In AppCompat based preferences, this#getContext returns an
object of android.view.ContextThemeWrapper class from where
we can safely extract a reference to our parent activity.

This is an activity, so it does not join the fragment backstack, but
instead piles on top
SettingsActivity
| -> MainActivity
| -> EditorFragment
| -> DetailFragment
| -> ListFragment
Without overriding the back button in the toolbar, it simply
kills the entire state on MainActivity and causes it to reload.
By calling finish() on the activity when home is pressed from the
item menu we can silently make it die without affecting any underlying
states held by MainActivity and instead return to the exact fragment
we launched settings from.

AppCompat is the preferred way to go for any app targetting
a wider range of SDKs.
Replace all activities and fragments with their AppCompat
variants and fixup method calls to use support variants.
