Android: Getting the Broadcast Address of your Wifi connection

Sunday, May 1st, 2011

If you ever need to know the broadcast address of your wifi connection…

private InetAddress getBroadcastAddress() throws IOException {
	WifiManager myWifiManager = (WifiManager) getSystemService(WIFI_SERVICE);
	DhcpInfo myDhcpInfo = myWifiManager.getDhcpInfo();
	if (myDhcpInfo == null) {
		System.out.println("Could not get broadcast address");
		return null;
	}
	int broadcast = (myDhcpInfo.ipAddress & myDhcpInfo.netmask)
				| ~myDhcpInfo.netmask;
	byte[] quads = new byte[4];
	for (int k = 0; k < 4; k++)
	quads[k] = (byte) ((broadcast >> k * 8) & 0xFF);
	return InetAddress.getByAddress(quads);
}

Testing UDP in the Android Emulator

Saturday, April 30th, 2011

Well it looks like my Android HTC Wildfire is fucked…. looks like receiving UDP broadcasts does not work according to this

So it’s off to the emulator to test there … ugggh.

1. First telnet localhost 5554 to get you to the emulator console
2. Then simply redir add udp:4343:4343 to forward that port on the local machine to the emulator.

This problem with HTC phones isn’t going to do the Android cause any good :(
