getting Null Pointer Exception in View.getDrawingCache()

Question

I am trying to get View converted in bitmap. In emulator my program is working fine and running as expected but when I run the same code in Device it gives null pointer Exception at particular line :

Bitmap b = Bitmap.createBitmap(view.getDrawingCache());

where view is object of RelativeLayout having Layout of current Activity. Can someone guide how can I resolve this issue. Thanks.

Can you post the rest of your code so we can see what is going on? Thanks! — BlackHatSamurai

You need to call measure and layout on your view before using getDrawingCache(). Otherwise it will return null.

You can still get null even with measure and layout set. This problem remains unsolved.
