Android comes with the Apache HttpClient which has a number of methods for handling async communication. I don't have a lot of experience with that codebase but I suspect you will find some developers that have used the HttpClient as an async manager.
Here is the architecture I have found works well. 1. Create a communication manager singleton to act as the source for all your messages. That way all of your activities can access the manager. When the app shuts down it will remove the singleton. 2. Within the singleton, I created a queue for messages and a threadpool of HttpClient workers. You should do a search on asynchronous message queues in java. There will be quite a few samples for this. 3. The singleton has a call to send the message. Although not necessary you can pass in a parser and a listener to process and respond to the message respectively. Here is an example of how the thread/messaging system can work. http://code.google.com/p/apps-for-android/source/browse/trunk/Photostream/src/com/google/android/photostream/Flickr.java I apologize for not being able to provide code but I don't have that code available for public distribution. Keep in mind Android is no different than other java based asynchronous messaging. You should be able to find quite a few samples of code based on that.
