Google Maps does not display in fragment

I apologise if I'm posting a question that is similar to many others but each of them have different implementations of the google map and to try them all means to completely break my code and since I'm new to Android Development I'd rather not risk it if you can help me find out what is wrong with my map. Thanks.

When I run my app this is what I get: enter image description here

This is my Gradle.build (app):

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    buildToolsVersion "29.0.2"
    defaultConfig {
        applicationId "com.example.binfo"

        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

As per your code, there is no mistake I find out, but as per your screenshot, It looks like your internet connection is missed, So can you please with a proper internet connection and check it first.

In your fragment use MapView:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".HomeFragment">

    <com.google.android.gms.maps.MapView
        android:id="@+id/mapView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@+id/llSelectDetails" />

</RelativeLayout>

In your fragment use:

  public class HomeFragment extends Fragment implements OnMapReadyCallback {

    private GoogleMap mMap;
    private MapView mMapView;

    @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                                 Bundle savedInstanceState) {
            // Inflate the layout for this fragment
            View rootView = inflater.inflate(R.layout.fragment_home, container, false)

             /*
             * Configure Mapview and sync to google map.
             */
            mMapView = rootView.findViewById(R.id.mapView);
            mMapView.onCreate(savedInstanceState);
            mMapView.getMapAsync(this);
            mMapView.onResume(); // needed to get the map to display immediately

             //your code
            return rootView;
    }

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

It will work fine. Also, check your map key and internet connection.
