. 
      } 
      return null; 
     } 

     /** 
     * Gets an authentication token from Google and handles any 
     * GoogleAuthException that may occur. 
     */ 
     protected String fetchToken() throws IOException { 
      try { 
       return GoogleAuthUtil.getToken(mActivity, mEmail, mScope); 
      } catch (UserRecoverableAuthException userRecoverableException) { 
       Log.d(TAG, "error"); 
       // GooglePlayServices.apk is either old, disabled, or not present 
       // so we need to show the user some UI in the activity to recover. 
//    mActivity.handleException(userRecoverableException); 
      } catch (GoogleAuthException fatalException) { 
       // Some other type of unrecoverable exception has occurred. 
       // Report and log the error as appropriate for your app. 
       Log.d(TAG, fatalException.getMessage()); 
      } 
      return null; 
     } 

     @Override 
     protected void onPostExecute(String result) { 
      Toast.makeText(mActivity, result, Toast.LENGTH_SHORT).show(); 
     } 
    } 
}

Answer 1

Только для справки.

Проблема здесь заключается в том, что вы передаете неправильно аргументы в этом:

ConfirmEmailTask confirmEmailTask = new ConfirmEmailTask(this, SCOPE, mEmail); 

Конструктор класса определяется как

ConfirmEmailTask(Activity activity, String name, String scope) { 
     this.mActivity = activity; 
     this.mScope = scope; 
     this.mEmail = name; 
} 

Так изменить порядок следования параметров в одном из них.
