How to determine which bitmap resource was downloaded (ldpi, mdpi or hdpi)?

Question

I created several raster images - one for each folder (mdpi, hdpi, ldpi). Can someone show me some code or tell me the appropriate method that will allow me to determine which Android resource I decided to download.

Thank,

DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);

switch(metrics.densityDpi)

}

Bitmap :

Access to resources can be obtained in the form of raw data: use AssetManager.open (..) Then you can use BitmapFactory.decodeStream (..) to create a bitmap image from the data stream.
