Using ActionBar Up Navigation Android - API23

I'm implementing an app that has a activity to load a map and another activity to list the places the user selected on the map.

As I'm working with API23 , the toolbar was successfully displayed on activity master.

I need to implement up navigation in% of% of maps , so that the user can return to the main if desired. The problem is that I can not use activity in this toolbar because it is inheriting a activity , which does not support FragmentActivity .

So I tried solving by manually creating a setSupportActionBar and finally, updating ActionBar . As shown below, nothing is displayed in ActionBar.

Main activity with ActionBar OK

}

@Override
public void onMapReady(GoogleMap googleMap) {
    mMap = googleMap;

    // Add a marker in Sydney and move the camera
    LatLng sydney = new LatLng(-34, 151);
    mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney"));
    mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));
}

@Override
public boolean onOptionsItemSelected(MenuItem item){

    switch (item.getItemId()){
        case android.R.id.home:
            this.finish();
            return true;
        default:
            return super.onOptionsItemSelected(item);
    }

}

}
