title: Error in obtaining public access token for Mobli
body: <p>I am having is issues in obtaining the public access token for my app. I am getting the following error:
  05-26 14:43:17.194: D/Mobli(1219): Response {"error":"invalid_request","error_description":"The request includes an unsupported parameters","error_uri":"http://dev.mobli.com/error/invalid_request"}</p>
  
  <p>The code that I am using to make the request is as follows:</p>
  
  <pre><code>Mobli mobli = new Mobli(ID, SECRET);  
  SampleRequestListener mobliListner =  new SampleRequestListener();
  runner = new AsyncMobliRunner(mobli);  
  runner.obtainPublicToken(mobliListner, null);
  
  public class SampleRequestListener extends BaseRequestListner {
      public void onComplete(final String response, final Object state) {
          try {
              // process the response here: executed in background thread
              Log.d("Mobli", "Response " + response.toString());
          } catch (MobliError e) {
              Log.w("Mobli Error", "Error" + e.getMessage());
          }
      }
   }
  </code></pre>
  
  <p>Any idea what might be wrong with the code?</p>
