Maps Android Studio is not displayed when the app is downloaded from play store

I'm having a problem showing google maps in my app, before the map was shown correctly, the marker with the requested approach, when I emulate my project in the emulator or I do it on my cell phone through cable, the map will be shows correctly, but now that I uploaded my app to play store, the map is not shown on the devices that download it from there.

I have configured the credential in GoogleApi for several months, now I have generated a new key and added it to the project but it still does not show me the map.

When I applied for the first key in GooleAPIs my project had a different package name than the one I now have and I am not sure if this is the reason, I searched in GoogleAPIs the project settings to change the project name but I did not encounter, I would also like to know if creating a new project in GoogleAPIs this could be arranged.

Next I show you the java file, the xml and some screenshots of GoogleAPIs, I appreciate your help.

JAVA

public class Fragment_Rutas extends Fragment implements OnMapReadyCallback {

public Fragment_Rutas() {
    // Required empty public constructor
}

@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.fragment_rutas, container, false);

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

    return v;
    //AIzaSyBfIvrguKAhUaW8CA0dvgyEXEFADleNCtc
}

@Override//acercamiento
public void onMapReady(GoogleMap googleMap) {

    LatLng bogota = new LatLng(4.653421, -74.145150);
    googleMap.addMarker(new MarkerOptions().position(bogota)
            .title("Uniagustiniana"));
    googleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(bogota, 16.1f));
}
}

XML

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="300dp"
    android:background="#94dea7">

    <fragment
        android:id="@+id/map"
