android studio or adt?

Question

IDE

I decided to start writing under andoid. Google suggests android studio or adt. And it seems that android studio will be the main supported development environment in the future.
I installed Android studio and was extremely dissatisfied with the use of memory - gig under hello world is overkill for me, and in general responsiveness is bad. Idea I so understanding too most. NDK does not know how, because C++ Idea does not support, and when to learn is also unclear.
Should I keep eating cactus with android studio? And in general, why did google need to introduce a replacement for adt?
