I've just encountered the same issue. POSTing a file succeeds with a 200 response, but _FILES is empty. I fixed the issue by specifying the Content-Length header. E.g.:

conn.setRequestProperty("Content-Length", Integer.toString(fileInputStream.available()));

Edit: So, when using this, the file appeared in _FILES but with an error code of 3. However, I also had a call to conn.setChunkedStreamingMode(1024);. Removing the Content-Length and the call to setChunkedStreamingMode worked for me, but I'm pretty sure that the empty _FILES is to do with the Content-Length field not being set correctly.
