Android API Google Maps V2 OutOfMemory Exception

Question

I have a list view of the data, and each element opens a view in which there is a map built into it. The purpose of this map is to show one marker. The code works fine, but if I have many list items (50+), looping back and forth causes the application to throw OutOfMemory exceptions.

Can someone help me understand what I'm doing wrong here. I suppose there is something wrong with my card initialization logic, and I'm trying to figure it 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();
                }
        }

}
