You may just call the onBackPressed  and if you want some activity to display after the back button you have mention the      Intent intent   new Intent ResetPinActivity this  MenuActivity class       startActivity intent       finish      that worked for me

Override the onBackPressed   method as per the example by codeMagic  and remove the call to super onBackPressed    if you do not want the default action  finishing the current activity  to be executed

Just use the following code with initializing a field   private int count   0       Override public void onBackPressed         count        if  count  gt  1               If count is greater than 1  you can either move to the next          activity or just quit             Intent intent   new Intent this  SecondActivity class           startActivity intent           finish            overridePendingTransition          R anim push left in  R anim push left out              Quitting            finishAffinity          else           Toast makeText this   Press back again to Leave    Toast LENGTH SHORT  show                resetting the counter in 2s         Handler handler   new Handler            handler postDelayed new Runnable                  Override             public void run                     count   0                           2000             super onBackPressed

At first you must consider that if your activity which I called A extends another activity   B  and in both of   them you want to use onbackpressed function then every code you have in B runs in A too  So if you want to separate these you should separate them  It means that A should not extend B   then you can have onbackpressed separately for each of them

Just call the onBackPressed   method in the activity you want to show the dialog and inside it show your dialog

Yes  Only override it in that one Activity with   Override public void onBackPressed             code here to show dialog      super onBackPressed        optional depending on your needs     don t put this code in any other Activity

Best and most generic way to control the music is to create a mother Activity in which you override startActivity Intent intent  - in it you put shouldPlay true  and onBackPressed   - in it you put shouldPlay   true  onStop - in it you put a conditional mediaPlayer stop with shouldPlay as condition  Then  just extend the mother activity to all other activities  and no code duplicating is needed
