title: Getting started with Open NFC emulator
body: <p>I would like to get started with developing NFC apps for android. I have started with android recently and I'm finding it a very interesting platform to develop for. Before I go out and invest in an Android device that has a built in NFC reader and purchase tags, I would like to get a feel of how one actually writes code for them.</p>
  
  <p>I found the <a href="http://www.open-nfc.org/android.html" rel="noreferrer">Open NFC Android emulator</a> and it appears to be what I'm looking for. I have downloaded :
  1. The Open NFC for Android
  2. The Open NFC core Edition</p>
  
  <p>After creating an avd that for Open NFC, I followed the instructions.</p>
  
  <p>Now the problem that I face is that in the emulator, when I go to the Wireless Settings and then I enable NFC, It says that there was an error. I have tried setting the IP to 10.0.2.2 and also the IP that I get from ipconfig but to no avail. There's no log that I can see.
  Also I have tried to disable the firewall completely while running it so that it doesn't get blocked accidentally.</p>
  
  <p>As a side note, I would like to mention that I have the Connection Manager Started before I launch the emulator.</p>
  
  <p>Does anybody have experience with Open NFC for Android, If somebody can point me to a better set of instructions I'd be most grateful alternatively If someone could suggest another simulator by which I can try out some sample code and get a better understanding about NFC. </p>
  
  <p>The output of the adb logcat is</p>

  <p>I get the same error when I change the IP to the one obtained with ipconfig.</p>
