How to check the VPN setting created by an app on an Android device? Many VPN apps would create VPN profiles on the Android device. Unlike VPN profiles create by the user, they cannot be edited, and therefore the user cannot see the setting of said profile. With a rooted device, is there a way to hunt down such profile and read the setting in file?

On iOS devices, the VPN settings are saved in /var/preferneces/com.apple.networkextension.plist file. What is the path to an Android VPN settings?
I know this was asked a while ago... but I am working on this right now so I thought I'd share what I learned so far.

In iOS, a VPN profile defines settings that the OS uses to then initiate a VPN connection.  Everything is managed by the OS, so it would make sense that all of the VPN profiles would be in one location.

In Android, developers can create their own vpn clients instead of using the OS's.  They call into Android API's to raise a virtual adapter that redirects all traffic to their VPN service which they develop and configure to do whatever they like.  VPN connection settings depend on the app and any locally stored data would be part of that app's private data storage.

An example of this can be seen with the OpenVPN client for android.  All of the settings for your VPN connection will be in an openVPN config file that you can load from within the app and you use the app to initiate the connection and change settings.
