I am currently Using SPMC . One of the features that I use allows me to see my android apps within Kodi so I can add them as favorites.
This allows me to set up a mixture of Android apps and Kodi addons on the apptv home screen.
I am not able to navigate to this menu from APPTV . To add an Android app I have to switch skins. Add the App to Favorites. then switch back skins to add that Icon to favorites.
It would be awesome if the Android features and integration could be added to the skin but if not. I thought I would share this work around.
