According to the doc VpnService.prepare(context) is used to establish a VPN connection in android, and it's doing the trick in almost all device models except specific ones ( Oppo X9076 Android 5.0 ). As per the logs from within the crashlytics call to VpnService.prepare(context) cause the SDK break internally. Not sure whether it's a device specific issue or what!. below is the log from crashlytics.
Fatal Exception: java.lang.NullPointerException: Attempt to invoke virtual method 'boolean com.android.server.connectivity.Vpn.prepare(java.lang.String, java.lang.String)' on a null object reference

I've given everything, not to exempt an extensive search on the web as well, yet to make a way out. Pl. help me out, I'm stuck here all the way.
