Android-Нестабильный, медленный, ненадежный PING

Question

У меня есть приложение для Android, где есть список серверов и код для их ping. Но, когда я пингую один из них, он всегда работает, но для того, чтобы пинговать больше из них подряд или более, чем один (с несколькими секундными сделками), приложение очень неустойчиво, отстает или что-то еще (иногда logcat говорит, что некоторые (600 +) кадры пропущены, слишком много работы на главной теме (хореограф: пропущено 4230 кадров! Приложение может делать слишком много работы над своей основной нитью.)). Приложение отлично работало, когда у меня было всего 1 сервер для пинга, я попытался использовать метод, размещенный в коде здесь, с помощью ping их всех одной кнопкой или ping только 1 половина из них и т. Д. Что не так? (Должно ли быть слишком много onClickListeners? Я думаю, что не потому, что, когда у меня была только одна кнопка для ping, все они делали то же самое). Приложение после щелчка на том, что textView не сбой, но отставание в течение 5 + сек.

Благодарим за решение.

Каждый раз, когда вы нажимаете кнопку, основной поток пользовательского интерфейса запускает процесс, а затем ждет его завершения, в результате чего поток пользовательского интерфейса приостанавливается. Эта пауза - это то, что заставляет Android сообщать о предупреждениях «слишком много работы с основным потоком» и вашем приложении «отставать».

Вам необходимо изменить методы ping(), чтобы они запускались в отдельных потоках и не вызывали зависание потока пользовательского интерфейса.

Что-то вроде этого:

public class Second_Fragment extends Fragment { 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
     myView2 = inflater.inflate(R.layout.second_layout, container, false); 
     //click button 
     TextView clickFirstButton = (TextView) myView2.findViewById(R.id.uae); 
     clickFirstButton.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       // launch the ping process in a separate thread 
       new Thread(pingUAE).start(); 
      } 
     }); 
     return myView2; 
    } 

    void setPingResult(int id, long pingtime) { 
      TextView textView = (TextView)myView2.findViewById(id); 
      if (pingtime >= 0) { 
       textView.setText("server on, ping is: " + pingtime + "ms"); 
      } 
      else { 
       textView.setText("server off "); 
      } 
    } 


    public Runnable pingUAE = new Runnable() { 
     @Override 
     public void run() { 
      // initialise time to -1 
      uae = -1; 
      Runtime runtime = Runtime.getRuntime(); 
      try { 
       long a = System.currentTimeMillis() % 1000; 
       Process ipProcess = runtime.exec("/system/bin/ping -c 1 8.8.8.8"); 
       int  exitValue = ipProcess.waitFor(); 
       uae = System.currentTimeMillis() % 1000 - a; 
      } catch (IOException e)   { e.printStackTrace(); } 
      catch (InterruptedException e) { e.printStackTrace(); } 

      // update the ping result - we need to call this on the UI thread 
      // because it updates UI elements (TextView) 
      getActivity().runOnUIThread(new Runnable() { 
       @Override 
       public void run() { 
        setPingResult(R.id.uae, uae); 
       } 
      }); 

     } 
    } 

}
