get result from async task class cause not responding

Issue

I wrote a class that extend async task; i send data to it and class return a json object

But on pre-execute function on async task not working and my program go in not responding mode until class finish its job

public class async_Task extends AsyncTask<Void, Void, JSONObject>
{
    Context mycontext;
    List<NameValuePair> query_List=new ArrayList<NameValuePair>();
    String  str_URL;

    ProgressDialog  progressDialog;
    JSONObject      jsonObject      =null;
    JSONParser      jsonParser      =new JSONParser();

    public async_Task(Context context,List<NameValuePair> lst_NameValuePairs,String url_String)
    {
        this.mycontext  =context;
        this.query_List =lst_NameValuePairs;
        this.str_URL    =url_String;

        progressDialog  =new ProgressDialog(mycontext, ProgressDialog.THEME_HOLO_LIGHT);

    }
    @Override
    protected void onPreExecute()
    {
        progressDialog.setMessage("wait please...");
        progressDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
        progressDialog.setCancelable(false);
        progressDialog.show();
    }

    @Override
    protected JSONObject doInBackground(Void... arg0)
    {
        try
        {
            jsonObject=jsonParser.store_And_Feedback(str_URL, query_List);
        }
        catch (Exception e)
        {
            try
            {
                jsonObject.put("res_code", "-5");
                jsonObject.put("res", e.getMessage());

            }
            catch (JSONException e1)
            {
                // TODO Auto-generated catch block
                e1.printStackTrace();
            }

        }
        return jsonObject;
    }

    @Override
    protected void onPostExecute(JSONObject args)
    {
        progressDialog.dismiss();
    }

}

and i called async task in my activity

jsonObject=new async_Task(JAct_Singup.this, lst_NameValuePairs, str_Url).execute().get();

i need to get result(jsonobject) form async task and when remove get(); i give this error

Type mismatch: cannot convert from AsyncTask<Void,Void,JSONObject> to JSONObject

Solution

finally i found solutions

1- create new interface class

public interface AsyncResponse
{
    void progressEnd(JSONObject jsonObject);
}

2- declare class in async task class

public class async_Task extends AsyncTask<Void, Void, JSONObject>
{
    public AsyncResponse response   =null;

    @Override
    protected void onPreExecute()
    {
         ....
    }

    @Override
    protected JSONObject doInBackground(Void... arg0)
    {
        ...
        return jsonObject;
    }

    @Override
    protected void onPostExecute(JSONObject args)
    {
        ...
        response.progressEnd(jsonObject);
    }

}

3- implements class or activity from created interface class(AsyncResponse)

public class JAct_Singup extends Activity implements AsyncResponse
{
    .........
    @Override
    public void progressEnd(JSONObject jsonObject)
    {
        ...
    } 
}

each time you call async task class the progressEnd called after finish async task
