Google maps in android snippet

I am having problems loading google maps in my snippet. It all starts with the recycler view adapter, which launches the "ViatgeDetallViewActivity":

Context context = mActivity.getApplicationContext(); 
                    Intent intent = new Intent(context, ViatgeDetallViewActivity.class);
                   holder.mViatge.getId());
                    intent.putExtra("desc",p.getDesc());
                    intent.putExtra("location",p.getLocation());
                    mActivity.startActivityForResult(intent,ACTIVITY_View);

      

        
        
        
      

    

This is my DetallViewActivity:

public class ViatgeDetallViewActivity extends AppCompatActivity {

ViatgeDetallViewFragment fragment;

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_view);
    Bundle extras = getIntent().getExtras();
    if(extras != null)
    {

        String s =  getIntent().getStringExtra("desc");
        Location l = getIntent().getParcelableExtra("location");

        Log.d("myTag", "estoy en el oncreate de detallviewActivity pasando pro extras" + s );


    }

        fragment = new ViatgeDetallViewFragment();


        getSupportFragmentManager().beginTransaction()
                .add(R.id.activity_fragment_view, fragment)  
                .commit();
     getFragmentManager().beginTransaction().add(R.id.activity_fragment_view, fragment).commit();
    }
}

      

        
        
        
      

    

With my ViatgeDetallViewFragment:

public class ViatgeDetallViewFragment extends Fragment implements OnMapReadyCallback {

private GoogleMap mMap;
private Marker mMarcadorActual;

public ViatgeDetallViewFragment() {
}
....
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.fragment_view, container, false);


    SupportMapFragment mapFragment =
            (SupportMapFragment)
                    getChildFragmentManager().findFragmentById(R.id.fragment_view_map);
    mapFragment.getMapAsync(this);


    return rootView;
}

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


   //ask for permissions..
        mMap.setMyLocationEnabled(true);


    LatLng sydney = new LatLng(-34, 151);
    mMarcadorActual = mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney"));

}

      

        
        
        
      

    

With layouts available, Activity_view:

<Linear ...

  <android.support.v7.widget.Toolbar
        android:id="@+id/tlbMenuView"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        android:elevation="4dp"
        />

    <FrameLayout
        android:id="@+id/activity_fragment_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        />

      

        
        
        
      

    

fragment_view:

<LinearLayout android:id="@+id/layout_fragment_view" xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent"
    >
..
    <fragment
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/fragment_view_map"
        class="com.google.android.gms.maps.MapFragment"></fragment>

</LinearLayout>

      

        
        
        
      

    

The problem comes when I try to start tje "ViatgeDetallActivity", I get this in the log:
