        View view = inflater.inflate(R.layout.fragment_map, container, false);

        SupportMapFragment mapFragment = (SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.google_map);
        mapFragment.getMapAsync(new OnMapReadyCallback() {
            @Override
            public void onMapReady(GoogleMap googleMap) {
                // Handle map interactions here
                googleMap.setOnMapClickListener(new GoogleMap.OnMapClickListener() {
                    @Override
                    public void onMapClick(LatLng latLng) {
                        // Add a marker on the clicked location
                        googleMap.addMarker(new MarkerOptions().position(latLng).title("Marker"));
                        // Animate the camera to the clicked location
                        googleMap.animateCamera(CameraUpdateFactory.newLatLngZoom(latLng, 15f));
                    }
                });
            }
        });

        return view;
    }
}

Step 4: Integrate the Map Fragment into Your Activity

  1. In your activity_main.xml file, add a FrameLayout to serve as the container for your map fragment:

    <?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <FrameLayout
        android:id="@+id/frame_layout"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</androidx.constraintlayout.widget.ConstraintLayout>

  2. In your MainActivity.java file, add the following code to load the MapFragment into the FrameLayout:

    public class MainActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // Initialize the MapFragment and add it to the FrameLayout
        Fragment fragment = new MapFragment();
        getSupportFragmentManager()
                .beginTransaction()
                .replace(R.id.frame_layout, fragment)
                .commit();
