Hi guys and gals,
I’ve tried following this tutorial (How to do Oculus Quest HAND TRACKING In Unreal Engine 4 - 4.24 - YouTube) to build a hand tracking app for the Oculus quest using this plugin: GitHub - rfsheffer/QuestHands: An Unreal Engine 4 plugin for the new Oculus Quest hands tracking. To tie us over till Oculus's official release..
I’ve downloaded the Oculus branch of UE 4.24 from github and ran it using Visual Studio. I’ve reinstalled the Codeworks for Android 1R7u1 from the Github-Branch I’ve downloaded and created a VR-Project just like in the tutorial.
Unfortunately I am unable to build the app. I always get the error “UATHelper: Packaging (Android (ASTC)): Z:\app\src\main\java\com\epicgames\ue4\WebViewControl.java:996: error: cannot find symbol”
Here is everything in the output log that comes after this error:

I can build and package apps for the oculus quest using the Epic Games Launcher UE4 version. I’ve successfully tested that. But here I don’t know what to do.
In the project settings - Android SDK I’ve set all the paths and set the SDK API Level to “matchndk” and the NDK API Level to “latest” (I’ve also tried android-19).
Has anyone had this problem?
Thanks in advance!
