I want to create an application that connects to a vpn server. I have the address, username and passowrd of the server, and I want to use android vpnservice for this. I know there are a lot of questions about vpn in this forum, but they usually refer to using an open source library called ics-openvpn or using the Android hidden library.
So I do not want this, I want to implement it myself, but, unfortunately, I know very little about vpn. Therefore, please tell me where to start, what steps are and what Android library exists for these steps.
