Not sure what to do - I've been trying to build and run some basic scenes that come with the Oculus Integration package and every time I get a black screen. Several home button presses will pull me out of the demo and then I can proceed back into the unknown sources application which just goes black again. No apparent issues during build...
If I hit the play button I'm able to preview the scene on the Rift fine.
I also tried using side-loader software from Headjack to install the .apk onto the GO, but again it launches a black screen.
