    <p>I want some help; I actually have to read and use the content of some website in an Android app. I followed some tutorials but in vain. Someone can help me here.</p> <p><strong>Updated:</strong></p> <p>I actually have used two different codes to get the content of a website but they did not work for me</p> <pre><code>public static String connect(String url) { String result = "bubububu" ; HttpClient httpclient = new DefaultHttpClient(); // Prepare a request object HttpGet httpget = new HttpGet(url); // Execute the request HttpResponse response; try { response = httpclient.execute(httpget); // Examine the response status Log.i("Praeda",response.getStatusLine().toString()); // Get hold of the response entity HttpEntity entity = response.getEntity(); // If the response does not enclose an entity, there is no need // to worry about connection release if (entity != null) { // A Simple JSON Response Read InputStream instream = entity.getContent(); result= convertStreamToString(instream); // now you have the string representation of the HTML request instream.close(); return result ; } } catch (Exception e) { e.getMessage() ; } return result ; } private static String convertStreamToString(InputStream is) { /* * To convert the InputStream to String we use the BufferedReader.readLine() * method. We iterate until the BufferedReader return null which means * there's no more data to read. Each line will appended to a StringBuilder * and returned as String. */ BufferedReader reader = new BufferedReader(new InputStreamReader(is)); StringBuilder sb = new StringBuilder(); String line = null; try { while ((line = reader.readLine()) != null) { sb.append(line + "\n"); } } catch (IOException e) { e.printStackTrace(); } finally { try { is.close(); } catch (IOException e) { e.printStackTrace(); } } return sb.toString(); } public static String connect(String url) { String result = "bubububu" ; HttpClient httpclient = new DefaultHttpClient(); // Prepare a request object HttpGet httpget = new HttpGet(url); // Execute the request HttpResponse response; try { response = httpclient.execute(httpget); // Examine the response status Log.i("Praeda",response.getStatusLine().toString()); // Get hold of the response entity HttpEntity entity = response.getEntity(); // If the response does not enclose an entity, there is no need // to worry about connection release if (entity != null) { // A Simple JSON Response Read InputStream instream = entity.getContent(); result= convertStreamToString(instream); // now you have the string representation of the HTML request instream.close(); return result ; } } catch (Exception e) { e.getMessage() ; } return result ; } private static String convertStreamToString(InputStream is) { /* * To convert the InputStream to String we use the BufferedReader.readLine() * method. We iterate until the BufferedReader return null which means * there's no more data to read. Each line will appended to a StringBuilder * and returned as String. */ BufferedReader reader = new BufferedReader(new InputStreamReader(is)); StringBuilder sb = new StringBuilder(); String line = null; try { while ((line = reader.readLine()) != null) { sb.append(line + "\n"); } } catch (IOException e) { e.printStackTrace(); } finally { try { is.close(); } catch (IOException e) { e.printStackTrace(); } } return sb.toString(); } </code></pre> <p>And</p> <pre><code>private String DownloadText(String URL) { int BUFFER_SIZE = 2000; InputStream in = null; try { in = OpenHttpConnection(URL); } catch (IOException e1) { // TODO Auto-generated catch block e1.printStackTrace(); return ""; } InputStreamReader isr = new InputStreamReader(in); int charRead; String str = ""; char[] inputBuffer = new char[BUFFER_SIZE]; try { while ((charRead = isr.read(inputBuffer))&gt;0) { //---convert the chars to a String--- String readString = String.copyValueOf(inputBuffer, 0, charRead); str += readString; inputBuffer = new char[BUFFER_SIZE]; } in.close(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); return ""; } return str; } private InputStream OpenHttpConnection(String urlString) throws IOException { InputStream in = null; int response = -1; URL url = new URL(urlString); URLConnection conn = url.openConnection(); if (!(conn instanceof HttpURLConnection)) throw new IOException("Not an HTTP connection"); try{ HttpURLConnection httpConn = (HttpURLConnection) conn; httpConn.setAllowUserInteraction(false); httpConn.setInstanceFollowRedirects(true); httpConn.setRequestMethod("GET"); httpConn.connect(); response = httpConn.getResponseCode(); if (response == HttpURLConnection.HTTP_OK) { in = httpConn.getInputStream(); } } catch (Exception ex) { throw new IOException("Error connecting"); } return in; } </code></pre> <p>Both of these give me exception. The <strong>1st one</strong> gives exception at response = httpclient.execute(httpget) and exception.getMessage() is "null" while the <strong>2nd one</strong> gives exception at httpConn.setAllowUserInteraction(false) and exception.getMessage() is Error connecting. Even I have used Internet permissions in menifest file</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.

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).
