Here's an idea. Convert the drawable image to a byte array... the array length is the size of the drawable image in bytes. Not sure if there is a better way...

That's the only way I know of. If you need it in KB, just divide the array.length by 1024. :)

I think u have to make it a file. But not sure whether it works

File root = new File(Environment.getExternalStorageDirectory() + File.separator + "temp" + File.separator); root.mkdirs(); File file= new File(root, "temp.png"); FileOutputStream fOut = new FileOutputStream(file); bmp.compress(Bitmap.CompressFormat.PNG, 100, fOut);//bmp is bitmap of ur image fOut.flush(); fOut.close();

Using file.length() should give you the file size.

yea. i asked him to save it to sd card and check for the file size

I don't know if this will work in all situations but you can use this:

Drawable d; long kbsize = ((BitmapDrawable)d).getBitmap().getByteCount() / 1024;
