title: Facebook post to wall give exception
body: <p>I want to post text message to my facebook wall. My example code is:</p>
  
  <pre><code>public void postOnMyFacebookWall(String msg) {
      Log.d("Tests", "Testing graph API wall post");
       try {
              String response = facebook.request("me");
              Bundle parameters = new Bundle();
              parameters.putString("message", msg);
              parameters.putString("description", "test test test");
              response = facebook.request("me/feed", parameters, 
                      "POST");
              Log.d("Tests", "got response: " + response);
              if (response == null || response.equals("") || 
                      response.equals("false")) {
                 Log.v("Error", "Blank response");
             }
       } catch(Exception e) {
           e.printStackTrace();
       }
  }
  </code></pre>
  
  <p>I have called authorize function and got access_token before making call to this function. But got the following type of error:</p>
  
  <pre><code>key message expected byte[] but value was a java.lang.String. The default value &lt;null&gt; was returned.
  </code></pre>
  
  <p>And when I see on my facebook wall, the post is visible there too...
  Any idea...???</p>
