Question

我＆＃39;尝试使用Android Studio在Android上开发地图应用程序。经过一些操作后，我面临着内存不足的异常...

我有一个抽屉活动，可以在两个片段之间切换：

void StartFragment(int position)
    {
        FragmentTransaction transaction = getFragmentManager().beginTransaction();
        Fragment newFragment = null;
        switch(position){
            case(1):
                newFragment = new MissionFragment();
                transaction.replace(R.id.frame_container, newFragment);
                break;
            case(0):
            default:
                newFragment = new MapFragment();
                transaction.replace(R.id.frame_container, newFragment);
                break;
        }
        if (newFragment != null) {
            transaction.addToBackStack(null);
            transaction.commit();
            mCurrentFragment = position;
        }

    }

地图片段的构造如下：

public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {

        // Inflate the layout for this fragment
        LinearLayout rl = (LinearLayout) inflater.inflate(R.layout.fragment_map, container, false);
        map = (MapView) rl.findViewById(R.id.map);

        return rl;

    }

和此：

public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);

    mContext = getActivity();

    mMissionDataModel = MissionDataModel.getInstance(mContext);

    map.setTileSource(TileSourceFactory.MAPNIK);
    map.setBuiltInZoomControls(true);
    map.setMultiTouchControls(true);

    GeoPoint startPoint = new GeoPoint(46.5328, 6.6306);
    IMapController mapController = map.getController();
    mapController.setZoom(11);
    mapController.setCenter(startPoint);

     if(myLocationOverlay == null)
        myLocationOverlay = new DirectedLocationOverlay(mContext);
    else
        map.getOverlays().remove(myLocationOverlay);

    map.getOverlays().add(myLocationOverlay);

    //Add Scale Bar
    ScaleBarOverlay myScaleBarOverlay = new ScaleBarOverlay(mContext);
    map.getOverlays().add(myScaleBarOverlay);

}

片段地图的布局

   <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/mapfragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <RelativeLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" >

        <org.osmdroid.views.MapView android:id="@+id/map"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent" />

    </RelativeLayout>
</LinearLayout>

当我第一次从片段4切换时，我有这个logcat
