識別監聽不聽

Question

我創建此服務在後臺監聽，職業服務，但不知道監聽器是否收聽，但只在服務啓動時在Logcat消息中顯示...我已閱讀其他問題在stackoberflow中，但任何運行在我的情況。

public class ServicioVoz extends RecognitionService { 

private SpeechRecognizer sr; 
private VoiceResultsListener vrl; 
public Principal principal; 

@Override 
public void onCreate() { 
    super.onCreate(); 
    Log.i("Dins del servei", "Arrancat"); 
} 

@Override 
public void onDestroy() { 
    super.onDestroy(); 
    Log.i("SimpleVoiceService", "Service stopped"); 
} 

@Override 
protected void onCancel(Callback listener) { 
    sr.cancel(); 
} 

@Override 
protected void onStartListening(Intent recognizerIntent, Callback listener) { 
    Log.e("escoltant", "________________________________"); 
    sr.setRecognitionListener(new VoiceResultsListener(listener)); 
    sr.startListening(recognizerIntent); 
} 

@Override 
protected void onStopListening(Callback listener) { 
    sr.stopListening(); 
    Log.e("Atura d'escoltar", "________________________________"); 
}
