My SDK manager shows that all android.arch.lifecycle.xxxx are up to date (Version 1.1.1)

May be related... it seems that ActionBarActivity is long-ago deprecated and "they" recommend extending AppCompatActivity or directly Activity instead of ActionBarActivity, since both already implement an ActionBar and dependencies are simplified.
