機器人自動檢測語言

Question

我試過this庫，在堆棧溢出的職位之一建議，

我添加的lib的jar到我的構建路徑，但我不能初始化DetectorFactory類與語言的配置文件。

這是類處理的檢測，如在其樣品中的一個提示：

class LanguageDetector { 
    public void init(String profileDirectory) throws LangDetectException { 
     DetectorFactory.loadProfile(profileDirectory); 
    } 
    public String detect(String text) throws LangDetectException { 
     Detector detector = DetectorFactory.create(); 
     detector.append(text); 
     return detector.detect(); 
    } 
    public ArrayList<Language> detectLangs(String text) throws LangDetectException { 
     Detector detector = DetectorFactory.create(); 
     detector.append(text); 
     return detector.getProbabilities(); 
    } 
} 

簡檔被存儲在myProject的/簡檔的所有語言。 試圖將類實例崩潰我的應用程序沒有任何有用的消息logcat的

調用類（）：

@Override 
    public void onActivityCreated(Bundle savedInstanceState) { 
     super.onActivityCreated(savedInstanceState); 
     context = this.getActivity().getApplicationContext(); 
/*  LanguageDetector detector = null; 
     try { 
      detector.init("/waggle/profiles"); 
     } catch (LangDetectException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     }*/ 
     new GetDataTask().execute(context); 

    }

變化LanguageDetector方法靜態：

class LanguageDetector { 
    public static void init(String profileDirectory) throws LangDetectException { 
     DetectorFactory.loadProfile(profileDirectory); 
    } 
    public static String detect(String text) throws LangDetectException { 
     Detector detector = DetectorFactory.create(); 
     detector.append(text); 
     return detector.detect(); 
    } 
    public static ArrayList<Language> detectLangs(String text) throws LangDetectException { 
     Detector detector = DetectorFactory.create(); 
     detector.append(text); 
     return detector.getProbabilities(); 
    } 
} 

與應用，如下：

try { 
    LanguageDetector.init("/waggle/profiles"); // <-- Are you sure the profiles are at this location??? 
} catch (LangDetectException e) { 
    // TODO Auto-generated catch block 
    e.printStackTrace(); 
} 

String detectedLanguage = null; 
try { 
    detectedLanguage = LanguageDetector.detect("Dies ist ein Beispiel in Deutsch."); 
} catch (LangDetectException e) { 
    // TODO Auto-generated catch block 
    e.printStackTrace(); 
} 

if (detectedLanguage != null) { 
    // Implement your logic here 
}
