Currently you are Trying to access Ui elements or runOnUiThread inside doInBackground in GetProductDetails AsyncTask class . because it’s not possible to access UI elements from doInBackground you can use onPreExecute and onPostExecute for updating UI elements.Change your code as without using runOnUiThread or UI elements inside doInBackground :

      class GetProductDetails extends AsyncTask<String, String, JSONObject> {

        /**
         * Before starting background thread Show Progress Dialog
         * */

        @Override
        protected void onPreExecute() {
            super.onPreExecute();
            tDialog = new ProgressDialog(My_Task.this);
            tDialog.setMessage("Loading task details. Please wait...");
            tDialog.setIndeterminate(false);
            tDialog.setCancelable(true);
            tDialog.show();
        }
   protected JSONObject doInBackground(String... params) {

                   JSONObject my_task 
                    // Check for success tag
                    int success;
                    try {
                        // Building Parameters
                        List<NameValuePair> params = new ArrayList<NameValuePair>();
                        params.add(new BasicNameValuePair("cid", cid));

                        // getting product details by making HTTP request
                        // Note that product details url will use GET request
                        JSONObject json = JSONParser.makeHttpRequest(
                                url_read_mytask, "GET", params);

                        // check your log for json response
                        Log.d("Single Task Details", json.toString());

                        // json success tag
                        success = json.getInt(TAG_SUCCESS);
                        if (success == 1) {
                            // successfully received product details
                            JSONArray my_taskObj = json
                                    .getJSONArray(TAG_MYTASK); // JSON Array

                            // get first product object from JSON Array
                            my_task = my_taskObj.getJSONObject(0);


                        }
                        else
                        {
                            // task with cid not found
                        }
                    } 
                    catch (JSONException e) {
                        e.printStackTrace();
                    }


            return my_task;
        }
        protected void onPostExecute(JSONObject my_task) {
            // dismiss the dialog once got all details

            // task with this cid found
            // Edit Text
             // display task data in EditText

             cus_name_txtbx = (EditText) findViewById(R.id.cus_name_txt);
             cus_name_txtbx.setText(my_task.getString(TAG_NAME));

             contact_no_txtbx = (EditText) findViewById(R.id.contact_no_txt);
             contact_no_txtbx.setText(my_task.getString(TAG_CONTACT));

             ticket_no_txtbx = (EditText) findViewById(R.id.ticket_no_txt);
             ticket_no_txtbx.setText(my_task.getString(TAG_TICKET));

             task_detail_txtbx = (EditText) findViewById(R.id.task_detail_txt);
             task_detail_txtbx.setText(my_task.getString(TAG_TASKDETAIL));
            tDialog.dismiss();
        }

and Change your onCreate code as:

public class My_Task extends Activity {

        TextView cus_name_txt, contact_no_txt, ticket_no_txt, task_detail_txt,attend_by_txts;
        EditText attend_by_txtbx, cus_name_txtbx, contact_no_txtbx, ticket_no_txtbx, task_detail_txtbx;
        Button btnSave;
        Button btnDelete;

////YOUR CODE here

  @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.my_task);


        cus_name_txt = (TextView) findViewById(R.id.cus_name_txt);

        contact_no_txt = (TextView)findViewById(R.id.contact_no_txt);

        ticket_no_txt = (TextView)findViewById(R.id.ticket_no_txt);

        task_detail_txt = (TextView)findViewById(R.id.task_detail_txt);

        attend_by_txts = (TextView)findViewById(R.id.attend_by_txt;

        attend_by_txtbx = (EditText)findViewById(R.id.attend_by_txtbx);
        attend_by_txtbx.setText(attend_by_txt);
        //your code here
