First, I would like to announce, I have been chosen as a Google Summer of Code student and my task is to provide a working version of Marble on Android at the end of the summer.
This is a very important for Marble, because Marble currently only available on Desktop and on same rare mobile platforms (Maemo, MeeGo) but on the most widespread platform (Android), not. It is very sad because it is more and more common in education systems that they use TVs, tablets and smartphones with Android so they cant use Marble as an educational tool.
The supported Android platforms will be Android v2.3.3 (API level 10) and higher, because it will be ported with Qt for Android.
The work has been started. Stay tuned...
