[android-developers] MulticastLock Example?
Can anyone point me to a good example of how one would use a MulticastLock to receive multicast packets? Do I just have to acquire the lock and then I can receive all the packets I want or should I only use the lock right when I'm receiving multicast packets?

[android-developers] Service restarting for no reason?
While debugging one of my apps (one that sits in the background and
logs accelerometer data), I noticed that it would randomly and without
any prompt reset itself. It would be running it's normal timer task
and suddenly it would stop, the create function would be called and
any running task would halt. Here's the trace:

[android-developers] Restart LogCat without restarting eclipse?
I was wondering if anyone knew how to restart LogCat without rebooting eclipse? Every once in a while LogCat will just die while I'm working and it seems like there should be a to get it working again. I've tried restarting the adb task, but that was just a haphazard guess at a solution. Any help? Any sentiment towards this annoying issue? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Problems with local network broadcast.
I'm trying to write a simple game-room api and am having trouble
broadcasting to the local network's broadcast ip. I got the code for
getting the broadcast address and how to send stuff to it here:
http://code.google.com/p/boxeeremote/wiki/AndroidUDP
and used it like this:
int PORT = 5;
int DISCOVERY_PORT = 6;
public void broadcast(String message) throws Exception {
InetAddress ina = mContext.getBroadcastAddress(); // this is
working
Log.v("ADDRESS", ina.getCanonicalHostName());
DatagramSocket socket = new DatagramSocket(PORT); // here's
where
the error occurs
socket.setBroadcast(true);
socket.setReuseAddress(true);
DatagramPacket packet = new DatagramPacket(message.getBytes(),
message
.length(), ina, DISCOVERY_PORT);
socket.send(packet);
}
I get an error "java.net.BindException: The address is already in
use". I thought at first this was because my local network was
blocking ports, but once I got onto my home network which blocks
nothing it still had the same issue. Is there something extra I have
to include to get it to send a packets to the broadcast ip? Thanks in
advance for any replies.

[android-developers] Point to point RPC for ad-hoc/local network communication between two or more clients?
I've seen android-xmlrpc, but it looks to be a server-centralized rpc api. Is there a project or RPC protocol built into android that allows me to do RPC between 2 or more android phones without a central server? I'm trying to avoid implementing a generic message passing system as I think RPC would make my code easier to work with. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Re: Avoiding garbage collection for smooth 2d animations
There are a lot of things that could trigger a slow down that wouldn't necessarily involve garbage collection. My guess is that your drawing function was kicked out of the cache when a background process tried to access the network or somethign like that. If you want really fast drawing you'll want to go with hard-core openGL 2d graphics commands and not the software rendered systems in the Canvas class. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

I wrote two apps and submitted them to the marketplace last night (been roughly 12 hours now). One was a LITE version of my app and the next was a Standard version. Neither shows up in a search on the Marketplace even though the LITE version of my app has been installed 25 times already.
