Criteria?criteria?=?new?Criteria();
criteria.setAccuracy(Criteria.ACCURACY_LOW);
criteria.setPowerRequirement(Criteria.POWER_LOW);
criteria.setAltitudeRequired(false);
criteria.setBearingRequired(false);

locationManager?=?(LocationManager)context.getSystemService(LOCATION_SERVICE);
provider?=?locationManager.getBestProvider(criteria,?true);
Location?location?=?locationManager.getLastKnownLocation(provider);

在這里你可以和location.getTime()

您還可以添加locationListener以獲取位置更新，因為getLastKnownLocation可以返回 null
