Onnavigationitemselected Never Called On Actionbar's Spinner

I'm trying to build a drop down menu in the Action Bar Compat, as per the dev example: http://developer.android.com/guide/topics/ui/actionbar.html#Dropdown I can't get onNavigation

Solution 1:

Doesn't look like you're calling ActionBar.setListNavigationCallbacks.

From step 4 in the example:

Set the callback for the drop-down list with setListNavigationCallbacks(). For example:

actionBar.setListNavigationCallbacks(mSpinnerAdapter, mNavigationCallback);
