Answer 1

This code works like a charm. However it seems that there are new updates to this as Google made new releases. Key differences are the following:

1. OnMapReadyCallback must be implemented:

   public class InsertMapsActivity extends FragmentActivity implements LocationListener, OnMapReadyCallback

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

   }

2. This code will no longer work:

   // Getting reference to the SupportMapFragment of activity_main.xml
   SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
   
   // Getting GoogleMap object from the fragment
   googleMap = fm.getMap();
   

Instead use this, which calls the callback in #1.

    // Obtain the SupportMapFragment and get notified when the map is ready to be used.
    SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
            .findFragmentById(R.id.map);
    mapFragment.getMapAsync(this);

3. References to the googleMap object need be placed in the OnMapReady callback to ensure that the object is initially assigned else null pointer errors would occur:

   @Override 
   public void onMapReady(GoogleMap googleMap) {
           this.googleMap = googleMap;
           // Enabling MyLocation Layer of Google Map
           this.googleMap.setMyLocationEnabled(true);
   googleMap.setOnMapClickListener(new GoogleMap.OnMapClickListener()
   {
       @Override
       public void onMapClick(LatLng latLng)
       {
           googleMap.clear();
           googleMap.addMarker(new MarkerOptions().position(latLng).title("Custom location").icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_BLUE)));
           garageLocation = latLng;
       }
   });
   }
