I am using certain bitmaps in my app which I am storing in the Drawable folder. When the user uses these bitmap in some kind, I want those bitmaps to be deleted. How shall I Implement this without using any kind of databases?

Edit:
I came to know that res/drawable is Read only. Then is there a technique to save the bitmaps anywhere else and then delete them. Can SQLite database be used for this purpose? If Yes, some code would be very helpful.
