abstract member GetLastKnownLocation : string -> Android.Locations.Location
override this.GetLastKnownLocation : string -> Android.Locations.Location

Parameters

provider
String

a provider listed by #getAllProviders()

Returns

the last known location for the given provider, or null if not available

Attributes

Exceptions

if no suitable permission is present

if provider is null or doesn't exist

Remarks

Gets the last known location from the given provider, or null if there is no last known location. The returned location may be quite old in some circumstances, so the age of the location should always be checked.

This will never activate sensors to compute a new location, and will only ever return a cached location.

See also #getCurrentLocation(String, CancellationSignal, Executor, Consumer) which will always attempt to return a current location, but will potentially use additional power in the course of the attempt as compared to this method.
