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

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()

Since you are using the Huawei's map kit to do these please check the following: You have generated a sha256 key and integrated HMS core, you can use this link to find out how.

If you have done all the above, make sure that agconnect-services.json is in the right place. Then, check if in your manifest you have:

A final thing to check is that if you have done enter image description here

I hope one of these will help as I was able to get onMapReady to trigger:

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

  1. 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" />
  1. 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 {
    ...
}
  1. 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);
  1. 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;
}
  1. Run your project and then install your app to view the map in your app.
