When I bought my VSX-1020-K I was amazed by the possibility to remote-control it via the network-interface (great job, Pioneer!). Unfortunately it was only possible via an App via iPhone. As I'm an avid lover of Android, I decided to program an App myself.
learning curve (Android is NOT Java) I managed to to a basic program
(the "normal" screen you see when you start up).
Fortunately the Receiver is able to do so much more, and I continued to add features and designs to the final version it is now.
