Should I setXMLParser() in anywhere ?

hi

how can i get the full xml string of a device ?

(want to insert it in a json object key)

thanks

Here is my step:

1. Start search will do this --> controlpoint.addDevicesChangeListenner(),controlpoint.start() controlpoint.search();
2. WiFi Turn OFF then turn ON will do this -->controlpoint.stop(),controlpoint.start() controlpoint.search();
   3.Then in the same WiFi environment , turn OFF/ON my DLNA device by turns, few times later it crash like the bellow logs:

Hello guys:
I have a problem when using cybergarage lib . The detail error log as follows:

I guess that it is related to searching .However, I have no way to stop it .Anyone has good idea?

Please check your files. There are tons of merge conflicts. E.g. in https://github.com/cybergarage/CyberLink4Java/blob/master/upnp-stack/pom.xml

two years have passed since the last release, is there a new version?
Looking forward to new release

Does this code library support DMR on Android?

The current comments are non-javadoc and therefore do not help when developing. It requires quite some time to actually step into the code to see which effect specific params have.

It would be great to have javadoc compliant comments on methods and classes to ease the development using any Java IDE.

So currently i am trying to connect with speakers which works pretty well for the devices below android Pie. But for the particular devices (Samsung Galaxy S10, vivo,Samsung Galaxy A50) with android pie version i am getting null socket which leads to speakers not found for these particular devices.

Also, I came across weird scenario: when I turned on airplane mode, speaker are getting detected. which is not the correct solution for me.

below is the link on page,
http://www.cybergarage.org/maven/repo/org/cybergarage/cyberlink/cyberlink-core/

I have put together a basic ControlPoint and MediaRenderer, both of which are running on my MacBook. While the ControlPoint is able to see all of the devices in my house (so far), other ControlPoints do not see the MediaRenderer. Specifically, the built-in music players on the Samsung Galaxy S5 and LG V10, as well as other Android Apps, such as BubbleUPnP and UPnP Scanner. The latter two are built on the Cling UPnP stack. A third Android App, AirWire, does find the MediaRenderer, and is able to control it without issue.

At first I thought this might be a problem restricted to Cling-based devices discovering CyberGarage devices, but since the Android music players are unable to find them either, it appears to be a broader issue.

Hi!
For some tv i can't play video. This happened because services sometimes include full path for SCPDURL, sontrolURL, eventSubURL and sometimes include path relative of description file path.
Description file path: /dmr/ddd.xml

urn:schemas-upnp-org:service:AVTransport:1
urn:upnp-org:serviceId:AVTransport

Can you help me?

I have been using this code to control Wemo devices, however run into an issue when calling Device.getAction(); which returns null and results in an inability to control the device.

The root of the issue appears to be in org.cybergarage.upnp.Device in the getAbsoluteURL(String, String, String) method. The method is called with:
urlString="/timesyncservice.xml"
baseURLString=""
locationURLStr="http://:49153/setup.xml"

The method returns a string: "http://:49153/setup.xml/timesyncservice.xml", which is incorrect. It should return "http://:49153/timesyncservice.xml". It appears the only validation that is being performed is to look for a MalformedURLException. My fix on the local copy of my code (attached) is to attempt to open the URL prior to returning the string to check for a response code of 200. Doing so appears to resolve my issue, though this approach breaks the test in org.cybergarage.upnp.DeviceTest as the testDeviceAbsoluteURL() method need to be able to connect to an actual device.

Hi,

I try to access the Cyber Garage Maven Repository, but it' unavailable now.

Could you please help?

Could you tell me if your Maven repo is temporarily down or if it will not be available again?

How could in this case get the library for android? (jar file)

When some devices is not avaialbe, but it can not reach the the callback method of the DeviceChangeListener that we seted in the ControlPoint.

http://www.cybergarage.org/twiki/bin/view/Main/CyberLinkForJava

timeout when I try to access this site.

Is there a solution to this problem? It has affected the use

in org.cybergarage.http.HTTPHeader.class line 66, "String bigName = name.toUpperCase();" . You should call to upperCase with locale parameter to get right response from getValue function. For example;

"Location".toUpperCase() (in Turkish) = "LOCATİON"

add us locale to solve problem

Just a friendly heads up, a Belkin app for a product called wemo was failing on Android, so I examine the log with logcat and found that it's calling code from this project. I read your license to see it was the 3 clause BSD. I then read the wemo legal text to find that they direct users to visit belkin.com for open source copyright attribution. When I visited their site, I found their open source attribution page and the requested copyright attribute for this project was not listed. They don't offer code for this product, but this likely falls under the redistribution of binary form clause of your license.

Here's the stack trace from their product:

Sorry to bother you if you don't want to enforce the license. I just figured I'd bring it to your attention.

I posted this in the forum, then realized I should open an issue:

I've been seeing the following crash in the field with the CyberLink for Java code:

This is occurring on the renewsubscriber thread. There's another thread for removing expired devices. The renew iterates through the devNodeList, the remove deletes entries from the devNodeList and there's no synchronization between the two. Has anyone else seen this problem? Is it as simple as synchronizing the getDevice() and removeDevice() calls? I'm only seeing this in anonymous crash reports, and it's not common, so reproducing and testing isn't an option.

I am trying to discover my target device from my android application. It worked so far. Now I am trying this on Android Q and my target is not getting discovered.
The same code discovers my target device on lower versions of android (P, O). No errors thrown.
I can see the search packet being broadcasted.

My target device does get listed if I remove the ST: parameter from my search on Anroid Q. I mean ssdp:all lists it. When I add the target parameter to the start() method, it doesn't list my target device. What could be going wrong ?
Any help is appreciated.

Device.java 270 line
String absUrl = locationURLStr + urlString;

need change to

URL locationURL = new URL(locationURLStr);
// 重新拼接url
String absUrl = locationURL.getProtocol() + "://" + locationURL.getHost() + ":" + locationURL.getPort() + urlString;

service.getAction can be work
