Android 获取facebook事件

我正在尝试获取facebook事件列表，其中包含事件主机名称和开始时间。我正在使用android的官方facebook sdk

但由于某些原因，每当我在应用程序中单击get event时，它都会加载，然后不检索任何数据

任何帮助都会很棒的我已经在这上面呆了好几个星期了

我的代码：

public static final String APP_ID = "";

private static final String[] PERMISSIONS =
    new String[]{ "offline_access", "read_stream", 
            "publish_stream","create_event","user_events","friends_events",
            "publish_checkins", "friends_checkins","read_friendlists" };

private TextView mText;
private Handler mHandler = new Handler();
private ProgressDialog mSpinner;
private final ArrayList<Events> events = new ArrayList<Events>();
private EventsArrayAdapter eventsArrayAdapter;
private ListView listView;
private Facebook mFacebook;
private AsyncFacebookRunner mAsyncRunner;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // Make sure the app client_app has been set
    if (APP_ID == null) {
        Util.showAlert(this,
        "Warning", "Facebook Applicaton ID must be set...");
    }

    // Initialize the content view
    setContentView(R.layout.main);
    // Get the status text line resource
    mText = (TextView) workdammit.this.findViewById(R.id.txt);

    // Setup the ListView Adapter that is loaded when selecting "get events"
    listView = (ListView) findViewById(R.id.eventsview);
    eventsArrayAdapter = new EventsArrayAdapter(this, R.layout.rowlayout, events);
    listView.setAdapter(eventsArrayAdapter);

    // Define a spinner used when loading the events over the network
    mSpinner = new ProgressDialog(listView.getContext());
    mSpinner.requestWindowFeature(Window.FEATURE_NO_TITLE);
    mSpinner.setMessage("Loading...");

    // Initialize the Facebook session
    mFacebook = new Facebook(APP_ID);
    mAsyncRunner = new AsyncFacebookRunner(mFacebook);

有什么进展吗？也许你可以把代码最小化一点？将问题定位到特定区域？人们更可能会提供帮助。你的
