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
