無法安卓的Facebook登錄後註銷

Question

public void logoutFromFacebook() { 

    mAsyncRunner.logout(this, new RequestListener() { 
     @Override 
     public void onComplete(String response, Object state) { 
      Log.d("Logout from Facebook", response); 
      if (Boolean.parseBoolean(response) == true) { 
       runOnUiThread(new Runnable() { 

        @Override 
        public void run() 
        { 

         Toast.makeText(getApplicationContext(),"LogOut Successfull", Toast.LENGTH_LONG).show(); 
        } 

       }); 

      } 
     } 

     @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) { 
     } 
    }); 
} 

登錄後，如果我點擊退出按鈕無法退出，並再按一次登錄按鈕獲取會話true.How我可以從這裏得到註銷，以便其他用戶可以登錄使用他/她的臉書ID。

Answer 1

For logut use：

import com.facebook.Session; ....

Session.getActiveSession（）。closeAndClearTokenInformation（）;

Answer 2

import com.facebook.Session; 

    private void logout() 
    { 
     // clear any user information 
     mApp.clearUserPrefs(); 

     // find the active session which can only be facebook in my app 
     Session session = Session.getActiveSession(); 

     // run the closeAndClearTokenInformation which does the following 
     // DOCS : Closes the local in-memory Session object and clears any persistent 
     // cache related to the Session. 
     session.closeAndClearTokenInformation(); 

     // return the user to the login screen 
     startActivity(new Intent(getApplicationContext(), LoginActivity.class)); 

     // make sure the user can not access the page after he/she is logged out 
     // clear the activity stack 
     finish(); 
    }
