Answer 1

public static byte[] toByteArray (Bitmap raw) {

    byte[] byteArray = null;

    try {
        ByteArrayOutputStream stream = new ByteArrayOutputStream ();
        raw.compress (Bitmap.CompressFormat.JPEG, 100, stream);
        byteArray = stream.toByteArray ();
    }
    catch (Exception e) {
        e.printStackTrace ();
    }

    return byteArray;
}
