I've been reading/youtubing a lot about how I should start my next app and found out that the activities suggested as start activities in Android Studio may contain deprecated elements such as the ActionBar, and that I should rather start from scratch without an activity, and use the newly lollipop-introduced "Toolbar".
My question is: As I need a top bar of a kind (ActionBar/Toolbar) and a navigation drawer in my app, should I invest the time it needs to build the Toolbar opposed to starting with a NavigationDrawer activity from the beggining?
Will using an NavigationDrawer activity (with an ActionBar) mean that I'm staring a new app with old-fashioned kind of top bar?
