Hi Robert,
          I tried to reproduce this issue on my machine but the sample project
given by you is not going to build and it has TWO build  error. These are mentioned in gist: https://gist.github.com/saurabh360/3f8f8b92c747918d351c

Could You please provide me the sample project again that has no build error? So that I can Reproduce this issue at my end.

I'm having exactly the same same issue. Any idea how to fix that? (and BTW, the bug this is marked as duplicate of seems unrelated).
Comment 6 Greg Munn 2014-08-21 12:10:12 UTC
Simone, different symptoms, same bug. Try changing the start up project to be the android project. Also, this should be fixed in 5.3 - could you please try it with that version and let me know.

It's in beta, you can switch to the beta channel when you check for updates. you can switch back afterwards if you want / need.
Comment 9 simone.busoli 2014-08-21 12:37:12 UTC
Ok, I confirm it's fixed in 5.3. It would be useful to track which version has the fix.
