getMapAsync() in Fragment

Question

I having trouble implementing Google Map in Fragment.

This is my the part of my fragment class:

public class FragmentStoreFinderMap extends Fragment

Your code is returning this error because getMapAsync() does not return anything. If you look at the documentation for this function:

public void getMapAsync (OnMapReadyCallback callback)

Sets a callback object which will be triggered when the GoogleMap instance is ready to be used.

Note that:

This method must be called from the main thread. The callback will be executed in the main thread. In the case where Google Play services is not installed on the user's device, the callback will not be triggered until the user installs it. In the rare case where the GoogleMap is destroyed immediately after creation, the callback is not triggered. The GoogleMap object provided by the callback is non-null.

OnMapReadyCallback is an interface that needs implemented and passed to through this function. Nothing is currently assigned to your googleMap variable you should instead set its value in this block of code which implements OnMapReadyCallback

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


    }

This code should be in your Fragment somewhere. Since your Fragment already implements this interface you do pass it in as this.
