枚举<url> configs.hasMoreElements（）给出false

Question

我正在Android中开发一个基于语音的应用程序并面临一些问题，请参阅下面的代码，

Java文件1 file = .wav文件

public static AudioInputStream getAudioInputStream(File file) throws UnsupportedAudioFileException, IOException {
    return getAudioInputStreamImpl(file);
}
private static AudioInputStream getAudioInputStreamImpl(Object source) throws UnsupportedAudioFileException, IOException {
    GetAudioInputStreamAudioFileReaderAction action = new GetAudioInputStreamAudioFileReaderAction(source);
    doAudioFileReaderIteration(action);
    AudioInputStream audioInputStream = action.getAudioInputStream();

    if (audioInputStream != null) {
        return audioInputStream;
    }
    throw new UnsupportedAudioFileException("format not supported");
}
private static void doAudioFileReaderIteration(AudioFileReaderAction action) throws IOException {
    Iterator audioFileReaders = TAudioConfig.getAudioFileReaders();
    boolean bCompleted = false;

    while (audioFileReaders.hasNext() && !bCompleted) {
        AudioFileReader audioFileReader = (AudioFileReader) audioFileReaders.next();
        bCompleted = action.handleAudioFileReader(audioFileReader);
    }
}

Java文件2（TAudioConfig）

public static synchronized Iterator<AudioFileReader> getAudioFileReaders() {
    Iterator<AudioFileReader> it;
    synchronized (TAudioConfig.class) {
        it = getAudioFileReadersImpl().iterator();
    }
    return it;
}
private static synchronized Set<AudioFileReader> getAudioFileReadersImpl() {
    Set<AudioFileReader> set;
    synchronized (TAudioConfig.class) {
        if (sm_audioFileReaders == null) {
            sm_audioFileReaders = new ArraySet();
            registerAudioFileReaders();
        }
        set = sm_audioFileReaders;
    }
    return set;
}
private static void registerAudioFileReaders() {
    TInit.registerClasses(AudioFileReader.class, new C00001());
}

Java File 3（TInit）

public static void registerClasses(Class providerClass, ProviderRegistrationAction action) {


    Iterator providers = Service.providers(providerClass);
    if (providers != null) {
        while (providers.hasNext()) {
            try {
                action.register(providers.next());
            } catch (Throwable e) {

            }
        }
    }
}

Java File 4（服务）

public static Iterator<?> providers(Class<?> cls) {

    String strFullName = "com/example/voiceautomator/AudioFileReader.class";

    Iterator<?> iterator = createInstancesList(strFullName).iterator();
    return iterator;
}
private static List<Object> createInstancesList(String strFullName) {   
    List<Object> providers = new ArrayList<Object>();
    Iterator<?> classNames = createClassNames(strFullName);
    if (classNames != null) {
        while (classNames.hasNext()) {
            String strClassName = (String) classNames.next();
            try {
                Class<?> cls = Class.forName(strClassName, REVERSE_ORDER, ClassLoader.getSystemClassLoader());

                providers.add(0, cls.newInstance());
            } catch (Throwable e) {

            }
        }
    }
    return providers;
}
private static Iterator<String> createClassNames(String strFullName) {       
    Set<String> providers = new ArraySet<String>();
    Enumeration<?> configs = null;        
    try {
                    configs =  Service.class.getClassLoader().getSystemResources(strFullName);
    } catch (Throwable e) {

    }
    if (configs != null) {
        while (configs.hasMoreElements()) {
            URL configFileUrl = (URL) configs.nextElement();

            InputStream input = null;
            try {
                input = configFileUrl.openStream();
            } catch (Throwable e2) {


            }
            if (input != null) {
                BufferedReader reader = new BufferedReader(new InputStreamReader(input));
                try {
                    for (String strLine = reader.readLine(); strLine != null; strLine = reader.readLine()) {
                        strLine = strLine.trim();
                        int nPos = strLine.indexOf(35);
                        if (nPos >= 0) {
                            strLine = strLine.substring(0, nPos);
                        }
                        if (strLine.length() > 0) {
                            providers.add(strLine);
                        }
                    }
                } catch (Throwable e22) {

                }
            }
        }
    }
    Iterator<String> iterator = providers.iterator();

    return iterator;
}

getClassLoader（）。Java File 4（Service）中的getSystemResources给了我TwoEnumerationsInOne，configs.hasMoreElements（）给出了false，因此无法进入while循环。

AudioFileReader.java包含在包

中

请指导我解决此问题？

请不要忘记我在Android项目中处理此代码
