    <p>I am trying to implement bonjour/zero conf on my android app. I am using jmDns library for searching the all the available devices. Here is the code that I am using for searching the devices in the same network:</p> <pre><code>public class ListDevices extends ListActivity { JmDNS jmdns; JmDNSImpl impl; MulticastLock lock; protected ServiceListener listener; protected ServiceInfo info; public ListView lv; public ArrayList&lt;String&gt; deviceList; public int cancel = 0; public final static String TAG = "ListDevices"; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); deviceList = new ArrayList&lt;String&gt;(); showAllPrinters(); setListAdapter(new ArrayAdapter&lt;String&gt;(this, android.R.layout.simple_list_item_1, deviceList)); lv = getListView(); lv.setTextFilterEnabled(true); lv.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView&lt;?&gt; parent, View view, int position, long id) { // When clicked, show a toast with the TextView text Toast.makeText(getApplicationContext(), ((TextView) view).getText(), Toast.LENGTH_SHORT).show(); } }); this.listener = new ServiceListener() { public void serviceAdded(ServiceEvent event) { deviceList.add("Service added : " + event.getName() + "." + event.getType()); Log.v(TAG, "Service added : " + event.getName() + "." + event.getType()); } public void serviceRemoved(ServiceEvent event) { deviceList.add("Service removed : " + event.getName() + "." + event.getType()); Log.v(TAG, "Service removed : " + event.getName() + "." + event.getType()); } public void serviceResolved(ServiceEvent event) { deviceList.add("Service resolved: " + event.getInfo()); Log.v(TAG, "Service resolved: " + event.getInfo()); } }; } public void showAllPrinters() { Log.d("ListDevices", "in showAllPrinters"); try { WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE); lock = wifi.createMulticastLock("fliing_lock"); lock.setReferenceCounted(true); lock.acquire(); InetAddress inetAddress = getLocalIpAddress(); jmdns = JmDNS.create(inetAddress, "TEST"); ServiceInfo[] infos = jmdns.list("_http._tcp.local."); if (infos != null &amp;&amp; infos.length &gt; 0) { for (int i = 0; i &lt; infos.length; i++) { deviceList.add(infos[i].getName()); } } else { deviceList.add("No device found."); } impl = (JmDNSImpl) jmdns; } catch (IOException e) { e.printStackTrace(); } } public InetAddress getLocalIpAddress() { try { for (Enumeration&lt;NetworkInterface&gt; en = NetworkInterface .getNetworkInterfaces(); en.hasMoreElements();) { NetworkInterface intf = (NetworkInterface) en.nextElement(); for (Enumeration&lt;InetAddress&gt; enumIpAddr = intf .getInetAddresses(); enumIpAddr.hasMoreElements();) { InetAddress inetAddress = (InetAddress) enumIpAddr .nextElement(); if (!inetAddress.isLoopbackAddress()) { return inetAddress; } } } } catch (SocketException ex) { Log.e("ListDevices", ex.toString()); } return null; } @Override protected void onPause() { super.onPause(); if (isFinishing()) { lock.release(); } } } </code></pre> <p>Basically, I am adding them in a list so that I can display a list of all available devices. Now when I am running this code, I am getting no exception/nothing like error. But on the other hand, nothing is added to my list [PS: there atleast 5-6 PCs and Macs are there in the network.</p> <p>I also tried to get the list from this code:</p> <pre><code>jmdns.addServiceListener("_http._tcp.local.", listener); </code></pre> <p><code>listener</code> is defined in the <code>onCreate</code> of the activity. But this also did not returned any device.</p> <p>Please help, suggest what I am doing wrong here. Any help is appreciated!</p>

    1. COShouldn't you be using this code: if (!inetAddress.isLoopbackAddress() && !inetAddress.isLinkLocalAddress() && inetAddress.isSiteLocalAddress())

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).
