    <p>I'm writing a simple HttpClient in Android because I need to make various POST requests in succession. I first do a HttpGet and than the fisrt HttpPost. I can retrieve the HTML of the first GET and of the first POST. But if I do a new GET or a new POST I obtain a blank response. To clarify my problem I attach the code.</p> <pre><code> DefaultHttpClient httpclient = new DefaultHttpClient(); //FIRST GET TO ACCESS LOGIN MODULE try { HttpGet httpget = new HttpGet("https://site/link_to_access_the_login_form"); HttpResponse response = null; try { response = httpclient.execute(httpget); } catch (ClientProtocolException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } catch (IOException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } HttpEntity entity = response.getEntity(); System.out.println("Login form get: " + response.getStatusLine()); entity.consumeContent(); //FIRST POST TO ACCESS THE RESTRICTED AREA HttpPost httpost = new HttpPost("https://site/login/login.do"); List &lt;NameValuePair&gt; nameValuePairs = new ArrayList &lt;NameValuePair&gt;(6); nameValuePairs.add(new BasicNameValuePair("login", "uid")); nameValuePairs.add(new BasicNameValuePair("password", "pwd")); //additional params httpost.setEntity(new UrlEncodedFormEntity(nameValuePairs, HTTP.UTF_8)); try { response = httpclient.execute(httpost); } catch (ClientProtocolException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } entity = response.getEntity(); System.out.println("Login form get: " + response.getStatusLine()); //entity.consumeContent(); try { String responseTextPost1 = EntityUtils.toString(entity); entity.consumeContent(); } catch (ParseException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } //SECOND POST TO ACCESS A LINK IN THE RESTRICTED AREA httpost = new HttpPost("https://site/role/script.do"); List &lt;NameValuePair&gt; nameValuePairs6 = new ArrayList &lt;NameValuePair&gt;(6); //Parameters... httpost.setEntity(new UrlEncodedFormEntity(nameValuePairs6, HTTP.UTF_8)); try { response = httpclient.execute(httpost); } catch (ClientProtocolException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } System.out.println("Login form get: " + response.getStatusLine()); entity = response.getEntity(); try { String responseTextPost2 = EntityUtils.toString(entity); entity.consumeContent(); } catch (ParseException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } catch.............. </code></pre> <p><strong>responseTextPost2</strong> seems to be blank. Suggestions on how to manage this problem?</p>

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.
