Empty Google-Maps Activity

Nötter :

I'm working on a Google Maps Activity. I went to the Google Developer Page and go step by step through the installation steps.

I added the key and the dependencies but it still show just a empty map with the google logo in the left corner

This is my MapActivity

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {

    private GoogleMap mMap;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_maps);
        // Obtain the SupportMapFragment and get notified when the map is ready to be used.
        SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
                .findFragmentById(R.id.map);
        mapFragment.getMapAsync(this);
    }

    @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));
    }
}

This is my activity_maps

             The API key for Google Maps-based APIs is defined as a string resource.
             (See the file "res/values/google_maps_api.xml").
             Note that the API key is linked to the encryption key used to sign the APK.
             You need a different API key for each encryption key, including the release key that is used to
             sign the APK for publishing.
             You can define the keys for the debug and release targets in src/debug/ and src/release/.

    TODO: Before you run your application, you need a Google Maps API key.

    To get one, follow this link, follow the directions and press "Create" at the end:

    https://console.developers.google.com/flows/enableapi?apiid=maps_android_backend&keyType=CLIENT_SIDE_ANDROID&r=CC:C3:BA:D9:2B:3D:3C:17:7D:C5:70:00:A6:25:39:C0:0A:E4:07:F1%3Bcom.example.myapplicationss

    You can also add your credentials to an existing key, using these values:

    Package name:
    CC:C3:BA:D9:2B:3D:3C:17:7D:C5:70:00:A6:25:39:C0:0A:E4:07:F1

    SHA-1 certificate fingerprint:
    CC:C3:BA:D9:2B:3D:3C:17:7D:C5:70:00:A6:25:39:C0:0A:E4:07:F1

    Alternatively, follow the directions here:
    https://developers.google.com/maps/documentation/android/start#get-key

    Once you have your key (it starts with "AIza"), replace the "google_maps_key"
    string in this file.

    <string name="google_maps_key" templateMergeStrategy="preserve" translatable="false">MY_KEY</string>
