![]() ![]() LocationManager.getProvider(LocationManager.GPS_PROVIDER) Īlternatively, you can provide some input criteria such as accuracy, power requirement, monetary cost, and so on, and let Android decide a closest match location provider. The snippet below asks for a provider backed by the GPS. ![]() For example, a points of interest check-in application would require higher location accuracy than say, a retail store locator where a city level location fix would suffice. Generally, a location provider with a greater accuracy, like the GPS, requires a longer fix time than a less accurate one, such as a network-based location provider.ĭepending on your application's use case, you have to choose a specific location provider, or multiple providers, based on similar tradeoffs. Location providers may have different performance characteristics in terms of time-to-fix, accuracy, monetary cost, power consumption, and so on. While not required, most modern Android-powered devices can receive location updates through multiple underlying technologies, which are abstracted to an application as LocationProvider objects. (LocationManager) this.getSystemService(Context.LOCATION_SERVICE) If your application intends to receive location updates in the foreground (within an Activity), you should usually perform this step in the onCreate() method. Similar to other system services, a reference can be obtained from calling the getSystemService() method. LocationManager is the main class through which your application can access location services on Android. Note that declaring the ACCESS_FINE_LOCATION permission implies ACCESS_COARSE_LOCATION already.Īlso, if a network-based location provider is used in the application, you'll need to declare the internet permission as well. The more accurate GPS requires the ACCESS_FINE_LOCATION permission. For example, you need to declare the ACCESS_COARSE_LOCATION permission if your application uses a network-based location provider only. If permissions are missing, the application will get a SecurityException at runtime.ĭepending on the LocationManager methods used, either ACCESS_COARSE_LOCATION or ACCESS_FINE_LOCATION permission is needed. The first step of setting up location update access is to declare proper permissions in the manifest. Declare Proper Permissions in Android Manifest ![]() In this lesson, you'll learn what these steps entail. Before your application can begin receiving location updates, it needs to perform some simple steps to set up access. ![]()
