Crash on Unity Scene load of Sample Framework Oculus v1.39

[jackblock]

Hi, i'm able to build a testing unity project for my quest, and to see the first scene with HMD and controller tracking fine. However, using the SampleFramework's StartScene menu to load the DebugUI scene, it crashes my app back to the quest dashboard while loading. I made other builds of this project where i selected the DebugUI scene to be first to load, and there's no crash. It seems to be something about transitioning between the menu and the demos, not that the demos inherently crash the process..

I made two of my own simple testing scenes, with a timed scene load to swap between them, and there's no crash.

I'm using Unity 2019.1.7, and the latest Oculus package from the asset store (as of july 28th 2019). I followed the setup directions very closely, and never had trouble actually making the build or running the builds up until the demo scene loads.

Here's my adb logcat output approaching the crash. I see some warnings about the avatar loading etc, but those seem unconnected to the crash as the app ran fine until i triggered the debugui scene load:

I had a similar issue with my own app, but only after updating to the latest Oculus package version. I would recommend to downgrade to 1.38, then delete and regenerate the AndroidManifest.xml (through the Oculus menu in unity) and then add the following line to the AndroidManifest inside the <manifest> tag: 

<uses-feature android:name="android.hardware.vr.headtracking" android:version="1" android:required="true" />

You can find it under Assets/Plugins/Android.

Hope this works out for you!

I just saw this as well, seems to propose the same fix: https://forums.oculusvr.com/developer/discussion/79056/how-to-build-for-oculus-quest-w-unity-after-t...

Good to know!

Although, I can't find anywhere to download the 1.38 version, it seems Unity Asset Store doesn't let you download old versions, and i can't see oculus giving downloads either? The page here https://developer.oculus.com/downloads/package/unity-integration/1.38.0/ just redirects to the asset store.

Looks like they're getting a lot of poor reviews in the asset store for 1.39 for other issues as well.

you can get 1.38 here: https://developer.oculus.com/downloads/package/unity-integration-archive/1.38.0/
yeah, 1.39 version is either very buggy on the quest or the changes haven't been well documented. i'm not updating the plugin anymore for this project, now that i managed to undo the damage it caused after a day-long struggle.

I am seeing the same behavior in 1.40. I used this same code in earlier versions and scene loading worked fine.
I was able to do a work around and do everything from a single scene just to get the project out the door, but it sure would be nice to have scene loading working.
