RecyclerView is missing

Question

I just installed the new SDK tools (Android L Developer Preview), and I\'m trying to use RecyclerView but it seems to be missing.

From my understanding

Answer 1

For me, I was able to fix it by updating to the most recent version of android studio (3.3). I ran into some issues after updating which I resolved by using the "Import Project option" instead of just re-opening the project.
