Android Studio 2.x and [L]ubuntu 16.04, how is it?

Question

Android

I'm going to get back to Android development after a break.
And here just new versions of the environment and OS. There are questions:
1) Android Studio in Ubuntu x64 no longer requires 32-bit libraries to work?
Which bit system is better to take, 32 or 64?
2) Actual OpenJDK now = 8. Will Android Studio work fine with it? And how in general with OpenJDK instead of the official toad, were there problems before?

Answer 1

Recently set. Everything is good. All issues have been successfully saved. Pulls 32 bit libs and requires installation like jre instead of working on openjdk.
