Customize back navigation

Issue

First of all I read this article but is kind of complicated for me . All I need is to go to an activity I want (navigate if exist in back stack or start it with Intent if it's not ) in onBackPressed() override . should I manage back stack or something else ? if yes how ? and if no what is a simple way for that ?

P.S : I dont use ActionBar

Solution

SOLVED: as mentioned in this answer and according to comments , if we want to just bring an (existing )Activity to front , setting Intent flag to :

    Intent.FLAG_ACTIVITY_REORDER_TO_FRONT

wont create new instance of Activity we want and just bring it front . this would be useful if we have multiple activities on top of the one .
