Oculus Quest freezes on loading

Hi

I built a test app from ready scene of Oculus Sample Frameworks. But app got frozen in loading page of Oculus Quest.
My Unity version is 2018.1.2f1

 

Did you remove VULKAN rendering ?

 

I had encountered this before, and the cause was a NullRef exception that was being triggered each from, locking the execution of the app.

It's really touch to find these kind of things from running just on the device. You can use logcat to check the Android logs and see if that shows you anything.

 

Yes I did

 

logcat shows that app run and counts FPS but in quest display frozen loading dots.

Code (CSharp):

1. I VrApi   : APP NAME = VRTest
2. I VrApi   : APP VERSION = 0.1 versionCode 1 internalVersionName <none>
3. I VrApi   : APP VR TYPE = vr_only
4. I VrApi   : APP PACKAGE NAME = com.Company.VRTest
5. I VrApi   : APP ACTIVITY CLASS = com.unity3d.player.UnityPlayerActivity
6. I VrApi   : ovrModeParms::VRAPI_MODE_FLAG_ALLOW_POWER_SAVE = 1
7. I VrApi   : ovrModeParms::VRAPI_MODE_FLAG_RESET_WINDOW_FULLSCREEN = 1
8. I VrApi   : ovrModeParms::VRAPI_MODE_FLAG_NATIVE_WINDOW = 1

10. I VrApi   : ovrModeParms::VRAPI_MODE_FLAG_FRONT_BUFFER_565 = 0
11. I VrApi   : ovrModeParms::VRAPI_MODE_FLAG_FRONT_BUFFER_SRGB = 0

15. I VrApi   : OVR::Stats thread started
16. I VrApi   : System brightness = 255
17. D VrApi   : VrApi::isWifiConnected exception: Make sure android.permission.ACCESS_NETWORK_STATE is set in the manifest.
18. I VrApi   : Set brightness to 255
19. I VrApi   : Set DND mode to false
20. D VrApi   : targetSDKVersion 28
21. I VrApi   : System DND mode = false
22. .
23. .
24. .
25. I VrApi   : FPS=72,Prd=44ms,Tear=0,Early=65,Stale=0,VSnc=1,Lat=1,Fov=0,CPU4/GPU=2/2,1651/414MHz,OC=FF,TA=0/0/0,SP=N/N/N,Mem=1804MHz,Free=2027MB,PSM=0,PLS=0,Temp=34.0C/0.0C,TW=0.00ms,App=9.39ms,GD=2.44ms

when I play in Unity editor, a warning message shows on Unity console said
"Virtual Reality SDK Oculus failed to initialize.
Will attempt to enable None instead."
