Does passing BufferedInputStream/BufferedOutputStream classes to the
Bitmap functions like compress and decodeStream make these functions
run any faster? Or does the underlying code for these function take
care of wrapping a buffer around?
Which one is better or faster of the belowmentioned or does it make no
difference?

Q1.
i. bitmap.compress(Bitmap.CompressFormat.PNG, 100, bos);// bos =
BufferedOutputStream
ii. bitmap.compress(Bitmap.CompressFormat.PNG, 100, os);//
FileOutputStream

Q2.
i. BitmapFactory.decodeStream(new BufferedInputStream(in));
ii. BitmapFactory.decodeStream(new FileInputStream(in));

Thanks.
