    <p>You are trying to do network tasks on the UI thread. This is not allowed. You must do the network requests in a separate thread i.e extend AsyncTask</p> <p>I will post the code, only because it is a tutorial and I happened to look at this myself some time ago. You can see that AsyncTask is used:</p> <pre><code>public class HTTPGetter extends Activity implements OnClickListener { TextView tvHttp; BufferedReader in = null; EditText ethttp; Button bhttp; String returned, strhttp; @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.httpex); tvHttp = (TextView) findViewById(R.id.tvHTTP); bhttp = (Button) findViewById(R.id.bhttp); ethttp = (EditText) findViewById(R.id.ethttp); bhttp.setOnClickListener(this); } private class HTTPGet extends AsyncTask&lt;String, Void, String&gt; { BufferedReader in = null; String returned = null; @Override protected String doInBackground(String... params) { try { HttpClient client = new DefaultHttpClient(); URI website = new URI(strhttp); HttpGet request = new HttpGet(); request.setURI(website); HttpResponse response = client.execute(request); in = new BufferedReader(new InputStreamReader(response .getEntity().getContent())); StringBuffer sb = new StringBuffer(""); String l = ""; String nl = System.getProperty("line.separator"); while ((l = in.readLine()) != null) { sb.append(l + nl); } in.close(); returned = sb.toString(); } catch (ClientProtocolException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } catch (URISyntaxException e) { e.printStackTrace(); } return null; } @Override protected void onPostExecute(String result) { super.onPostExecute(result); tvHttp.setText(returned); } } @Override public void onClick(View v) { switch (v.getId()) { case R.id.bhttp: strhttp = ethttp.getText().toString(); HTTPGet test = new HTTPGet(); try { test.execute(strhttp); } catch (Exception e) { e.printStackTrace(); } break; } } } </code></pre>

    2. COIt works I've just tested it again. Make sure you have <uses-permission android:name="android.permission.INTERNET" /> Also make sure the name of the class matches the activity name in your manifest. For example you may need to change the class name HTTPGetter back to MainActivity. Also make sure the url has http:// before the address that you are requesting.. Also make sure all your references to your xml layout are correct and your setting the correct xml file as your content view. I really can't help any more than that been as I'm running the app right now!

    3. COyes, it's done. I don't understand why it becomes white. I believe you if you say it's working, but on my side, not. when i click, the text field empties it, so it's probably an empty the returned value which is not correct. maybe give me a link witch works (I already tried many)... I'm hopeless :/

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).
