Hi here the method I use to convert an int to ByteArray. I assume that
it suit with your needs.

Attention int is 4 Bytes long, if you want to produce longer byteArrays
with leading zeros, ajust the length variable.

private byte[] makeByteArray(int value, int length) {
       byte[] b = new byte[length];

       for (int i = 0; i < length; i++) {
           int offset = (b.length - 1 - i) * 8;
           b[i] = (byte) ((value >>> offset) & 0xFF);
       }
       if(b.length > 4) {
           for(int i = 0; i < b.length - 4; i++) {
               b[i] = 0;
           }
       }
       return b;
   }

Probably not a good idea to use an ArrayList<Byte> -- very wasteful of time and
space.

(Unless you know that you aren't doing it often, or with many bytes-worth of
input.)
