Android Google Maps API v2 - how to change marker icon

Question

I am trying to change marker icon. I get the image from one server directory.

When I put break point every time the "bit" result is null. And when I run the app I get java.lang.NullPointerException.

File file = new File("J:\\!!! DOCUMENTS\\!Outsourcing\\AppStore\\Benzinostancii\\Petrol\\logo.png");  Bitmap bit = BitmapFactory.decodeFile(String.valueOf(file));  double Dlat = lat.get(index); double Dlon = lon.get(index); String info = Arrayinfo.get(index); String name = Arrayname.get(index);  LatLng coordinate = new LatLng(Dlat, Dlon); map.addMarker(new MarkerOptions()     .icon(BitmapDescriptorFactory.fromBitmap(bit))     .position(coordinate)     .title(info) ).setSnippet(name); 

Answer 1

// latitude and longitude double latitude = 17.385044; double longitude = 78.486671;  // create marker MarkerOptions marker = new MarkerOptions().position(new LatLng(latitude, longitude)).title("Hello Maps");  // Changing marker icon marker.setIcon(BitmapDescriptorFactory.fromResource(R.drawable.my_marker_icon)));  // adding marker googleMap.addMarker(marker);
