Go

Go language or golang if you prefer

Writing services for Android in Go https://dennisforbes.ca/index.php/2014/03/19/go-golang-and-android/ I think the idea here is that you can replace C native code with GO. See also https://www.reddit.com/r/golang/comments/2kv0s1/go_14_on_android/

So it would be useful currently for example to talk to hardware.

Or maybe it could implement a tile downloader, that is, the network/concurrent part.

Settings

That ellipsis thing (three vertical dots) is called "Settings".

I want my app to show a menu when the user clicks on it, so I have to add a PreferencesActivity. I also need to associate the resources with it to define what shows up.
