TrafficStats.getTotalRxBytes 不计算 videoview 的流量
我正在制作一个播放在线视频的软件，并且我正在尝试向该软件添加流量统计功能。我尝试使用 TrafficStats 和 getUidRxBytes 函数。但是，它不计算视频视图的净流量。 像下面的代码一样，我可以看到rx（由getTotalRxBytes返回）增加了很多，但myapprx（由getUidRxBytes返回）没有改变。
int uid = VideoViewPlayer.this.getApplicationInfo().uid;
long rx = TrafficStats.getTotalRxBytes();
long tx = TrafficStats.getTotalTxBytes();
long myapprx = TrafficStats.getUidRxBytes(uid);
long myapptx = TrafficStats.getUidTxBytes(uid);
String info = "uid:"+uid+" rx:"+rx+" tx:"+tx+" myrx:"+myapprx+" mytx:"+myapptx;
更新
首先感谢您的评论给了我重要的线索。我正在尝试找到负责流媒体的 uid。我使用以下代码。但是我找不到消耗流量的进程。
List<ActivityManager.RunningAppProcessInfo> appProcessList = am.getRunningAppProcesses();
ActivityManager.RunningAppProcessInfo info=null;
//List<ActivityManager.RunningServiceInfo> appProcessList = am.getRunningServices(100);
//ActivityManager.RunningServiceInfo info = null;
strinfo = "";
long max =0;
for(int i=0;i<appProcessList.size();++i)
{
info = appProcessList.get(i);
String key = info.processName+"_" +info.uid;
if(mNetTraffic.containsKey(key))
{
long myrx = TrafficStats.getUidRxBytes(info.uid);
long lastrx = mNetTraffic.get(key).longValue();
mNetTraffic.put(key, new Long(myrx));
if(myrx-lastrx>max && myrx - lastrx>0)
{
max = myrx-lastrx;
strinfo = key +":"+max;
}
}else
{
long myrx = TrafficStats.getUidRxBytes(info.uid);
mNetTraffic.put(key, new Long(myrx));
}
}
//trying to watch the key and max and find process and uid, sadly cant find it
i'm making a soft to play online video, and i'm trying to add a traffic statistic feature tot the soft. I try to use TrafficStats and getUidRxBytes function. however, it doesnt count the videoview's net traffic.
Like the following code ,i can see the rx(return by getTotalRxBytes) increase a lot, but the myapprx(return by getUidRxBytes) doesnt change.
int uid = VideoViewPlayer.this.getApplicationInfo().uid;
long rx = TrafficStats.getTotalRxBytes();
long tx = TrafficStats.getTotalTxBytes();
long myapprx = TrafficStats.getUidRxBytes(uid);
long myapptx = TrafficStats.getUidTxBytes(uid);
String info = "uid:"+uid+" rx:"+rx+" tx:"+tx+" myrx:"+myapprx+" mytx:"+myapptx;
UPDATE
Thanks first, your comment gives me important clue. And I'm trying to find the uid responsable for steaming media. I use the following code.However i cannt find the process that comsume the traffic.
List<ActivityManager.RunningAppProcessInfo> appProcessList = am.getRunningAppProcesses();
ActivityManager.RunningAppProcessInfo info=null;
//List<ActivityManager.RunningServiceInfo> appProcessList = am.getRunningServices(100);
//ActivityManager.RunningServiceInfo info = null;
strinfo = "";
long max =0;
for(int i=0;i<appProcessList.size();++i)
{
info = appProcessList.get(i);
String key = info.processName+"_" +info.uid;
if(mNetTraffic.containsKey(key))
{
long myrx = TrafficStats.getUidRxBytes(info.uid);
long lastrx = mNetTraffic.get(key).longValue();
mNetTraffic.put(key, new Long(myrx));
if(myrx-lastrx>max && myrx - lastrx>0)
{
max = myrx-lastrx;
strinfo = key +":"+max;
}
}else
{
long myrx = TrafficStats.getUidRxBytes(info.uid);
mNetTraffic.put(key, new Long(myrx));
}
}
//trying to watch the key and max and find process and uid, sadly cant find it

应使用不同的 UID 报告流媒体，因为它实际上是由 Android 内部进程和模块（OpenCORE 或 StageFright，具体取决于 Android 版本）进行流式传输和播放。
Streaming media should be reported for a different UID, as it is actually streamed and played by an Android internal process and module (OpenCORE or StageFright, depending on Android version).
我遇到了同样的问题，并设法找出该进程具有流媒体的 UID：UID 是 1013

I had the same issue and managed to find out what UID the process has that streams media: the UID is 1013
