VR in Godot 4: Oculus Quest 2 in Android
Oculus Quest Androud apps in Godot 4 (and any environment) can be a mission to build as you need to run through a process installing a lot of software first before you can test to see if it works.
Use the Godot 4 Documentation to help you.
Start by setting up Exporting for Android. Build a basic Android app at this point at test that it builds and runs before moving onto XR apps.
Next configure Deploying to Android for XR (Virtual Reality).
Then focus on setting up the scene in Setting up XR.
