Qt Quick 2 - Can't render in Visual Studio Android Emulator

Dragone · wrote on 12 Jan 2016, 14:19

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 :
