1. Install Qt Creator 3.1.0 RC
2. Configure Qt Versions and Kits because autodetection didn't work
3. Create Qt Quick (the same for Qt Widgets) typical "Hello World" application
4. Build and Run to AVD (arm, x86 doesn't matter)

AR

1. As soon as deploy starts .apk file is build.
2. Deploy in Qt Creator finished successfully, but no application started in AVD. There is following error in Application Console:

   Unable to start "org.qtproject.example._3QtAT".

ER

.apk which build using Qt Creator should start and work successfully on AVD or on real device.
