Question

The problem is

Answer 1

As Ronald Kunenborg correctly states the problem is the Litte Endian / Big Endian conversion.

The simplest way is to write a short helper like this:

public static void writeShortLE(DataOutputStream out, short value) {
  out.writeByte(value & 0xFF);
  out.writeByte((value >> 8) & 0xFF);
}

This is very helpful if you record audio to a wave file with Android and you're in need of the short array, too.
