    <p>I'm creating an Android app that should do the following;</p> <ol> <li>Use a form on a https (SSL!) page to login and receive a cookie</li> <li>Issue httpGET actions to get html</li> <li>parse that html and show it in a view, list or something.</li> </ol> <p>I've been fooling around with Jsoup, httpUnit and HTMLUnit for quite some time now, but I'm running in to several problems;</p> <p>A. Login is fine, works.. (I get the website's welcome page) but then, when I issue a GET statement (and include the cookie), I am redirected to the login form. So the response html is not what I expected. (might have something to do with a keepalivestrategy?)</p> <p>B. InputBuffers are too small to receive entire HTML pages and set them up for parsing.</p> <p>NB : I do not have control over the webserver</p> <p>I'm totally new at this, so a tutorial or code snippets would be helpful.</p> <p>For instance, this is what I use to login to the website :</p> <pre><code>public int checkLogin() throws Exception { ArrayList&lt;NameValuePair&gt; data = new ArrayList&lt;NameValuePair&gt;(); data.add(new BasicNameValuePair("userid", getUsername())); data.add(new BasicNameValuePair("password", getPassword())); data.add(new BasicNameValuePair("submit_login", "Logmein")); Log.d(TAG, "Cookie name : " + getCookieName()); Log.d(TAG, "Cookie cont : " + getCookie()); HttpPost request = new HttpPost(BASE_URL); request.getParams().setBooleanParameter(CoreProtocolPNames.USE_EXPECT_CONTINUE, false); request.getParams().setParameter("http.protocol.handle-redirects",false); request.setEntity(new UrlEncodedFormEntity(data, "UTF-8")); HttpResponse response; httpsclient.getCookieStore().clear(); List&lt;Cookie&gt; cookies = httpsclient.getCookieStore().getCookies(); Log.d(TAG, "Number of Cookies pre-login : " + cookies.size()); response = httpsclient.execute(request); cookies = httpsclient.getCookieStore().getCookies(); Log.d(TAG, "Number of Cookies post-login : " + cookies.size()); String html = ""; // Problem : buffer is too small! InputStream in = response.getEntity().getContent(); BufferedReader reader = new BufferedReader(new InputStreamReader(in)); StringBuilder str = new StringBuilder(); String line = null; while ((line = reader.readLine()) != null) { str.append(line); } in.close(); html = str.toString(); Document doc = Jsoup.parse(html); Log.v(TAG, "Ik heb nu dit : " + doc.toString()); if (cookies.size() &gt; 0){ storeCookie(cookies.get(0).getName(), cookies.get(0).getValue()); return MensaMobileActivity.REQUEST_SUCCESS; } else { return MensaMobileActivity.REQUEST_ERROR; } } </code></pre>

    1. COQ: your web client is Android, it's talking to an external web server, correct? You have control over the web server, correct? Is it Apache or IIS? Q: Where do Jsoup, httpUnit and HTMLUnit fit into "Android"? Please clarify a bit.

    3. COOK - you're simply trying to code an HTTP client on Android, correct? If you're not already using it, the Apache HTTP library is probably your best bet. For example: http://masl.cis.gvsu.edu/2010/04/05/android-code-sample-asynchronous-http-connections/ If you have any further questions, please post back any code with specific problems.

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.
