my code is:

loop 20 times:


    mapView.addMarker(new MarkerOptions()
                                        .position(new LatLng(latitude, longitude))
                                        .icon(BitmapDescriptorFactory
                                                .fromBitmap((bitmap)))
                                        .snippet(text + "             ")
                                        .title(mine_name));

For every new loop,i am removing markers on map and adding new ones.

I also took enough care about bitmap as

bitmap.recycle and assign bitmap with null after use of bitmap/

Answer 1

I have same issue in Google map v2, In my case, my map is refresh at every 30 Seconds. After half an hour my app is crash, I solved this issue using mMap.clear(); where mMapis my object of GoogleMap.

You can put this code before calling of for loop.

hope this will help you.

There is some issue on this google api. We have to wait the next release.... The BitmapDescriptorFactory have memory leak.
