may help you . Within the Asynctask the onPostExecute method is not being called, however, neither are the Logcat prints after the method within the doinbackground. Any ideas? , You should call your asynctask this way:
code :
new AsyncTask().execute("parameter");

will be helpful for those in need You need to initialze delegate. Change the code in myClass constructor.
code :
public myClass(Context context){
      delegate = (AsyncResponse) context;
}

With these it helps This is working for me, check that u use a correct url with protocol (http://www.ursite.com):
code :
private String downloadUrl(String myurl) throws IOException {
        System.out.println("Starting");

        List<NameValuePair> params = new ArrayList<>();
        params.add(new BasicNameValuePair("cus_name", cus_names));
        params.add(new BasicNameValuePair("created_date1", createddate));
        params.add(new BasicNameValuePair("created_date2", created_date));

        InputStream is = null;

        URL url;
        HttpURLConnection connection = null;
        try {
            //Create connection
            url = new URL(myurl);
            connection = (HttpURLConnection) url.openConnection();
            connection.setRequestMethod("POST");
            connection.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
            connection.setRequestProperty("Content-Language", "en-US");
            connection.setUseCaches(false);
            connection.setDoInput(true);
            connection.setDoOutput(true);

            //Send request
            OutputStream os = connection.getOutputStream();
            DataOutputStream wr = new DataOutputStream(os);
            wr.writeBytes("try=this");//replace with your getQuery
            wr.flush();
            wr.close();
            os.close();
            //Get Response
            is = connection.getInputStream();
            BufferedReader rd = new BufferedReader(new InputStreamReader(is));
            String line;
            StringBuffer response = new StringBuffer();

            while ((line = rd.readLine()) != null) {
                response.append(line);
                response.append('\r');
            }
            rd.close();

            System.out.println(response);
            return response.toString();

        } catch (Exception e) {

            e.printStackTrace();
            return null;

        } finally {

            if (connection != null) {
                connection.disconnect();
            }
        }

    }

it helps some times If you are using separate class,you just pass the class via constructor.
For example,
code :
BackGround(Context  context,Class mIntentclass) {
    this.ctx=context;
    this.mIntentclass = mIntentclass;

}
    if(result.equals("success")) {
    Toast.makeText(ctx,"onpost excute",Toast.LENGTH_LONG).show();        
    Intent intent = new Intent(ctx,mIntentclass.class);
    ctx.startActivity(intent);  

}
   Toast.makeText(ctx,result,Toast.LENGTH_LONG).show();
}
BackGround background = new BackGround(context,MainActivity);

it fixes the issue Pass reference to your activity to MakePOSTAsync. The best approach is to store it inside AsyncTask as a WeakReference - this will prevent reference leaks. Also you actually should create an interface, and pass reference to this interface. Each of your activities will implement this interface.
