The app is spending a lot of time in startup inflating XML. I suspect a
lot of it is due to the refreshActionBar() calls.
On a normal startup with NO refresh, the action bar was rebuilt 6 times.
If a refresh happens, the refresh callbacks get called in rapid
succession (20+ successive calls is not uncommon), which seemed really
wasteful.
