I'm new to jPCT-AE. I've imported the HelloWorld-AE project into Android Studio and it gives a warning that the protected method isFullscreenOpaque is never called. I've checked the definition of the superclass, android.app.Activity, and it doesn't declare the method. The method isn't called from anywhere in the sample code.
I used logging to check that the method wasn't being called when running the example on my HTC Desire Z and then removed the method. The sample application seems to run fine without the method so I'm curious whether it is old code that is no longer required or if it is only needed on certain hardware, if it is called by reflection by a particular framework, etc.
