我想写使用Cyber​​Garage讯连科技的JavaAPI UPnP控制点应用程序为Android。为了测试API我实现了一个非常简单的应用程序。在本申请中的UPnP控制点主动搜索任何的UPnP根设备，侦听响应和设备通知，并打印设备，这是在网络上可用的列表。

I want to write a UPnP control point application for Android using the CyberGarage "CyberLink for Java" API. To test the API I implemented a very simple application. In this application a UPnP control point actively searches for any UPnP root devices, listens for responses and device notifications, and prints a list of the devices, which are available on the network.

在应用程序运行在Android手机上，但是没有我的网络上的UPnP设备的发现。我想这两个不同的Andr​​oid手机。要检查，如果这是一个Android的具体问题，我实现相同的功能作为一个Java控制台应用程序。有趣的是Java控制台应用程序的工作原理精绝，总是显示所有的UPnP设备我的网络上！

The app runs on an Android phone, but none of the UPnP devices on my network are found. I tried this on two different Android phones. To check out if this is an Android specific problem, I implemented the same functionality as a Java console application. Interestingly enough the Java console application works absolutely fine and always shows all of the UPnP devices on my network!

那么，为什么在Android这个不工作？请注意，在Android应用程序，我不得不实施使用AsyncTask的一个单独的线程在网络特定的功能。否则我得到的错误，因为我不应该在UI线程上运行此。但是，这不应该成为问题，对吗？

So why does this not work on Android? Note, in the Android app I had to implement the network specific functionality on a seperate thread using AsyncTask. Otherwise I get errors, because I am not supposed to run this on the UI thread. But this should not be the problem, am I right?

下面的两个应用程序的源$ C ​​$ C。

Below the source code of the two applications.

Android应用程序：

Android application:

MainActivity.java

MainActivity.java

package com.example.controller_v1;

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        UPnP.setEnable(UPnP.USE_ONLY_IPV4_ADDR);
        new StartControlPointTask().execute();
    }

    private class StartControlPointTask extends AsyncTask {
        public static final String TAG = "StartControlPointTask";

        @Override

            } catch (InterruptedException e) {
                e.printStackTrace();
            }
            DeviceList rootDevices = controlPoint.getDeviceList();
            int numDevices = rootDevices.size();
            if (numDevices > 0) {
                for (int i = 0; i < numDevices; i++) {
                    Log.i(TAG, "device " + i + ": " + rootDevices.getDevice(i).getFriendlyName());
                }
            } else {
                Log.i(TAG, "no root devices found");//
            }
            return null;
        }   
    }
}

        final String TAG = "deviceSearchResponseReceived";
        Log.i(TAG, "executed");

}

AndroidManifest.xml中

Java控制台应用程序：

Java console application:

public class Main {
    public Main() {
        UPnP.setEnable(UPnP.USE_ONLY_IPV4_ADDR);
        MyControlPoint controlPoint = new MyControlPoint();
        controlPoint.start();
//      controlPoint.search();

        try {
            Thread.sleep(5000); // wait for devices to be found
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        DeviceList rootDevices = controlPoint.getDeviceList();
        int numDevices = rootDevices.size();
        if (numDevices > 0) {
            for (int i = 0; i < numDevices; i++) {
                System.out.println("found device " + i + ": " + rootDevices.getDevice(i).getFriendlyName());
            }   
        } else {
            System.out.println("no root devices found");
        }
    }

    public static void main(String[] args) {
        new Main();
    }
}

MyControlPoint.java

MyControlPoint.java

import org.cybergarage.upnp.ControlPoint;
import org.cybergarage.upnp.device.NotifyListener;
import org.cybergarage.upnp.device.SearchResponseListener;
import org.cybergarage.upnp.ssdp.SSDPPacket;

public class MyControlPoint extends ControlPoint implements /*DeviceChangeListener,*/ NotifyListener, SearchResponseListener {
    public MyControlPoint() {
        addNotifyListener(this);
        addSearchResponseListener(this);
    }

    @Override
    public void deviceNotifyReceived(SSDPPacket packet) { // NotifyListener
        System.out.println("deviceNotifyReceived");
    }

    @Override
    public void deviceSearchResponseReceived(SSDPPacket packet) { // SearchResponseListener
        System.out.println("deviceSearchReceived");
    }
}

我没有任何想法，为什么Java控制台应用程序的工作原理及Android应用程序没有。我没有得到的文件任何回答。任何人可以帮助我吗？

I don't have any idea, why the java console application works and the android application doesn't. I don't get any answer from the documentation. Can anybody help me?

推荐答案

在我的情况下，它显示的是所有的设备，可能是因为我用电话核对，而仿真器。

In my case it is displaying all the devices, may be because I'm checking with Phone rather emulator.
