best tutorials for native development?

I started watching the unity tutorials and then decided to look into going native, and compared to the educational resources unity provides, oculus stuff feels very haphazard and not well maintained. Their setup guide is using android studio 2.x and 4.x is the latest version. and their sample app doesn't even work without doing some tweaks. It's apparently been broken for at least a few months and no one has bothered to fix the sample or mention the tweak. 

So I'm just wondering if there's a better place to go in terms of resources to help you get started developing any quest apps? I'm not entirely opposed to going with unity since then we'd have cross platform. But I'd like to at least give native development a try first. Also, are there better forums than these?

Thanks
