I followed the instructions yesterday and now I found that AlienDalvik doesn't come up any more on my XA2. It says "cannot start" in the Android App Support settings page. I can hit "Start", then it will say "started", but when I try to open an Android application it says again on the top of the screen that it's starting the app support. EDIT: Not sure how exactly, but after uninstalling both, AlienDalvik and "Containers" and rebooting, the app support was back - even though I hadn't installed it again at that point. Files like /opt/alien were still around though.
