//Thanks to https://codeshare.frida.re/@pcipolloni/universal-android-ssl-pinning-bypass-with-frida/
//At the moment, this seems to fix the SSL exceptions, but bypass the proxy itself!
//If you have any idea why Android would ignore the proxy setting completely after the following runs, please email androidbugs@voltagex.org - thanks!
