One of the unique features of mobile applications is location awareness. Mobile users take their devices with them everywhere, and adding location awareness to your app offers users a more contextual experience. The location APIs available in Google Play services facilitate adding location awareness to your app with automated location tracking, geofencing, and activity recognition.

The Google Play services location APIs are preferred over the Android framework location APIs (android.location) as a way of adding location awareness to your app. If you are currently using the Android framework location APIs, you are strongly encouraged to switch to the Google Play services location APIs as soon as possible.

This class shows you how to use the Google Play services location APIs in your app to get the current location, get periodic location updates, look up addresses, create and monitor geofences, and detect user activities. The class includes sample apps and code snippets that you can use as a starting point for adding location awareness to your app.

Note: Since this class is based on the Google Play services client library, make sure you install the latest version before using the sample apps or code snippets. To learn how to set up the client library with the latest version, see Setup in the Google Play services guide.

Lessons

Getting the Last Known Location
Learn how to retrieve the last known location of an Android device, which is usually equivalent to the user's current location.
Receiving Location Updates
Learn how to request and receive periodic location updates.
Displaying a Location Address
Learn how to convert a location's latitude and longitude into an address (reverse geocoding).
Creating and Monitoring Geofences
Learn how to define one or more geographic areas as locations of interest, called geofences, and detect when the user is close to or inside a geofence.
Recognizing the User's Current Activity
Learn how to recognize the user's current activity, such as walking, bicycling, or driving a car, and how to use this information to modify your app's location strategy.
Testing Using Mock Locations
Learn how to test a location-aware app by injecting mock locations into Location Services. In mock mode, Location Services sends out mock locations that you inject instead of sensor-based locations.
