Tcpdump抓取 Android 网络包

Android平台要抓TCP数据包，可以使用TCPdump工具。

1   下载Android 平台的 Tcpdump
      http://www.tcpdump.org
2   push 到手机中
你需要root权限，
adb root
adb remount
adb push  目录\tcpdump /data/local/tcpdump
adb shell chmod 6755  /data/local/tcpdump

3  抓包
adb shell tcpdump -w /data/capture0.pcap
adb shell tcpdump ip 10.1.2.13 and 10.2.3.12 -w /data/capture1.pcap
或者
adb shell tcpdump -p-vv -s 0 -w /sdcard/capture.pcap
# "-p": disable promiscuous mode (doesn't work anyway)
# "-s 0": capture the entire packet
# "-w": write packets to a file (rather than printing to stdout)
   ... do whatever you want to capture,then ^C to stop it ...
4   导出日志
adb pull /data/capture0.pcap   /home/linghu/
adb pull  /sdcard/capture.pcap  /home/linghu/

5   分析
使用Wireshark 下载wireshark查看数据包，地址是http://www.wireshark.org/download.html。
