    <p>Can anyone help me in writing a program that will connect to site, log me in, and get content of the logged site? I want it to work for site <a href="http://www.imperiaonline.org" rel="nofollow">http://www.imperiaonline.org</a> There are so many redirects and POST requests that I don't know if it is possible. Please help me.</p> <p>I've tried something like this, but it doesn't work...</p> <pre><code> dateFormat = new SimpleDateFormat(DATE_FORMAT); store = new ArrayList&lt;Map&lt;String, String&gt;&gt;(); String uRL = "http://www.imperiaonline.org"; StringBuilder response = new StringBuilder(); Log.v("Execute", "execute url:" + uRL); try { URL url = new URL(uRL); HttpURLConnection httpconn = (HttpURLConnection) url .openConnection(); if (sCookie != null &amp;&amp; sCookie.length() &gt; 0) { httpconn.setRequestProperty("Cookie", sCookie); } if (httpconn.getResponseCode() == HttpURLConnection.HTTP_OK) { BufferedReader input = new BufferedReader( new InputStreamReader(httpconn.getInputStream()), 8192); String strLine = null; while ((strLine = input.readLine()) != null) { response.append(strLine); } input.close(); } String headerName = null; for (int i = 1; (headerName = httpconn.getHeaderFieldKey(i)) != null; i++) { if (headerName.equalsIgnoreCase(SET_COOKIE)) { Map&lt;String, String&gt; cookie = new HashMap&lt;String, String&gt;(); StringTokenizer st = new StringTokenizer( httpconn.getHeaderField(i), COOKIE_VALUE_DELIMITER); // the specification dictates that the first name/value pair // in the string is the cookie name and value, so let's // handle // them as a special case: if (st.hasMoreTokens()) { String token = st.nextToken(); String name = token.substring(0, token.indexOf(NAME_VALUE_SEPARATOR)); String value = token.substring( token.indexOf(NAME_VALUE_SEPARATOR) + 1, token.length()); store.add(cookie); cookie.put(name, value); } while (st.hasMoreTokens()) { String token = st.nextToken(); cookie.put( token.substring(0, token.indexOf(NAME_VALUE_SEPARATOR)) .toLowerCase(), token.substring( token.indexOf(NAME_VALUE_SEPARATOR) + 1, token.length())); } } } } catch (Exception e) { e.printStackTrace(); } for (int i = 0; i &lt; store.size(); ++i) { for (String element : store.get(i).keySet()) { Log.i("ARR", element); } } Log.i("HTML", response.toString()); try { StringBuilder postDataBuilder = new StringBuilder().append("uname=").append(URLEncoder.encode("zygmunter", "UTF8")); postDataBuilder.append("password=").append(URLEncoder.encode("zygmunter", "UTF8")); byte[] postData = null; postData = postDataBuilder.toString().getBytes(); URL url = new URL("http://www99.imperiaonline.org/imperia/game_v5/game/ajax_login.php"); HttpURLConnection co = (HttpURLConnection) url.openConnection(); co.setDoOutput(true); co.setRequestMethod("POST"); co.setRequestProperty("Content-Length", Integer.toString(postData.length)); co.setUseCaches(false); OutputStream out = co.getOutputStream(); out.write(postData); out.close(); response = new StringBuilder(); if (co.getResponseCode() == HttpURLConnection.HTTP_OK) { BufferedReader input = new BufferedReader( new InputStreamReader(co.getInputStream()), 8192); String strLine = null; while ((strLine = input.readLine()) != null) { response.append(strLine); } input.close(); } String resp = response.toString(); Log.i("WYNIK", resp); } catch (IOException ioe) { ioe.printStackTrace(); } </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).
