38 <p>If your app can continuously track location, it can deliver more relevant
40 way while walking or driving, or if your app tracks the location of assets, it
41 needs to get the location of the device at regular intervals. As well as the
42 geographical location (latitude and longitude), you may want to give the user
45 in the {@link android.location.Location} object that your app can retrieve

50 <p>While you can get a device's location with

54 a more direct approach is to request periodic updates from the fused location

58 determined by the providers, the location permissions you've requested, and

64 method in the fused location provider.
66 <h2 id="get-last-location">Get the Last Known Location</h2>
68 <p>The last known location of the device provides a handy base from which to
69 start, ensuring that the app has a known location before starting the
70 periodic location updates. The lesson on
71 <a href="retrieve-current.html">Getting the Last Known Location</a> shows you
72 how to get the last known location by calling
73 <a href="{@docRoot}reference/com/google/android/gms/location/FusedLocationProviderApi.html#getLastLocation(com.google.android.gms.common.api.GoogleApiClient)">{@code getLastLocation()}</a>.

76 {@link android.location.Location} object in the global variable
79 <p>Apps that use location services must request location permissions. In this
80 lesson you require fine location detection, so that your app can get as
81 precise a location as possible from the available location providers. Request

94 <h2 id="updates">Request Location Updates</h2>
96 <p>Before requesting location updates, your app must connect to location
97 services and make a location request. The lesson on
98 <a href="change-location-settings.html">Changing Location Settings</a>
99 shows you how to do this. Once a location request is in place you can start
101 <a href="{@docRoot}reference/com/google/android/gms/location/FusedLocationProviderApi.html#requestLocationUpdates(com.google.android.gms.common.api.GoogleApiClient, com.google.android.gms.location.LocationRequest, com.google.android.gms.location.LocationListener)">{@code requestLocationUpdates()}</a>.
107 <p>Depending on the form of the request, the fused location provider either
109 <a href="{@docRoot}reference/com/google/android/gms/location/LocationListener.html">{@code LocationListener.onLocationChanged()}</a>
110 callback method and passes it a {@link android.location.Location} object, or
113 that contains the location in its extended data. The accuracy and frequency of
114 the updates are affected by the location permissions you've requested and the
115 options you set in the location request object.</p>

154 <p>The fused location provider invokes the
155 <a href="{@docRoot}reference/com/google/android/gms/location/LocationListener.html#onLocationChanged(android.location.Location)">{@code LocationListener.onLocationChanged()}</a>
156 callback method. The incoming argument is a {@link android.location.Location}
157 object containing the location's latitude and longitude. The following snippet
159 <a href="{@docRoot}reference/com/google/android/gms/location/LocationListener.html">{@code LocationListener}</a>
