Marble Maps App for Android as APK download or F-Droid package

[gregor.mi.sw]

Hello Marble devs,

I just read this blog post 
http://bernkastelsgsoc.blogspot.de/2017/06/moving-forward-dialing-phones-and.html, 
went to https://marble.kde.org/ and wondered why I cannot download the 
cool Kirigami app without Google Play. After some clicks I found this 
page https://marble.kde.org/install.php where there is an apk-Download 
for the Marble Maps but not for Behaim Globe.

I wound find it interesting if you could write some words why Marble 
Maps and Behaim Globe is not (yet?) available on F-Droid and what would 
be the next steps to accomplish this.

Thanks for all your efforts and best regards

Gregor
