Due to a generator limitation, Intent.getParcelableExtra() isn't bound.
Consequently, you'll need to use JNI to invoke this member (untested):
IntPtr getParcelableExtra = JNIEnv.GetMethodID (arg1.Class.Handle,
"getParcelableExtra",
"(Ljava/lang/String;)Landroid/os/Parcelable;");
IntPtr _ni = JNIEnv.CallObjectMethod (arg1.Handle, getParcelableExtra,
new JValue (new Java.Lang.String
(ConnectivityManager.ExtraNetworkInfo)));
NetworkInfo networkInfo = new NetworkInfo (_ni);
