Works even better in Android 6.0 With Android 6.0  the VPN settings interface now shows OpenConnect as an option. It can be opened or disconnected from there  which is good if a connection is unstable and you want to retry it. However  the best change is the VPN Service API dialog (the one that confirms your connection on Android 4.0 or later) is gone after a one-time popup on the very first time you use OpenConnect. Now  subsequent times (even after rebooting) can connect without any prompts whatsoever!
