yes, I followed the embeddedServer example to launch a server. It works well, from my PC (if I know the IP address) I can access the server and receive simple responses.
Debugging through the app I can see that I can also add longer path so supporting restful API is not a problem.
However returning an HTML page, that page that the user needs to see when browsing to the device does not work. I tried following the examples of returning static content but cannot get it to work. From what I can see it's an issue with the path to the assets folder that might not work for android.
