Quest development documentation and sample projects deprecated?

Hello,

I passed few hours trying to make the following work:
https://developer.oculus.com/documentation/native/android/mobile-studio-basics/

I have my IDE configured, my quest 3 correctly detected.

I downloaded the mobile SDK https://developer.oculus.com/downloads/package/oculus-mobile-sdk/. (why not github?)

But the project is so out-of-date, I lost few hours trying to make it work.

Has someone working app samples in native mode, which I'd like to try first?

thanks and regards

Ludovic
