Neither preferencesResource given, nor overriden getFragment

Error message

Neither preferencesResource given, nor overriden getFragment()

What it means

Configuration guard in AbstractDashboardActivity.getFragment: the subclass neither set preferencesResource nor overrode getFragment(), so there is no settings fragment to display. It fires from onCreate when both configuration avenues are missing.
