    <p>I suggest reading the tutorials provided with android-api.</p> <p>Here is some random example which uses DefaultHttpClient, found by simple text-search in examples-folder.</p> <p>EDIT: The sample-source was not intended to show something. It just requested the content of the url and stored it as string. Here is an example which shows what it loaded (as long as it is string-data, like an html-, css- or javascript-file):</p> <p><strong>main.xml</strong></p> <pre><code> &lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;TextView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/textview" android:layout_width="fill_parent" android:layout_height="fill_parent" /&gt; </code></pre> <p><strong>in onCreate of your app add:</strong></p> <pre><code> // Create client and set our specific user-agent string HttpClient client = new DefaultHttpClient(); HttpGet request = new HttpGet("http://stackoverflow.com/opensearch.xml"); request.setHeader("User-Agent", "set your desired User-Agent"); try { HttpResponse response = client.execute(request); // Check if server response is valid StatusLine status = response.getStatusLine(); if (status.getStatusCode() != 200) { throw new IOException("Invalid response from server: " + status.toString()); } // Pull content stream from response HttpEntity entity = response.getEntity(); InputStream inputStream = entity.getContent(); ByteArrayOutputStream content = new ByteArrayOutputStream(); // Read response into a buffered stream int readBytes = 0; byte[] sBuffer = new byte[512]; while ((readBytes = inputStream.read(sBuffer)) != -1) { content.write(sBuffer, 0, readBytes); } // Return result from buffered stream String dataAsString = new String(content.toByteArray()); TextView tv; tv = (TextView) findViewById(R.id.textview); tv.setText(dataAsString); } catch (IOException e) { Log.d("error", e.getLocalizedMessage()); } </code></pre> <p>This example now loads the content of the given url (the OpenSearchDescription for stackoverflow in the example) and writes the received data in an TextView.</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).
