How to use Back Button Android with cocos creator 2.3

Comment je peux faire pour gérer le bouton de retour d’un mobile Android ?
S’il vous plaît j’attends vos réponses

creator v2.3 does not have an implementation for this. If you want to use it then you have to override the onBackPressed method in an activity and use the jsb
to handle this in js.

Oh thank you very much
I will implement it and get back to you

I don’t really understand the procedure, if you could give me an example really I would be delighted
