Why bitmaps not destroy?

Question

Whenever we create bitmaps objects,

• why they are not release by System.gc();.
• what is the best way to remove bitmap object

Answer 1

The bitmaps are kind of tricky, if you want to clear the used memory. I use bitmap.recycle(), it empties the heap, but not quite so. This is asked before. You can see this for more info: Android - Bitmap and memory management? and this:Android Bitmap freeing memory - none of this works

Answer 2

bitmap.recycle()
