Some suggestions

[zielony12]

First of all I suggest to make the "clone from git" feature clone any git repository, not only these hosted on github.
My second suggestion is to add external build systems such as apache ant, gradle, maven or just an option to run an external command.
I also suggest adding Java AWT library. Pojav launcher has java awt bridge to run graphical windows inside of an android app.
Sincerely
