How to quit app using back button.

Now I am developing a simple app, but I am having trouble in making my app terminate.
On my android phone Galaxy A5, when pushing back button, my app doesn’t quit. It stays as it is.
In order to quit the app, I have to open my background app lists and push X button there.
I want to know how I can make my app turn off upon pushing back button.
I found the keyword , but I don’t know how i can make it from here.

If you want to give it a try, i’m sure you can get a lot of assistance from the community on slack:

I’ve made a an internal issue for this, but can’t guarantee when it will get fixed yet.
