Is socketHandle IntPtr.Zero? > s = Java.Lang.Object.GetObject<BluetoothSocket>( socketHandle, > JniHandleOwnership.TransferLocalRef ); > This doesn't work for me either and throws the NullPointerException when I > try Socket.Connect(). Is my syntax correct in the Insecure code snippet? What's the full stack trace that you get? Java.Lang.Object.GetObject<T>() should return null if the handle is IntPtr.Zero. - Jon _______________________________________________ Monodroid mailing list Monodroid@lists.ximian.com UNSUBSCRIBE INFORMATION: http://lists.ximian.com/mailman/listinfo/monodroid
