ADB：

adb devices： 失败时使用下一句查询5037端口被占用情况,

netstat -ano | findstr 5037: 然后查看占用的PID，关闭占用程序。

TCPDUMP抓包：

1. 下载tcpdump   http://download.csdn.net/detail/happylisher/8035645

3. adb push c:\wherever_you_put\tcpdump /data/local/tcpdump

4. adb shell chmod 6755 /data/local/tcpdump

5, adb shell,   su获得root权限

6， cd /data/local

7， ./tcpdump -i any -p -s 0 -w /sdcard/capture.pcap

命令参数：

        # "-i any": listen on any network interface

　　# "-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 ...

8,  adb pull /sdcard/capture.pcap d:/

9,  在电脑上用wireshark打开capture.pcap即可分析log

Execute the following if you would like to watch packets go by rather than capturing them to a file (-n skips DNS lookups. -s 0 captures the entire packet rather than just the header):  

adb shell tcpdump -n -s 0   

Typical tcpdump options apply. For example, if you want to see HTTP traffic:  

只监听http  

adb shell tcpdump -X -n -s 0 port 80

根据以上的信息，写一个bat去执行（tcpdump文件必须在当前目录里）。

开始tcpdump 

adb push tcpdump /data/local/tcpdump

adb shell chmod 6755 /data/local/tcpdump

adb shell rm -r /sdcard/capture.pcap

adb shell  /data/local/tcpdump -i any -p -s 0 -w /sdcard/capture.pcap

pause

下载tcpdump文件到电脑 

 adb pull /sdcard/capture.pcap capture.pcap
