android 流量统计功能 的实现

2013-11-06 09:41 429 查看
android.net.TrafficStats
类中,提供了多种静态方法,可以直接调用获取,返回类型均为long型,如果返回等于-1代表 UNSUPPORTED 当前设备不支持统计。

 static long  getUidRxBytes(int uid)  //获取某个网络UID的接受字节数
 static long  getUidTxBytes(int uid) //获取某个网络UID的发送字节数
since device boot。注意,流量是从开机开始算的,这个经过验证了,没有问题,可以上官网上查看。

四个SharedPreferences  :  
long    beforeData(中间值,无固定意义) ,totalData(MOS自安装以来的总流量) ,lastTotalData(MOS上一次发送的总流量,日期变化就会发送)。
String  day
各种操作:
第一次安装:
将安装日期放入缓存,第一次安装中操作;

APP登录后:
加载完缓存后,开启service,登录后操作;

开机后:
发送一个广播,功能只是用来清零beforeData 。
 
Service功能:
每十分钟后查看一次已用流量,用这个值减去beforeData 再与 totalData  存到totalData 里面,然后将这个值赋给beforeData  。  
每次查看已用流量都获取本地日期,然后和存起来的日期day相比,一样的话不进行操作,不一样就发送(totalData- lastTotalData)和 日期 到服务器。然后将最新日期保存到String里,并将此时的totalData保存到lastTotalData里。
服务器端:
接收数据后,插入到数据库中,关键数据:员工 + 日期 + 当日使用总流量 。
 
 
第一次安装:
添加如下代码:
 
sharedPrefer=this.getSharedPreferences("LIULIANG", Context.MODE_WORLD_WRITEABLE);
Editor editor1 = sharedPrefer.edit();
editor1.putString("calendarDate", dateFormat.format(now));
editor1.commit();


登录后,添加如下代码:

//开启定时统计流量的服务
Intent intent = new Intent(mosApp, LiuLiangService.class);
PendingIntent sender = PendingIntent.getService(mosApp, 0, intent, 0);
long firstime = SystemClock.elapsedRealtime();
am = (AlarmManager) mosApp.getSystemService(Context.ALARM_SERVICE);
// 十分钟一个周期,不停的开启服务
am.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP, firstime,
10*60*1000, sender);
//end
