I also get the pop up that say's Unfortunately, app has stopped. I'm not sure where to go from here, since I'm fairly new. Let me know if I need to post any code.

Caused by: java.lang.ArrayIndexOutOfBoundsException: length=5

Your array does not have 6 elements

    navDrawerItems.add(new NavDrawerItem(navMenuTitles[5], navMenuIcons.getResourceId(5, -1), true, "50+"));

Array indexes start with 0 in pretty much every programming language case you where unaware.
