Using TFTP in Android, Works fine out of android, Hangs on sendFile in android

It all compiles fine and works like a charm, H开发者_如何转开发owever when i set it up in Android it still compiles fine but when gets to tftp.sendFile it just sits there. I've checked the packets with Wireshark and nothing is being sent.

What could be the issue here? Spent a few hours debugging and nailed it down to that tftp.sendFile

If i let it run for the 60 seconds it just times out with the following

WARN/System.err(2227): Error: I/O exception occurred while sending file. WARN/System.err(2227): Connection timed out.

So its loading the methods fine

EDIT: And i've got "android.permission.INTERNET" in my manifest file.

Well, I worked it out, emulator seems to block it, but it works fine on the device.
