title: Custom objects Facebook android open graph
body: <p>I am trying to create custom object using facebook SDK like this:</p>
  
  <pre><code>Bundle params = new Bundle();
  params.putString("type", "android_themes:background");
  params.putString("url", "http://samples.ogp.me/471503979602314");
  params.putString("title", "Sample Background");
  params.putString("description", "");
  
  Request request = new Request(
      Session.getActiveSession(),
      "me/objects/android_themes:background",
      params,
      HttpMethod.POST
  );
  Response response = request.executeAndWait();
  // handle the response
  </code></pre>
  
  <p>But I am keep getting this error:</p>
  
  <blockquote>
    <p>{Response:  responseCode: 400, graphObject: null, error: {HttpStatus:
    400, errorCode: 2500, errorType: OAuthException, errorMessage: Cannot
    specify type in both the path and query parameter.},
    isFromCache:false}</p>
  </blockquote>
  
  <p>Any ideas what is this mean? And what will I get when I be able to do it right? I am not so sure...
  P.S
  Publishing actions on my predefined objects works fine, just this problem.</p>
