Downgrading to Android Studio 1.4RC3 solved the issue. The problem is in AS, apparently, but still, an application should not be able to hang up the whole computer.
I did notice that when AS hangs, I can continue to use firefox and other apps, until I hit an icon in the Unity bar. Then the system hangs as a whole. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1515711 Title: lightdm hangs, windows freeze, lightdm restart helps most of the times.
