    canvas.drawBitmap(bkg, 0, 0, null);/*from ww w  .ja  v  a  2  s.co  m*/

    RenderScript rs = RenderScript.create(context);

    Allocation overlayAlloc = Allocation.createFromBitmap(rs, overlay);
    ScriptIntrinsicBlur blur = ScriptIntrinsicBlur.create(rs, overlayAlloc.getElement());
    blur.setInput(overlayAlloc);
    blur.setRadius(radius);
    blur.forEach(overlayAlloc);
