Add separators between groups of actions bar menu items

I am creating an android action bar menu for an application. I'm looking for a way to show logical groupings of menu items. So, I have a:

Whereas I would like:

I am creating a menu like this:

@Override
public boolean onCreateOptionsMenu(Menu menu){
    //Note, on 2.3.x - 3.0 this is called when user opens the menu for the first timed
    //on 3.0+ it is called when the activity starts

    MenuInflater inflater = getMenuInflater();
    //adds the (currently empty) menu, after login it will be filled with options
    inflater.inflate(R.menu.menu, menu);

    return super.onCreateOptionsMenu(menu);
}


@Override
public boolean onPrepareOptionsMenu(Menu menu){
    menu.add("example");
    menu.add("example");
    return true;
}

      

        
        
        
      

    

XML Menu:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:compat="http://schemas.android.com/apk/res-auto"

    >
</menu>

      

        
        
        
      

    

I was hoping that menu groups would help, but I understand that they are only for changing all properties of menu items. At the same time, the submenu actually creates a hidden menu that opens freely when clicked.

Is there a way to create this logical grouping of menu items I'm looking for?
