* consider using {@link #getLastKnownLocation(String)} or {@link #getCurrentLocation(String,

*
* <p>See {@link LocationRequest} documentation for an explanation of various request parameters
* and how they can affect the received locations.
*
* <p>If your application wants to passively observe location updates from all providers, then
* use the {@link #PASSIVE_PROVIDER}. This provider does not turn on or modify active location
* providers, so you do not need to be as careful about minimum time and minimum distance
* parameters. However, if your application performs heavy work on a location update (such as
* network activity) then you should set an explicit fastest interval on your location request
* in case another application enables a location provider with extremely fast updates.
*
* <p>In case the provider you have selected is disabled, location updates will cease, and a
* provider availability update will be sent. As soon as the provider is enabled again, another
* provider availability update will be sent and location updates will resume.
*
* <p>Locations returned from {@link #GPS_PROVIDER} are with respect to the primary GNSS antenna
* position within the device. {@link #getGnssAntennaInfos()} may be used to determine the GNSS
* antenna position with respect to the Android Coordinate System, and convert between them if
* necessary. This is generally only necessary for high accuracy applications.
*
* <p>When location callbacks are invoked, the system will hold a wakelock on your
* application's behalf for some period of time, but not indefinitely. If your application
* requires a long running wakelock within the location callback, you should acquire it
* yourself.
*
* <p>Spamming location requests is a drain on system resources, and the system has preventative
* measures in place to ensure that this behavior will never result in more locations than could
* be achieved with a single location request with an equivalent interval that is left in place
* the whole time. As part of this amelioration, applications that target Android S and above
* may receive cached or historical locations through their listener. These locations will never
* be older than the interval of the location request.
