片段上的 osmdroid 导致内存不足
osmdroid on fragment cause out of memory
我正在尝试使用 Android Studio 在 Android 上开发地图应用程序。
经过一些操作后，我遇到了内存不足的异常...
我有一个 activity 抽屉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;
}
}
地图片段是这样构造的：
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;
}
还有这个：
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);
}
片段图布局
<?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"

</RelativeLayout>
</LinearLayout>
当我第一次从片段 4 切换时，我有这个 logcat

我不明白为什么....
非常感谢您的帮助...
从 https://code.google.com/p/osmdroid/issues/detail?id=265
中找到部分 "solution"
添加：
map.getTileProvider().clearTileCache();解决问题...
我正在尝试使用 Android Studio 在 Android 上开发地图应用程序。 经过一些操作后，我遇到了内存不足的异常...
我有一个 activity 抽屉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;
}
}
地图片段是这样构造的：
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;
}
还有这个：
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);
}
片段图布局
<?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"

我不明白为什么.... 非常感谢您的帮助...
从 https://code.google.com/p/osmdroid/issues/detail?id=265
中找到部分 "solution"添加：
map.getTileProvider().clearTileCache();解决问题...
