    <p>Actually I have already applied the AsyncTask but I did it wrongly. Selvin pointed out that I move 'getJSONfromURL' call into doInBackground. And it works!</p> <pre><code>class GetPayPalResult extends AsyncTask&lt;String, String, String&gt; { ListActivity theList = new ListActivity(); private ListView mainListView ; private ProgressDialog pDialog; /* * * Before starting background thread Show Progress Dialog * */ @Override protected void onPreExecute() { super.onPreExecute(); pDialog = new ProgressDialog(CheckOut.this); pDialog.setMessage("Loading Options ..."); pDialog.setIndeterminate(false); pDialog.setCancelable(false); pDialog.show(); } /* * * getting Inbox JSON * */ protected String doInBackground(String... args) { // Building Parameters List&lt;NameValuePair&gt; params = new ArrayList&lt;NameValuePair&gt;(); params.add(new BasicNameValuePair("payKey", payKey)); params.add(new BasicNameValuePair("requestEnvelope.errorLanguage", "en_US")); httppost.setHeader("X-PAYPAL-SECURITY-USERID", "66.whatever.com"); httppost.setHeader("X-PAYPAL-SECURITY-PASSWORD", "6666666"); httppost.setHeader("X-PAYPAL-SECURITY-SIGNATURE", "55546g"); httppost.setHeader("X-PAYPAL-APPLICATION-ID", "APP-80W284485P519543T"); httppost.setHeader("X-PAYPAL-REQUEST-DATA-FORMAT", "NV"); httppost.setHeader("X-PAYPAL-RESPONSE-DATA-FORMAT", "NV"); String result = getJSONfromURL(paypalkeyurl,params); Log.d("Paykey Content: ", result); return null; } /* * * After completing background task Dismiss the progress dialog * * */ protected void onPostExecute(String file_url) { pDialog.dismiss(); } public String getJSONfromURL(String url, List&lt;NameValuePair&gt; params) { InputStream is = null; String result = ""; //Toast.makeText(CouponView.this,"running this", Toast.LENGTH_LONG).show(); // http post try { HttpPost httppost = new HttpPost(url); httppost.setEntity(new UrlEncodedFormEntity(params, HTTP.UTF_8)); HttpResponse response = Client.getInstance().execute(httppost); HttpEntity entity = response.getEntity(); is = entity.getContent(); } catch (Exception e) { Log.e("log_tag", "Error in http connection :" + e.toString()); } // convert response to string try { BufferedReader reader = new BufferedReader(new InputStreamReader( is, "iso-8859-1"), 8); StringBuilder sb = new StringBuilder(); String line = null; while ((line = reader.readLine()) != null) { sb.append(line + "\n"); } is.close(); result = sb.toString(); } catch (Exception e) { Log.e("log_tag", "Error converting result " + e.toString()); } return result; } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
