How to speed up getting and clipping Bitmap from drawable?

Question

Problem - Tangible delay in getting and clipping a Bitmap from a drawable .

 Bitmap bt = BitmapFactory.decodeResource(context.getResources(), R.drawable.bg); bt = Bitmap.createScaledBitmap(bt, width, height, true);

How can I optimize / speed up getting a clipped Bitmap ?

@VAandrJ Thanks for the advice, but this method does not suit me.
If it does not suit you, then your application is built incorrectly, and you need not to look for another way (read a crutch ), but to remake the application in such a way that this method is suitable.

Try rewriting this:

 Bitmap oldBitmap = BitmapFactory.decodeResource(context.getResources(), R.drawable.bg); scaledBitmap = Bitmap.createScaledBitmap(oldBitmap, width, height, true); oldBitmap.recycle();

Rewrote did not help. BitmapFactory.decodeResource - 4 times longer than Bitmap.createScaledBitmap.
