I have one problem. I've built Android Oculus360videos example, prepared it for me. I see two parts of the screen and video is playing but doesn't have any reaction when I rotate my device.
I need to check accelerometer myself or it's done in the libs? Any ideas?
The SDK will handle head rotation on its own if you're using the sample apps.
Are you putting the phone into the Gear VR headset? The app won't do any tracking when the phone is not connected. When you insert the phone, do you head a "bloop" sound when you seat it into the connector? That indicates when a proper connection is made. Also, does the headtracking work in other applications?
