I just write my first tutorial on my recent Portfolio to explain how you can get information from an external android service app to a Unity application.
Have you tried to communicate back to the Service by passing some data? Was it successful? I am trying to do it but couldn’t succeed. Can you post that too step by step?
Interesting stuff! I’ve been doing a lot of work recently with writing custom Android plugins, but they’ve all been Fragments and I haven’t played with Services yet.
