Thank you! I have successfully implemented a background service communicating with more activities using BroadcasReceiver. In this service I start a new thread for soket communication. Now my question is: what is the best way to communicate between the newly created thread and the service (I want to send back to the service the message received from tcp server)? I have implemented the new thread class as an inner class, so I can access members and methods from service class. It is working, but it is the right way to do this?
