  • location – The last known location according to the monitoring system.
Deprecated:use onMonitoringSystemChange(GeofenceHardwareMonitorEvent) instead. NOTE: this API is will remain to be called on Android API 21 and above for backwards compatibility. But clients must stop implementing it when updating their code.
