Receiving error java.lang.IllegalStateException: The content of the adapter has changed but ListView did not receive a notification

Question

I have catch this error "Make sure the content of your adapter is not modified from a background thread Make sure your adapter calls notifyDataSetChanged() when its content changes." sometimes when click on listview onClickListener.

I dont get this everytime. I get this error at random sometime. But i dont understand from where this error is coming. I am using Asynctask.

Here is my Asynctask code,

new AsyncTask() {
    boolean error_server;

    protected void onPreExecute() {
        Asycdialog = new ProgressDialog(ReportingList.this);
        Asycdialog.setMessage("Loading...");
        Asycdialog.setCanceledOnTouchOutside(false);
        Asycdialog.show();
    };

    @Override
    protected Void doInBackground(String... arg0) {
        try {
            arraylist_product_category.clear();
            JSONArray jArray_cate = new JSONArray();
            jArray_cate.put("id");
            jArray_cate.put("name");

            JSONObject fieldsAccumulates_cate = new JSONObject();
            fieldsAccumulates_cate.put("fields", jArray_cate);
            JSONObject jo_cate = odoo.search_read("product.category", fieldsAccumulates_cate);

            JSONArray result_cate = jo_cate.getJSONArray("records");
            if (result_cate.length() > 0) {
                for (int i = 0; i < result_cate.length(); i++) {
                    JSONObject jo1 = result_cate.getJSONObject(i);
                    WorldPopulation wp = new WorldPopulation(jo1.getString("id"), jo1.getString("name"));
                    arraylist_product_category.add(wp);
                }
            } else {
                publishProgress(1);
            }

            //adapter_product_category = new ListViewAdapter(ReportingList.this, arraylist_product_category);
            //adapter_product_category.notifyDataSetChanged();
            is_adapter_product_category_filled = true;
        } catch (Exception e) {
            e.printStackTrace();
            error_server = true;
        }
        return null;
    };

    protected void onProgressUpdate(Integer... values) {
        if (values[0] == 1)
            et_product_category.setText("");
    };

    protected void onPostExecute(Void result) {
        adapter_product_category = new ListViewAdapter(ReportingList.this, arraylist_product_category);
        //is_adapter_product_category_filled = true;
        if(Asycdialog.isShowing())
            Asycdialog.dismiss();
        if (error_server)
            Toast.makeText(getApplicationContext(), "Server not reachable", Toast.LENGTH_LONG).show();
    };
}.execute(null, null, null);

Please help me with this error. What am I doing wrong?
