I am trying to post on users wall from my application without showing the feed dialog box. I have an activity with an EditText getmessage and a Button with onClick()=postToWall. I am following this question:
Android Facebook Post On Wall Without Dialog Warnings

Here is my code:

public void postToWall(View v){
        String message = getmessage.getText().toString();
        postMessage(message);       
    }

    public void postMessage(String message){
        Log.d("test", "testing post to wall");
        try{
            String response;
            Bundle parameters = new Bundle();
            parameters.putString("message", message);           
            response = facebook.request("me/feed", parameters, "POST");

            Log.d("test", "got response "+response);

            if(response == null || response.equals("")){
                Log.v("Error", "Blank");
            }
        }
        catch(Exception e){
            e.printStackTrace();
        }
    }

Below is the log:

    Starting with 3.0 (I think) the system throws an exception if you attempt to use the network on the Main (UI) thread. They chose to make the system do this to encourage developers not to put long running tasks (such as network operations) on the Main thread.

    In order to fix your problem you need to move your network operations(e.g. calls to postMessage()) to a background thread. There are a few approaches. Check out AsyncTask or look into using Handler / Thread. Many examples can be found online if you search for something like “Android create background threads”

    Also this tutorial made by Lars Vogel is awesome for learning about this stuff.
