    <pre><code>Caused by: android.os.NetworkOnMainThreadException </code></pre> <p>This means that you're doing your HTTP request on the main thread. Since <strong>Android Honeycomb</strong> version, this way isn't good anymore. You've to use a <strong>second thread</strong> (in fact a <code>background thread</code>) to implement your HTTP request. </p> <p>Why ? </p> <p>Because, if you're running your network method in the main thread, the UI is blocked and the user cannot do anything until your method comes to the end. </p> <p>How to : </p> <p>Use an AsyncTask class that <code>extends AsyncTask&lt;String, String, String&gt;</code> and do your stuff in the <code>DoInBackground</code> method. On the <code>OnpostExcute</code>, you can handle the response.</p> <p>See <a href="http://developer.android.com/reference/android/os/AsyncTask.html" rel="nofollow">Android Developers Post</a></p> <p>This is the response of your issue : </p> <pre><code>class Async extends AsyncTask&lt;String, String, String&gt; { @Override protected void onPreExecute() { super.onPreExecute(); progressDialog = new ProgressDialog(MyActivity.this); progressDialog.setTitle("Merci de patienter"); progressDialog.setMessage("Chargement en cours"); progressDialog.setCancelable(false); progressDialog.setIndeterminate(true); progressDialog.show(); } @Override protected String doInBackground(String... aurl) { try { HttpClient client = new DefaultHttpClient(); HttpGet get = new HttpGet("http://localhost"); HttpResponse response = client.execute(get); StatusLine status = response.getStatusLine(); String data = status.toString(); return data; } catch (Exception e) {} return null; } @Override protected void onPostExecute(String result) { if (progressDialog!=null) { progressDialog.dismiss(); } tvStatus.setText(result); } } @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.json); tvStatus = (TextView) findViewById(R.id.tvStatus); new Async().execute(); } </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).
