Setting up an HTTPS proxy I use proxifier to connect to an HTTPS proxy on the PC, what should I do in order to connect similarly on my Android smartphone?

My Android version is 4.3, Jelly Bean.
Use Drony. You change type in settings from default http to https. Be careful about HTTPS proxy certificate. If it's self signed there is option to trust all certs in settings. But then you can have mitm so it's not very secure. 
There is nice blog about setting up whole configuration.
