1、TrafficStats类的使用
以下结论,是自己真机实测的结果,与自己在网上看到的不同,大家可自测验证。
(1)getMobile...方法,获取Gprs/3G流量
(2)getTotal...方法,获取Gprs/3G+Wifi的流量
以上两类方法统计的都是,从打开网络开始,到关闭网络,这一段时间内使用的流量。例如:10点打开,11点关闭,那么getMobileRxBytes方法,回返的是这段时间内Gprs/3G接受到的字节数。
(3)getUid...方法,获取某个网络UID的流量。这类方法,返回的是,从开机到关机,某个网络UID(我理解就是某个应用,如果不对,请在评论中指正)使用的Gprs/3G+Wifi的流量
2、getUid...方法的使用
以下这段代码是网上找的,出处找不到了,希望原作者不要介意啊
- List<PackageInfo> packinfos = pm.getInstalledPackages(PackageManager.GET_UNINSTALLED_PACKAGES | PackageManager.GET_PERMISSIONS);
- for (PackageInfo info : packinfos) {
- String[] premissions = info.requestedPermissions;
- if (premissions != null && premissions.length > 0) {
- for (String premission : premissions) {
- if ("android.permission.INTERNET".equals(premission)) {
- // System.out.println(info.packageName+"访问网络");
- int uid = info.applicationInfo.uid;
- long rx = TrafficStats.getUidRxBytes(uid);
- long tx = TrafficStats.getUidTxBytes(uid);
- if (rx < 0 || tx < 0) {
- System.out.println(info.packageName + "没有产生流量");
- } else {
- System.out.println(info.packageName + "的流量信息:");
- System.out.println("下载的流量" + Formatter.formatFileSize(this, rx));
- System.out.println("上传的流量" + Formatter.formatFileSize(this, tx));
- }
- }
- }
- System.out.println("---------");
- }
- }
3、获取流量信息的Service类
(1)因为两个广播都需要动态注册,所以写成了Service
(2)getMobile...和getTotal...方法获取的都是从打开网络开始,到关闭网络,这一段时间内使用的流量。
因此要在网络正在关闭时获取的就是这段时间的流量,WifiManager.WIFI_STATE_DISABLING表示的就是这个状态
(3)Gprs/3G貌似没有类似的状态,可以被监控到,只有,State.CONNECTED和State.DISCONNECTED。但是处于State.DISCONNECTED这个状态时,getMobile...方法获取到的值就都是0了
所有,我不得不在State.CONNECTED这个状态开始时,开启线程用于获取Gprs/3G的流量,直到我获取的到数据为0时,保存上一次的数据。
如果大家有更好的方法,请务必告诉我啊!
