Android程序连接Facebook : LoginActivity has leaked window

Question

这是 Facebook 自己提供的基本程序 - 将 Android 应用程序连接到 Facebook:但我似乎得到一个错误:

Activity com.Facebook.LoginActivity has leaked window com.android.internal.policy.impl.PhoneWindow@DecorView@40512630 最初添加在这里:

尝试了以下方法:

• 我已经验证了我的 keyHash。
• 我已经验证了我的 Android.xml
• 我在论坛上寻找更多意见。

有什么建议吗？？？

主要 Activity :

package com.example.facebookconnectionapp;

import com.facebook.Request;
import com.facebook.Response;
import com.facebook.Session;
import com.facebook.SessionState;
import com.facebook.model.GraphUser;

import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.util.Log;
import android.view.Menu;
import android.widget.TextView;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Log.i("Facebook Activity", "Before opening session");

        Session.openActiveSession(this, true, new Session.StatusCallback() {

            @Override
            public void call(Session session, SessionState state, Exception exception) {
                // TODO Auto-generated method stub

                Log.i("Facebook Activity", "Checking if session open");

                if(session.isOpened()){

                    Log.i("Facebook Activity", "Session is open");
                    Request.executeMeRequestAsync(session, new Request.GraphUserCallback() {

                        @Override
                        public void onCompleted(GraphUser user, Response response) {
                            // TODO Auto-generated method stub

                            Log.i("Facebook Activity", "Inside GraphCallback");

                            TextView textView = (TextView) findViewById(R.id.textView1);
                            textView.setText(user.getUsername());
                        }
                    });
                } else {

                    Log.i("Facebook Activity", "Session not open");
                }

            }
        });
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        // TODO Auto-generated method stub
        super.onActivityResult(requestCode, resultCode, data);

        Session.getActiveSession().onActivityResult(this, requestCode, resultCode, data);
    }

}
