User Verifier demo shows "waiting for kaa response..."
<p>I am trying to run the UserVerification demo on kaa-0.9.0 Sandbox with android APK as client.</p>

<p>I register an facebook application and successfully configured the facebook user verifier on server. and then I succeed to run APK on emulator and then also login facebook. but it keeps showing <strong>"Waiting for Kaa response..."</strong> and I can't send message.</p>

<p>I was wondering if there is other anything I have to do with the server side? or I have to connect with multiple clients with the same user then I can have interactions?</p>

<p>Thanks,</p>
