Android programming to obtain network time example analysis

This article illustrates the Android programming method to obtain network time. To share with you for your reference, as follows:

The most common ways to see it online are:

public static void main(String[] args) throws Exception {
  URL url=new URL("http://www.bjtime.cn");// Getting the resource object 
  URLConnection uc=url.openConnection();// Generate connection objects 
  uc.connect(); // A connection 
  long ld=uc.getDate(); // Get the date and time of the site 
  Date date=new Date(ld); // Convert to a standard time object 
  // Gets the hours, minutes and seconds of the time, respectively, and outputs them 
  System.out.print(date.getHours()+" when "+date.getMinutes()+" points "+date.getSeconds()+" seconds ");
}

Principle: by accessing http: / / www bjtime. cn website to obtain

Here's another way to do it: via the Internet or GPS.

The code is as follows:

LocationManager locMan = (LocationManager) this.getSystemService(MainActivity.LOCATION_SERVICE);
// For the recent 1 The last known time 
long networkTS = locMan.getLastKnownLocation(LocationManager.NETWORK_PROVIDER).getTime();
 Or the real-time acquisition time: 
locMan.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, this); // Get the current time 
 When we use requestLocationUpdates When we need to implement LocationListener Interface. 
 in LocationListen The callback onLocationChanged Get the time in the middle 
@Override
public void onLocationChanged(Location location) {
// TODO Auto-generated method stub
long time = location.getTime();
Date date = new Date(time);
System.out.println(time + " NETWORK_PROVIDER " + date);
// System.out.println(STANDARD_TIME + " ");
}
