Huawei Map Kit - onMapReady() not called after getMapAsync()

Question

I'm trying to create a huawei variant of a locator feature of a project that uses google maps. But my problem is that onMapReady() callback does not trigger at all after getMapAsync()

This is how i call getMapAsync:

     val mapFragment = childFragmentManager.findFragmentById(R.id.fragment_huawei_map_container) as SupportMapFragment
     mapFragment.getMapAsync(this@SampleMapsFragment)

This works fine when using google maps depedencies as onMapReady() is getting called.

But when using huawei map dependencies, onMapReady callback does not trigger at all after getMapAsync()

Do you enable MapKit in console? Do you check SHA-256 in console? — mohax
I double checked right now to be sure and yes I already put SHA-256 and enabled mapkit in the console. — ccd
Do you test on Huawei device? Maps only work on Huawei devices — mohax
I have a non huawei device but a workaround I did is to install hms core apk — ccd
Yes, as I can see in docs, latest version of MapKit doesn't require Huawei device, if you have latest HmsCore app and OS>=7 — mohax

The onMapReady method needs to be reloaded. The following describes how to create a map instance using SupportMapFragment. For more details, see docs.

Add a Fragment object in the layout file (for example, activity_main.xml), and set map attributes in the file

<fragment xmlns:android="http://schemas.android.com/apk/res/android"        
    xmlns:map="http://schemas.android.com/apk/res-auto"
    android:id="@+id/mapfragment_mapfragmentdemo"
    class="com.huawei.hms.maps.SupportMapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    map:cameraTargetLat="48.893478"
    map:cameraTargetLng="2.334595"
    map:cameraZoom="10" />

To use a map in your app, implement the OnMapReadyCallback API in the MainActivity.java file. The sample code is as follows:

public class SupportMapDemoActivity extends AppCompatActivity implements OnMapReadyCallback {
    ...
}

In the MainActivity.java file, load SupportMapFragment in the onCreate() method and call getMapAsync() to register the callback. The sample code is as follows:

private SupportMapFragment mSupportMapFragment; 
mSupportMapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.mapfragment_mapfragmentdemo);
mSupportMapFragment.getMapAsync(this);

Call the onMapReady callback to obtain the HuaweiMap object. The sample code is as follows:

public void onMapReady(HuaweiMap huaweiMap) {
    Log.d(TAG, "onMapReady: ");     
    hMap = huaweiMap;
}

Run your project and then install your app to view the map in your app.
