Android home screen

User has created a Qt application and made the modifications to AndroidManifest.xml to make it as a home screen. Example attached.

After the application is installed to the Android emulator, press the home button and system prompts to make this application as home screen just once or always. What ever option you select the home screen launched it blank.

If the app is started via Qt creator the issue reproduces but if it is launched directly from home button it works correctly. Video example attached.

Is this an issue with Qt or Android?
