Recipe 8.4 Using a BroadcastReceiver to Obtain Locations
Rather than use the LocationListener class to obtain location data, you can instead use a PendingIntent object together with a BroadcastReceiver class. Using this approach, you can continue to listen for location data even if your application is closed by the user.
Solution
In the first recipe in this chapter (“Obtaining Geographical Location Using GPS, Wi-Fi, or Cellular Networks”), you learned how to obtain your geographical location using an instance of the LocationListener class.

However, if the activity is destroyed, the LocationListener object would also be destroyed, and you would no longer be able to track your location.
