我正在尝试从android device.my java方法调用一些java方法我通过axis2 web服务访问。
这是我的完整Java类，我已经编写了两个方法来调用Adnroid Device。并且不知何故它只是调用get_wav_byte（）方法成功但是对于另一个方法它给我的错误如下
at java.lang.Thread.run（Thread.java:662） 引起：java.lang.NoClassDefFoundError：edu / cmu / sphinx / util / props / ConfigurationManager
我的外部jar库中的类是我在recogn_wave（String wavePath）方法中使用的。 我还检查了edu / cmu / sphinx / util / props / ConfigurationManager在jar文件中可用，包括仍然给我错误。我给你我的java和android的完整代码如下
JAVA方法：
package edu.cmu.sphinx.demo.transcriber;
import edu.cmu.sphinx.frontend.util.AudioFileDataSource;
import edu.cmu.sphinx.recognizer.Recognizer;
import edu.cmu.sphinx.result.Result;
//import edu.cmu.sphinx.util.props.ConfigurationManager;

import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.net.MalformedURLException;
import java.net.URL;
import javax.sound.sampled.UnsupportedAudioFileException;
/** A simple example that shows how to transcribe a continuous audio file that has multiple utterances in it. */
public class Transcriber {
// private static final String PATH = "file:///D:\\Sound\\";
@SuppressWarnings("null")
public static String recognize_wave(String wavePath) throws MalformedURLException{
String resultText="";
URL audioURL;
audioURL = new URL(wavePath);
URL configURL = Transcriber.class.getResource("config.xml");
ConfigurationManager cm = new ConfigurationManager(configURL);
Recognizer recognizer = (Recognizer) cm.lookup("recognizer");
/* allocate the resource necessary for the recognizer */
recognizer.allocate();
// configure the audio input for the recognizer
AudioFileDataSource dataSource = (AudioFileDataSource) cm.lookup("audioFileDataSource");
dataSource.setAudioFile(audioURL, null);
// Loop until last utterance in the audio file has been decoded, in which case the recognizer will return null.
Result result;
while ((result = recognizer.recognize())!= null) {
resultText = result.getBestResultNoFiller();
System.out.println(resultText);
}
return resultText;
}
public String get_wav_byte(byte[] wavbite,String path) throws IOException
{
String result1="null";
//return result1;
final String PATH = "file:///D:\\Sound\\";
//System.out.println(bhavik1111);
try
{
File dstFile = new File(path);
FileOutputStream out = new FileOutputStream(dstFile);
out.write(wavbite, 0, wavbite.length);
out.close();
}
catch (IOException e)
{
System.out.println("IOException : " + e);
}
try {
result1=recognize_wave(path);
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return result1;
}
}

我能理解的是一些它不能正常工作因为我在公共静态字符串中使用外部jar文件string_wave（String wavePath）方法。
我有很多搜索，但仍然没有良好的指导......
希望你能帮助我..提前感谢..
答案 0 :(得分：0)
检查以确保外部jar文件包含在构建路径中以及位于libs文件夹中。如果您没有libs文件夹，则可以在项目的根目录中创建一个。然后将jar文件复制并粘贴到此位置。然后右键单击Eclipse中的jar文件，转到Build Path，然后单击Add To Build Path。如果您的libs文件夹中有jar文件，则不会出现任何编译器错误。但那只是编译时间。如果jar不在构建路径中，它将在运行时失败。
