我正在为GoogleMaps V2创建MarkerDemo的自定义实现.我有一个奇怪的错误,我将LatLng值提供给LatLngBounds.Builder实例,然后将其作为变量传递给.build.当我通过Eclipse在调试模式下运行应用程序时,Map会加载.当我通过Eclipse正常运行时,会抛出一个带有"no included points"的IllegalStateException作为消息.有人可以帮忙吗？

这是一些协助的代码.

public class MyActivity extends android.support.v4.app.FragmentActivity
        implements OnMarkerClickListener, OnInfoWindowClickListener,
        OnMarkerDragListener {

    private HashMap<DataItem, ArrayList<DataItem>> mUserLocations = new
             HashMap<DataItem, ArrayList<DataItem>>();
    private ArrayList<DataItem> mFeedData;
    private NetworkingHandler mHandler = new NetworkingHandler("tag");
    private GoogleMap mMap;
    private final String DOWNLOAD_USER_LOCATIONS_URL =
               "http://www.myfeedurllocation.com/page.php";

    @Override
    public void onCreate(Bundle savedBundleInstance) {
        super.onCreate(savedBundleInstance);
        setContentView(R.layout.activity_myactivitylayout);
        downloadUserLocations();
        setUpMapIfNeeded();
    }

    @Override
    protected void onResume() {
        super.onResume();
        setUpMapIfNeeded();
    }

    private void setUpMapIfNeeded() {
        // Do a null check to confirm that we have not already instantiated the
        // map. …
