Install and configure mitmproxy

Install and cofigure Homebrew:

  ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"
  brew update && brew upgrade 

Install mitmproxy:

  brew intall mitmproxy

The first time mitmproxy or mitmdump is run, a set of certificate files for the mitmproxy Certificate Authority are created in the config directory (~/.mitmproxy by default), so run mitmproxy:

  mitmproxy -p 8888

Note!

When running mitmproxy for the first time, you may encounter an issue:

  > mitmproxy
  Error: mitmproxy requires a UTF console environment.
  Set your LANG enviroment variable to something like en_US.UTF-8

This is because you might have unset LANG env:

  > locale                                                                                                                                                                                                         
  LANG=
  LC_COLLATE="C"
  LC_CTYPE="C"
  LC_MESSAGES="C"
  LC_MONETARY="C"
  LC_NUMERIC="C"
  LC_TIME="C"
  LC_ALL=

All you have to do is to add an export to your .zshrc:

  export LC_ALL=en_US.UTF-8  
  export LANG=en_US.UTF-8

Then source your shell configuration:

  source ~/.zshrc

Push the mitmproxy certificate to the device with adb:

  adb push ~/.mitmproxy/mitmproxy-ca-cert.cer /sdcard/Downloads

On the device, go to the Settings –> Security –> Install from storage –> choose mitmproxy-ca-cert from the dropdown

Adjust your pc-to-device network configuration (Genymotion)

Turn off your virtual device and navigate to Genymotion –> Settings –> Network –> Check “Use HTTP Proxy”

Check the ip of your device (look for vboxnet* entry):

In Genymotion’s network configuration, set “HTTP Proxy” to 192.168.56.1 (because of “vboxnet0”) and “Port” to 8888 (because of “mitmproxy -p 8888”) and run the device.

Note!

You can verify the network with Genymotion Configuration App at the Homescreen; “IP Management” section.

You should see your http/https traffic in mitmproxy. Learn to use it! ;)
