- Establish VPN connection using any VPN app. VpnService.prepare() will return an intent for the "Connection request" system activity. Once user accepts it, VPN connection can be established successfully.
- Uninstall VPN app.
- Re-install the same VPN app.
- Now VpnService.prepare() returns null, as if the VPN service has been already prepared.
- Now VpnService.protect() returns false and VPN connection fails.
