我正在开发一个使用 Cling 执行 UPNP 扫描的 Android 应用程序。它记录它接收数据包，但随后它因 Jetty 的 NoClassDefFound 异常而崩溃。
下面是我用来执行扫描的代码
ServiceConnection serviceConnection = new ServiceConnection()
{
@Override
public void onServiceConnected(ComponentName name, IBinder service)
{
upnpService = (AndroidUpnpService)service;
upnpService.getRegistry().addListener(listener);
upnpService.getControlPoint().search();
}
@Override
public void onServiceDisconnected(ComponentName name)
{
upnpService = null;
}
};
public HueBridgeSearch(Context context, Activity activity)
{
this.context = context;
this.activity = activity;
}
public void startBridgeSearch()
{
// Fix the logging integration between java.util.logging and Android internal logging
org.seamless.util.logging.LoggingUtil.resetRootHandler(
new FixedAndroidLogHandler()
);
Logger.getLogger("org.fourthline.cling").setLevel(Level.ALL);
listener = new RegistryListener()
{
@Override
public void remoteDeviceDiscoveryStarted(Registry registry, RemoteDevice remoteDevice)
{
Log.d(TAG, "Remote Device Discovery Started: " + remoteDevice.getDisplayString());
Toast.makeText(context, "GOT SOMETHING", Toast.LENGTH_SHORT).show();
}
@Override
public void remoteDeviceDiscoveryFailed(Registry registry, RemoteDevice remoteDevice, Exception e)
{
Log.d(TAG, "Remote device discovery failed: " + remoteDevice.getDisplayString());
Log.d(TAG, "Remote device discovery failed: " + e.toString());
Toast.makeText(context, "GOT SOMETHING", Toast.LENGTH_SHORT).show();
}
@Override
public void remoteDeviceAdded(Registry registry, RemoteDevice remoteDevice)
{
Log.d(TAG, "Added Found Device: " + remoteDevice.getDisplayString());
Toast.makeText(context, "GOT SOMETHING", Toast.LENGTH_SHORT).show();
}
@Override
public void remoteDeviceUpdated(Registry registry, RemoteDevice remoteDevice)
{
Log.d(TAG, "Updated Found Device: " + remoteDevice.getDisplayString());
Toast.makeText(context, "GOT SOMETHING", Toast.LENGTH_SHORT).show();
}
@Override
public void remoteDeviceRemoved(Registry registry, RemoteDevice remoteDevice)
{
Toast.makeText(context, "GOT SOMETHING", Toast.LENGTH_SHORT).show();
}
@Override
public void localDeviceAdded(Registry registry, LocalDevice localDevice)
{
Log.d(TAG, "Local Added Found Device: " + localDevice.getDisplayString());
Toast.makeText(context, "GOT SOMETHING", Toast.LENGTH_SHORT).show();
}
@Override
public void localDeviceRemoved(Registry registry, LocalDevice localDevice)
{
Toast.makeText(context, "GOT SOMETHING", Toast.LENGTH_SHORT).show();
}
@Override
public void beforeShutdown(Registry registry)
{
Toast.makeText(context, "GOT SOMETHING", Toast.LENGTH_SHORT).show();
}
@Override
public void afterShutdown()
{
Toast.makeText(context, "GOT SOMETHING", Toast.LENGTH_SHORT).show();
}
};
Intent intent = new Intent(activity, AndroidUpnpServiceImpl.class);
//intent.setClassName("org.fourthline.cling.android", "org.fourthline.cling.android.AndroidUpnpServiceImpl");
boolean success = context.bindService(intent,
serviceConnection, Context.BIND_AUTO_CREATE);
}
下面是我的 gradle 构建文件依赖项
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
compile files('libs/cling-core-2.1.0.jar')
compile files('libs/seamless-util-1.1.1.jar')
compile 'com.android.support:appcompat-v7:23.3.0'
compile files('libs/jetty-server-9.2.15.v20160210.jar')
compile files('libs/jetty-servlet-9.2.15.v20160210.jar')
compile files('libs/jetty-servlets-9.2.15.v20160210.jar')
compile files('libs/seamless-http-1.1.1.jar')
}
它编译得很好，但是在运行时我得到了以下异常
