I have list view of data, and each item opens up a view that has a map embedded in it. The purpose of this map is to show a single marker. The code works fine, but if I have a lot of list items (50+), cycling back and forth is causing the app to throw OutOfMemory exceptions.
Can someone help me understand what I am doing wrong here.. I am guessing that there is something wrong in my Map initialization logic that is causing this.. and I am trying to figure that out.
public class DetailView extends Fragment implements OnInfoWindowClickListener {
private MapView mMapView;
private GoogleMap googleMap;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
mMapView = (MapView) v.findViewById(R.id.mapBusinessLocation);
mMapView.onCreate(savedInstanceState);
mMapView.onResume();//needed to get the map to display immediately
MapsInitializer.initialize(this.getActivity() );
//MapController myMapController = mMapView.getController();
googleMap = mMapView.getMap();
googleMap.setMyLocationEnabled(true);
CameraUpdate center=
CameraUpdateFactory.newLatLng(new LatLng(-20.269927,57.672729));
CameraUpdate zoom=CameraUpdateFactory.zoomTo(15);
googleMap.moveCamera(center);
googleMap.animateCamera(zoom);
}
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
placeMarker("test");
}
private Marker placeMarker(String title) {
//Get the hue
String pinColor = "#f29217";
int c = Color.parseColor(pinColor);
float[] pixelHSV = new float[3];
Color.colorToHSV(c, pixelHSV);
return googleMap.addMarker(new MarkerOptions()
.position(new LatLng(-20.269927,57.672729 ))
.title(title)
.snippet("")
.icon(BitmapDescriptorFactory.defaultMarker(pixelHSV[0])));
}
@Override
public void onResume() {
super.onResume();
if(mMapView != null) {
mMapView.onResume();
}
}
@Override
public void onPause() {
super.onPause();
if(mMapView != null) {
mMapView.onPause();
}
}
@Override
public void onDestroy() {
super.onDestroy();
if(mMapView != null) {
mMapView.onDestroy();
}
}
@Override
public void onLowMemory() {
super.onLowMemory();
if(mMapView != null) {
mMapView.onLowMemory();
}
}
}
The stack trace when the app crashes is given below..
