      Hi folks,
      I am starting using Qt Framework and I can't run my Qt Quick 2 app with Android Emulator in Visual Studio.

      Please help me find a solution.
      Should I file a bug ? Is there any bug tracker for Qt Framework ?

      If I posted in the wrong section please move this topic to the proper one.

      These are the error messages :
