I would like to point out few things that are in my opinion urgent right now for android-vcmi.
When the VCMI app is installed it doesn’t come with mod for different resolutions. I think even the additional ability sprites for units are missing but not so sure about that right now. They should be provided already in the apk or there should be at least some links to the files.
In-game session could be made a bit more pleasant. First of all the app doesn’t support fullscreen. If there should be a back arrow it could be implemented as a floating button somewhere in a corner.
And when the chosen resolution doesn’t fill entire screen then the artifacts could be covered by a single coloured layer or some kind of sprite so that it doesn’t look so bad.
