    <p>Just a clarification beforehand: the URL <code>*SamsungMRDesc.xml</code> is a <em>device descriptor</em>, not a <em>service descriptor</em> as you've written, right?</p> <p>The <code>&lt;SCPDURL&gt;</code> per UPnP spec is "relative to the URL at which the device description is located". So yes, the correct absolute SCPDURL is the second one. But i would be highly surprised if there was really such severe bug in Cling. So to offer some theories:</p> <ol> <li>What do you mean by "no actions being displayed in Cling UPnP" ? Is that some existing example app or your code? Cling itself does not provide any GUI. Might there be a bug in that code?</li> <li>Are you absolutely sure about the <em>device descriptor</em> URL (SamsungMRDesc)? Is it reachable manually, i.e. by simply copy&amp;pasting the URL into web browser?</li> <li>What you see if you copy&amp;paste the SCPDURL into web browser? Are there some <code>&lt;action&gt;</code> nodes under <code>&lt;actionList&gt;</code>?</li> <li>Have you tried to query your Samsung TV with DeviceSpy from <a href="http://opentools.homeip.net/dev-tools-for-upnp" rel="nofollow">Intel Developer Tools</a> ? You can see what an other UPnP stack sees, besides Cling. Furthermore, you can right-click on a Device node as well as Service node and see where DeviceSpy looks for the descriptions.</li> <li>As a last instance, you can sniff what's being sent back and forth with Wireshark. Start with setting Wireshark IP filter to the address of your Samsung TV.</li> </ol> <p>Theories 4 and 5 obviously require a PC connected to the same network as the TV (and your Android).</p>

    1. COThanks for your reply. For your point 1 : I am using teh sample code provided by cling to discover all UPnP services n the network. While I debug , if I move inside teh identified Device object in debugger console no actions are shown. Its showing an empty list.

    2. COPoint 2: Yes I can see the device descriptor URL in browser. For SCPDURL this is not working http://<ip address>:52235/RenderingControl1.xml but this works in a browser http://<ip address>:52235/dmr/RenderingControl1.xml and I can see actionList and actions inside it.

    3. COI just found out that Cling has a standalone application called [Workbench](http://4thline.org/projects/cling/workbench/) which is similar to DeviceSpy. So query your Samsung TV with this Workbench and have a look whether the services and actions are there. If so, you have a problem with your code because Cling apparently does the right thing.

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).
