java - Sending Open Sound Control (OSC) in Android Studio, socket error

I tried to use OSC in android studio, following by "Tutorial: Android OSC Communication" on http://courses.ideate.cmu.edu/physcomp/f14/16-223/tutorial-android-osc-communication/. It uses JavaOSC from Illposed.

However, I got a socket exception error when I created a new OSCPortOut. Can you share some idea of what is happening here? How to solve this.

Android studio 1.5.1
Version 4.4
Many thanks
