Calling recycle() accelerates how quickly your bitmap memory can be returned to the heap. If it is convenient for you to call recycle(), it can certainly help avoid OutOfMemoryErrors. However, with the Bitmap object is garbage-collected, the finalizer will recycle() it for you, so unless you are running into memory problems, calling recycle() is not essential.
