1 手機要有root權(quán)限
2 下載tcpdump
android模擬器上linux里面有的會自帶糠聪。
3 adb push c:\wherever_you_put\tcpdump /data/local/tcpdump
4 adb shell chmod 6755 /data/local/tcpdump
5 adb shell, su獲得root權(quán)限
6 cd /data/local
7 ./tcpdump -i any -p -s 0 -w /sdcard/capture.pcap
命令參數(shù)：
# "-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 在電腦上用wireshark打開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:
只監(jiān)聽http
adb shell tcpdump -X -n -s 0 port 80
根據(jù)以上的信息，寫一個bat去執(zhí)行（tcpdump文件必須在當前目錄里）。
開始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
下載tcpdump文件到電腦
adb pull /sdcard/capture.pcap capture.pcap
問題：有些機器root后通過adb shell 后歼争，默認不是root用戶淹父，需要輸入 su才能切換到root萧落，這樣在執(zhí)行批處理會有問題端逼，解決方法如下
adb shell "su -c 'sleep 1'"
adb start-server
adb push tcpdump /data/local/tcpdump
因沒有root權(quán)限導(dǎo)致的問題
adb shell su -c "/data/local/tmp/tcpdump -i any -p -s 0 -w /sdcard/netCapture.pcap"
