Why does my Action Bar have a shadow on Android Lollipop? I’ve set android:windowContentOverlay to null.
On Lollipop, the action bar shadow is provided using the new elevation API. 
To remove it, either call getSupportActionBar().setElevation(0), 
or set the elevation attribute in your Action Bar style.
