ActionBar refresh when back button pressed

Question

I have a button on an action bar that reflects how many items are in the user's favourites. How can I get this to refresh when the back button is pressed?

replace invalidateOptionsMenu(); with supportInvalidateOptionsMenu(); if you are using actionbarsherlock – user3225075 Aug 27 '15 at 03:50

Use this:

@Override
public void onBackPressed() {
    //Refresh action bar        
}

That only fires on the current activity? How can I make the activity the user is navigating back to refresh the action bar? – user2610744 Feb 05 '14 at 12:15
Set some common variable (global) between the two activities. In this onBackPressed() just set that value. Later when you go back to the other activity, check for this value and then refresh action bar. – SoulRayder Feb 05 '14 at 12:17
