Search for Nearby Locations
To search for nearby locations, as shown in Figure 8-16 , use the current user's location, obtained with
getUserLocation , and then use the locationsWithinDistance . The locationsWithinDistance method in Location
service class uses a method called distance to return a string value of the distance between the starting point and the
respective location (Listing 8-41).
