Change ActionBar Home/Up Arrow Icon

Question

I noticed that with the new Google apps, they are updating the little Home/Up icon to not be the arrow, but three little lines (at least on Android 4.2).

Answer 1

It's called an ActionBarDrawerToggle and is intended to be used with the DrawerLayout.

You can find a sample implementation here and if you are only interested in the icons: you can download them from here.
