Question

I am using the following code and trying to post message on facebook wall along with the picture url. Both message and picture url is empty. Can any one find out and direct me in the right direction?

btnPostToWall.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            postToWall();
        }
    });


public void postToWall() {
    Bundle params = new Bundle();

    params.putString("message","test to post");

    params.putString("url", URLEncoder.encode("http://a.espncdn.com/photo/2010/0523/pg2_a_cricket_576.jpg"));

    try {
        String response = facebook.request("me/feed", params, "POST");
    } catch (FileNotFoundException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    } catch (MalformedURLException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    } catch (IOException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    }
    // post on user's wall.
    facebook.dialog(this, "feed", new DialogListener() {

        @Override
        public void onFacebookError(FacebookError e) {
        }

        @Override
        public void onError(DialogError e) {
        }

        @Override
        public void onComplete(Bundle values) {
        }

        @Override
        public void onCancel() {
        }
    });

}

Answer 1

set this permission as public

private String[] PERMISSIONS = new String[]

    { "publish_stream", "read_stream", "offline_access" };

This will check is session exist if yes then it will direct update if not then ask user permission to update on wall.

Button click event

    facebookConnector = new FacebookConnector(APP_ID, activity.getParent(), 
activity.getApplicationContext(),PERMISSIONS);
    if (facebookConnector.getFacebook().isSessionValid())
    {   
         postMessageInThread(position); // see method below 
    }
    else
    {
         SessionEvents.AuthListener listener = new SessionEvents.AuthListener()
    {

@Override
public void onAuthSucceed()
{
     postMessageInThread(position);
}

@Override
public void onAuthFail(String error)
{
}
};  

SessionEvents.addAuthListener(listener);
    facebookConnector.login();
}

This will update your data on wall

private void postMessageInThread(final int position)
    {
        Thread t = new Thread()
        {
            public void run()
            {
                try
                {
                    facebookConnector.postMessageOnWall(
                            "Your Text Data",
                            "Your Email URL","Description");
                    mFacebookHandler.post(mUpdateFacebookNotification);
                } catch (Exception ex)
                {
                    Log.e("", "Error sending msg", ex);
                }
            }
        };
        t.start();
    }

Note: : Here Position is my list record so manage your data according to that.
