Wrong Information about android hardware back button about react-navigation.github.io

[vonovak]

Then this guide is probably wrong: https://reactnavigation.org/docs/custom-android-back-button-handling.html

cc @vonovak - perhaps we should change this to use willBlur / willFocus?

[brentvatne]

oh my bad, this is for the redux integration doc.

this is actually correct @dbrezack - you should only add it once on the root. react-navigation's root navigation container does the same thing (except in the constructor rather than componentWillMount)

you shouldn't add this to every screen. just the root screen as shown in the doc. perhaps it could be more clear about that? cc @Ashoat

[dbrezack]

What about an instance which you want to goBack in some screens and do something custom in others ?

@brentvatne You are right didn't see that it was in the AppNavigation component.
