If you are doing it from the emulator you can do it like this:

Run <code>emulator -tcpdump emulator.cap -avd my_avd</code> to write all the emulator's traffic to a local file on your PC and then open it in wireshark

You would need to root the phone and cross compile tcpdump or use someone else's already compiled version.

You might find it easier to do these experiments with the emulator, in which case you could do the monitoring from the hosting pc. If you must use a real device, another option would be to put it on a wifi network hanging off of a secondary interface on a linux box running tcpdump.

I don't know off the top of my head how you would go about filtering by a specific process. One suggestion I found in some quick googling is to use strace on the subject process instead of tcpdump on the system.

Note: tcpdump requires root privileges, so you'll have to root your phone if not done already. Here's an ARM <a href="http://www.eecs.umich.edu/~timuralp/tcpdump-arm">binary</a> of tcpdump (this works for my Samsung Captivate). If you prefer to build your own binary, instructions are <a href="http://nerdjusttyped.blogspot.com/2009/03/android-binary-solo.html">here</a> (yes, you'd likely need to cross compile).

Also, check out <a href="http://www.appbrain.com/app/shark-for-root/lv.n3o.shark">Shark For Root</a> (an Android packet capture tool based on tcpdump).

I don't believe tcpdump can monitor traffic by specific process ID. The strace <a href="http://www.mail-archive.com/tcpdump-workers@sandelman.ottawa.on.ca/msg03336.html">method</a> that Chris Stratton refers to seems like more effort than its worth. It would be simpler to monitor specific IPs and ports used by the target process. If that info isn't known, capture all traffic during a period of process activity and then sift through the resulting pcap with Wireshark.

I would like to monitor network traffic of my Android Phone. I was thinking using tcpdump for Android, but I'm not sure if I have to cross-compile for the phone.

Another question is the following, If I want to monitor the trafic data for a certain application, there's any command for doing that?

Monitor network activity in Android Phones

Android

我想监控我的Android手机的网络流量。我在考虑在Android上使用tcpdump，但我不确定是否必须为手机交叉编译。另一个问题是，如果我想监控某个应用程序的传输数据，有什么命令可以做到吗？
