Answer 1

Drawable frame = loadingAnimation.getFrame(i); 

 if ((null != frame && ((BitmapDrawable)frame).getBitmap().isRecycled())) { 

 ((BitmapDrawable)frame).getBitmap().recycle(); 
 } else { 

 log("bitmap is already recycled"); 
 } 

 frame = null; 

Something like this atleast, maybe you need to change it to fit your code perfectly.
