在亞行開始intentservice失敗

Question

當我嘗試當我開始提供正常的服務OVRE ADB，everithing正常工作重新開始，亞行的IntentService我得到壽以下錯誤

E/AndroidRuntime(2418): java.lang.RuntimeException: Unable to instantiate service 
com.myCompany.MyPackage.Service: java.lang.InstantiationException: 
com.myCompany.MyPackage.Service 

。

無法通過adb啓動intentservice的原因是什麼？

public class NCService extends IntentService { 

public NCService(String name) { 
    super(name); 
    // TODO Auto-generated constructor stub 
} 

NetworkStateReceiver nsr; 

@Override 
public int onStartCommand(Intent intent, int flags, int startId) { 
    // TODO Auto-generated method stub 
    Toast.makeText(getBaseContext(), "onStartCommand", 0).show(); 
    nsr = new NetworkStateReceiver(); 

    return START_STICKY; 
} 

@Override 
public void onCreate() { 
    // TODO Auto-generated method stub 
    Toast.makeText(getBaseContext(), "onCreate", 0).show(); 
    super.onCreate(); 
} 

@Override 
public void onDestroy() { 
    // TODO Auto-generated method stub 
    Toast.makeText(getBaseContext(), "onDestroy", 0).show(); 
    super.onDestroy(); 
} 

@Override 
public IBinder onBind(Intent intent) { 
    // TODO Auto-generated method stub 
    return null; 
} 

@Override 
protected void onHandleIntent(Intent intent) { 
    // TODO Auto-generated method stub 

} 

}

您的服務需要一個默認的無參數的構造函數，否則Android不知道什麼參數傳遞的名稱參數：

public NCService() { 
    super("MyNCService"); 
}
