question: @ Override protected Bitmap alloc ( int size ) { return Bitmap . createBitmap ( 1 , ( int ) Math . ceil ( size / ( double ) BitmapUtil . RGB_565_BYTES_PER_PIXEL ) , Bitmap . Config . RGB_565 ) ; }
target:  Allocate a bitmap that has a backing memory allocacation of 'size' bytes. This is configuration agnostic so the size is the actual size in bytes of the bitmap.
