I have an application running in Wince wrote in C#; successful ported to Android using maui.net, this application needs to be in background, others application will send message to this background application, for print labels and check bluetooth status (Does the printer have paper? Is it online? Is it connected?). Then, I'm investigating how to create an application that communicates with others applications. I saw this video on YouTube, and it helped me a lot to understand background process, IPC, Binder, AIDL. from YouTube:"This screencast comes from AnDevCon IV presentation by Aleksandar Gargenta on Dec 5th, 2012."
