I'm trying to convert byte[] into image. The byte[] comes from JSON and it's in     this format:

I'm using the following code convert byte[] to bitmap image.

            String encodedString="255,216,255,224,0,16,74,70,73,70,0,1,1,0,0,1,0,1,0....";
            byte[] encodeByte = encodedString.getBytes();
            System.out.println("encodeByte : "+encodeByte);
            System.out.println("encodeByte.length : "+encodeByte.length);
            Bitmap photo=BitmapFactory.decodeByteArray(encodeByte, 0,                     encodeByte.length);
            System.out.println("Bitmap photo : "+photo);
            btnImg.setImageBitmap(photo);

    I'm getting the following error in Logcat:

10-31 00:20:57.210: I/System.out(1315): encodeByte : [B@b3d249d8
10-31 00:20:57.210: I/System.out(1315): encodeByte.length : 18320
