This module is a demo app for a MITM proxy.

Because submodules are used execute:

git pull --recurse-submodules

Load with Android studio and deploy on the device.

A proxy on localhost:9092 must be defined:

Go to "Network & internet" -> "WiFi" -> Edit the WiFi connection -> Click the Edit (pencil) icon -> "Advances options"

For mobile data connections the APN settings must be modified to set the proxy.

The LittleProxy-mitm CA must be installed as user credentials (use the file littleproxy-mitm.pem. Go to "Security" -> "Encryption & credentials" -> "Install a certificate"

The Chrome browser is using the user defined CA and will work out of the box. Open Chrome visit a page and check lock icon to inspect the certificate. Opera has to be patched with a network security configuration. Firefox is not using the proxy settings and is also not obeying a patched network security configuration.

Open the Chrome browser and surf any web page.
