tcpdump

A powerful command-line packet analyzer; and libpcap, a portable C/C++ library for network traffic capture.

How to sniff traffic from Android emulator

Check which AVDs are present

emulator -list-avds

Select your AVD and run (avoid this part if you are running the emulator yet)

emulator -avd <non_production_avd_name> -writable-system -no-snapshot

Install tcpdump on the Android device (download here: https://www.androidtcpdump.com/android-tcpdump/downloads)

adb root
adb remount
adb push /wherever/you/put/tcpdump /system/xbin/tcpdump
adb shell chmod 6755 /system/xbin/tcpdump

Forward an android port to host

adb forward tcp:11111 tcp:11111

Start sniff traffic with tcpdump

adb shell
tcpdump -i wlan0 -s0 -w - | nc -l -p 11111

Connect wireshark to the forwarded port via netcat

nc localhost 11111 | wireshark -k -S -i -
