Hello I have my own OpenVPN server on a RPI, and was wondering if I could somehow get an android OpenVPN client with Handler Integrated, so I could use the free traffic sites (facebook etc) in the handler to access my home fast internet through my OpenVPN server without paying Mobile Data to my carrier.
Does anyone have an apk for it or know how I can do make that myself?
Other ways to do the same thing are appreciated too

Thank you in advance.
