Fehler bei der Integration von Google bekommen und mit Android in Eclipse

Question

Ich verwende google + Login für meine Anwendung. Erstbenutzer ist angemeldet. Wenn der Benutzer sich abmeldet und sich wieder derselbe Benutzer anmeldet, dann habe ich Plus.PeopleApi.getCurrentPerson(mGoogleApiClient) ist null.

Wie um diesen Fehler zu beheben.

public void onConnected(Bundle connectionHint) {   

    // Reaching onConnected means we consider the user signed in. 
    // Update the user interface to reflect that the user is signed in. 
    // Retrieve some profile information to personalize our app for the 
    // user. 

    Plus.PeopleApi.loadVisible(mGoogleApiClient, null).setResultCallback(null); 
    Person currentUser = Plus.PeopleApi.getCurrentPerson(mGoogleApiClient); 

    String email = Plus.AccountApi.getAccountName(mGoogleApiClient); 

    if (currentUser == null) { 
     Utils.signOutAndDisconnect(mGoogleApiClient); 
     if (isGooglePlusClicked) { 
      isGooglePlusClicked = false; 
      Toast.makeText(
        this, 
        "Google sign-in is not available for now. " 
          + "Please try again later.", Toast.LENGTH_SHORT) 
          .show(); 
     } 
     return; 
    } 

    Log.i(TAG, "g+ onConnected isSignInClicked currentUser=" + currentUser); 
    BaseWebServiceRunner webServiceRunner = new BaseWebServiceRunner(this); 

    Log.i(TAG, "g+ onConnected isGooglePlusClicked value=" + isGooglePlusClicked); 

    if (isGooglePlusClicked) { 
     isGooglePlusClicked = false; 
     if (edit_username.getVisibility() == View.VISIBLE) { 
      User user = new User(); 
      user.setFname(currentUser.getDisplayName()); 
      UserGoogle usergoogle = new UserGoogle(); 
      usergoogle.setAbout_me(currentUser.getAboutMe()); 
      usergoogle.setBirthdate(currentUser.getBirthday()); 
      switch (currentUser.getGender()) { 
      case 1: 
       usergoogle.setGender("FEMALE"); 
       user.setGender("FEMALE");

      default: 
       usergoogle.setGender("OTHER"); 
       user.setGender("OTHER"); 
       break; 
      } 

      Image image = currentUser.getImage(); 
      if (image != null && image.hasUrl()) { 
       // by default the profile url gives 50x50 px image only 
       // we can replace the value with whatever dimension we want 
       // by 
       // replacing sz=X 
       String actualUrl = image.getUrl(); 
       String url = actualUrl.substring(0, actualUrl.length() - 2) 
         + Prefs.SCALE_BITMAP_WIDTH; 
       user.setPicture(url); 
      } 

      usergoogle.setLogin_name(email); 
      user.setGoogle(usergoogle); 
      user.setEmail(email); 
      user.setUsername(email); 
      user.setPassword("123456"); 
      user.setRegister_by(UserLoginType.Google.toString()); 

      user.setAddress1(SharedPreferenceConnector.readString(this, Prefs.ADDRESS_LINE_0, "")); 
      user.setAddress2(SharedPreferenceConnector.readString(this, Prefs.ADDRESS_LINE_1, "")); 
      user.setCity(SharedPreferenceConnector.readString(this, Prefs.CITY_NAME, "")); 
      user.setState(SharedPreferenceConnector.readString(this, Prefs.STATE_NAME, "")); 
      user.setCountry(SharedPreferenceConnector.readString(this, Prefs.COUNTRY_NAME, "")); 

      //    user.setDevice_id(Utility.getDeviceId(this)); 

      UserRegistrationWS registrationWS = new UserRegistrationWS(
        this, user, UserRegistrationType.NEW); 
      UserRegistrationWS[] params = new UserRegistrationWS[1]; 
      params[0] = registrationWS; 
      webServiceRunner.execute(params); 
     } 
    } else { 
     Utils.signOutAndDisconnect(mGoogleApiClient); 
    } 
    gServicesSignInProg = STATE_DEFAULT; 
}
