How to update OpenVpn SDK

[AliEasy]

Hi First of all thank you very much for your grate source code and tutorial As you mentioned in the readme file

this app uses an older version of the OpenVPN SDK

How can I update the sdk myself? I mean I do not understand the files inside vpnLib inside the android module of source code. how can I generate aidl and so files?

Even I tried upgrading the libs or using newer OpenVPN packegs that are available on pub.dev but then this free servers stopped working.

So if you use newer version then you need to install your own servers and the try (and if you're willing to install your own servers then I will highly recommend you to use wireguard instead of OpenVPN).
