LocationManager

public class LocationManager
extends Object

java.lang.Object
↳	android.location.LocationManager

This class provides access to the system location services. These services allow applications to obtain periodic updates of the device's geographical location, or to fire an application-specified Intent when the device enters the proximity of a given geographical location.

Unless noted, all Location API methods require the ACCESS_COARSE_LOCATION or ACCESS_FINE_LOCATION permissions. If your application only has the coarse permission then it will not have access to the GPS or passive location providers. Other providers will still return location results, but the update rate will be throttled and the exact location will be obfuscated to a coarse level of accuracy.

Instances of this class must be obtained using Context.getSystemService(Class) with the argument LocationManager.class orContext.getSystemService(String) with the argument Context.LOCATION_SERVICE.

MODE_CHANGED_ACTION

added in API level 19

String MODE_CHANGED_ACTION

Broadcast intent action when LOCATION_MODE changes. For use with the LOCATION_MODE API. If you're interacting with isProviderEnabled(String), usePROVIDERS_CHANGED_ACTION instead. In the future, there may be mode changes that do not result in PROVIDERS_CHANGED_ACTION broadcasts.

addProximityAlert

added in API level 1

void addProximityAlert (double latitude, 
                double longitude, 
                float radius, 
                long expiration, 
                PendingIntent intent)

Set a proximity alert for the location given by the position (latitude, longitude) and the given radius.

When the device detects that it has entered or exited the area surrounding the location, the given PendingIntent will be used to create an Intent to be fired.

The fired Intent will have a boolean extra added with key KEY_PROXIMITY_ENTERING. If the value is true, the device is entering the proximity region; if false, it is exiting.

Due to the approximate nature of position estimation, if the device passes through the given area briefly, it is possible that no Intent will be fired. Similarly, an Intent could be fired if the device passes very close to the given area but does not actually enter it.

After the number of milliseconds given by the expiration parameter, the location manager will delete this proximity alert and no longer monitor it. A value of -1 indicates that there should be no expiration time.

Internally, this method uses both NETWORK_PROVIDER and GPS_PROVIDER.

Before API version 17, this method could be used with ACCESS_FINE_LOCATION or ACCESS_COARSE_LOCATION. From API version 17 and onwards, this method requires ACCESS_FINE_LOCATION permission.

Requires the ACCESS_COARSE_LOCATION or ACCESS_FINE_LOCATION permissions.

Parameters
`latitude`	`double`: the latitude of the central point of the alert region
`longitude`	`double`: the longitude of the central point of the alert region
`radius`	`float`: the radius of the central point of the alert region, in meters
`expiration`	`long`: time for this proximity alert, in milliseconds, or -1 to indicate no expiration
`intent`	`PendingIntent`: a PendingIntent that will be used to generate an Intent to fire when entry to or exit from the alert region is detected

Throws
`SecurityException`	if `ACCESS_FINE_LOCATION` permission is not present

requestLocationUpdates

added in API level 9

void requestLocationUpdates (long minTime, 
                float minDistance, 
                Criteria criteria, 
                PendingIntent intent)

The requestLocationUpdates() and requestSingleUpdate() register the current activity to be updated periodically by the named provider, or by the provider matching the specified Criteria, with location and status updates.

It may take a while to receive the first location update. If an immediate location is required, applications may use the getLastKnownLocation(String)method.

Location updates are received either by LocationListener callbacks, or by broadcast intents to a supplied PendingIntent.

If the caller supplied a pending intent, then location updates are sent with a key of KEY_LOCATION_CHANGED and a Location value.

The location update interval can be controlled using the minTime parameter. The elapsed time between location updates will never be less than minTime, although it can be more depending on the Location Provider implementation and the update interval requested by other applications.

Choosing a sensible value for minTime is important to conserve battery life. Each location update requires power from GPS, WIFI, Cell and other radios. Select a minTime value as high as possible while still providing a reasonable user experience. If your application is not in the foreground and showing location to the user then your application should avoid using an active provider (such as NETWORK_PROVIDER or GPS_PROVIDER), but if you insist then select a minTime of 5 * 60 * 1000 (5 minutes) or greater. If your application is in the foreground and showing location to the user then it is appropriate to select a faster update interval.

The minDistance parameter can also be used to control the frequency of location updates. If it is greater than 0 then the location provider will only send your application an update when the location has changed by at least minDistance meters, AND at least minTime milliseconds have passed. However it is more difficult for location providers to save power using the minDistance parameter, so minTime should be the primary tool to conserving battery life.

If your application wants to passively observe location updates triggered by other applications, but not consume any additional power otherwise, then use the PASSIVE_PROVIDER This provider does not actively turn on or modify active location providers, so you do not need to be as careful about minTime and minDistance. However if your application performs heavy work on a location update (such as network activity) then you should select non-zero values for minTime and/or minDistance to rate-limit your update frequency in the case another application enables a location provider with extremely fast updates.

In case the provider is disabled by the user, updates will stop, and a provider availability update will be sent. As soon as the provider is enabled again, location updates will immediately resume and a provider availability update sent. Providers can also send status updates, at any time, with extra's specific to the provider. If a callback was supplied then status and availability updates are via onProviderDisabled(String),onProviderEnabled(String) or onStatusChanged(String, int, Bundle). Alternately, if a pending intent was supplied then status and availability updates are broadcast intents with extra keys of KEY_PROVIDER_ENABLED or KEY_STATUS_CHANGED.

If a LocationListener is used but with no Looper specified then the calling thread must already be a Looper thread such as the main thread of the calling Activity. If a Looper is specified with a LocationListener then callbacks are made on the supplied Looper thread.

Prior to Jellybean, the minTime parameter was only a hint, and some location provider implementations ignored it. From Jellybean and onwards it is mandatory for Android compatible devices to observe both the minTime and minDistance parameters.

Requires the ACCESS_COARSE_LOCATION or ACCESS_FINE_LOCATION permissions.

Parameters
`minTime`	`long`: minimum time interval between location updates, in milliseconds
`minDistance`	`float`: minimum distance between location updates, in meters
`criteria`	`Criteria`: contains parameters for the location manager to choose the appropriate provider and parameters to compute the location
`intent`	`PendingIntent`: a `PendingIntent` to be sent for each location update

Throws
`IllegalArgumentException`	if criteria is null
`IllegalArgumentException`	if intent is null
`SecurityException`	if no suitable permission is present
