            View v1 = getWindow().getDecorView().getRootView();
            v1.setDrawingCacheEnabled(true);
            bitmap = Bitmap.createBitmap(v1.getDrawingCache());
            v1.setDrawingCacheEnabled(false);

To get screenshot of views not belonging to the app developed by you, use MediaProjectionManager .

But you have to first take the permission of the user to do so.

Note: This is applicable for Android 5.0(Lolipop) onwards.
