无法从Facebook会话登出

Question

我创建了一个facebook集成应用程序。我可以正确登录和注销，而且没有任何问题，并且当我登录并关闭应用程序时，然后重新打开它，我可以正确注销。但我的问题是当我登录然后从Eclipse运行应用程序我无法注销。它显示错误。

@Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
      facebook = new Facebook(APP_ID); 
      mAsyncRunner = new AsyncFacebookRunner(facebook); 

     sharePref = getPreferences(MODE_PRIVATE); 
     facebook.setAccessToken(sharePref.getString(ACCESS_TOKEN, null)); 
     facebook.setAccessExpires(sharePref.getLong(EXPIRE_SESSION, 0)); 

    buttonLogin.setOnClickListener(new OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       loginToFacebook(); 
      } 
     }); 

buttonLogout.setOnClickListener(new OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       logoutFacebook(); 
      } 
     }); 
} 

public void loginToFacebook() { 


     if (!facebook.isSessionValid()) { 
      facebook.authorize(this, PERMISSIONS, Facebook.FORCE_DIALOG_AUTH, 
        new DialogListener() { 
         @Override 
         public void onFacebookError(FacebookError e) { 
         } 

         @Override 
         public void onError(DialogError e) { 
         } 

         @Override 
         public void onComplete(Bundle values) { 
          SharedPreferences.Editor editor = sharePref.edit(); 
          editor.putString(ACCESS_TOKEN, 
            facebook.getAccessToken()); 
          editor.putLong(EXPIRE_SESSION, 
            facebook.getAccessExpires()); 
          editor.commit(); 
         } 

         @Override 
         public void onCancel() { 
         } 
        }); 
     } else { 
      Toast.makeText(getApplicationContext(), "You Already Login", 
        Toast.LENGTH_SHORT).show(); 
     } 
    } 
protected void logoutFacebook() { 
     if (facebook.isSessionValid()) { 
      mAsyncRunner.logout(this, 
        new RequestListener() { 
         @Override 
         public void onComplete(String response, Object state) { 
          Log.d("Logout from Facebook", response); 
          if (Boolean.parseBoolean(response) == true) { 
           Log.e("Logout from Facebook", "Great"); 
          } 
         } 

         @Override 
         public void onIOException(IOException e, Object state) { 

         } 

         @Override 
         public void onFileNotFoundException(
           FileNotFoundException e, Object state) { 
         } 

         @Override 
         public void onMalformedURLException(
           MalformedURLException e, Object state) { 
         } 

         @Override 
         public void onFacebookError(FacebookError e, 
           Object state) { 
         } 
        }); 
     } else { 
      Toast.makeText(getApplicationContext(), "Login First", 
        Toast.LENGTH_SHORT).show(); 
     } 
    }

Answer 1

试试这个..

删除下面从mainactivity线..

sharePref = getPreferences(MODE_PRIVATE); 
     facebook.setAccessToken(sharePref.getString(ACCESS_TOKEN, null)); 
     facebook.setAccessExpires(sharePref.getLong(EXPIRE_SESSION, 0)); 

并在下面添加行内的登录功能

mPrefs = getPreferences(MODE_PRIVATE); 
      String access_token = mPrefs.getString("access_token", null); 
      long expires = mPrefs.getLong("access_expires", 0); 

      if (access_token != null) { 
       facebook.setAccessToken(access_token); 
Toast.makeText(getApplicationContext(), "You Already Login", 
        Toast.LENGTH_SHORT).show(); 
      } 

      if (expires != 0) { 
       facebook.setAccessExpires(expires); 
Toast.makeText(getApplicationContext(), "You Already Login", 
        Toast.LENGTH_SHORT).show(); 
      }
