title: Pause the timer and then continue it
body: <p>Refer to the code that @Yuri posted from here. <a href="https://stackoverflow.com/questions/11489988/how-to-stop-a-timer-after-certain-number-of-times">How to stop a timer after certain number of times</a>  . If I wanted to stop it because of some condition and then restart it again. How would I go about doing it?</p>
  
  <pre><code>    private final static int DELAY = 10000;
      private final Handler handler = new Handler();
      private final Timer timer = new Timer();
      private final TimerTask task = new TimerTask() {
          private int counter = 0;
          public void run() {
              handler.post(new Runnable() {
                  public void run() {
                      Toast.makeText(MainActivity.this, "test", Toast.LENGTH_SHORT).show();
                  }
              });
              if(++counter == 4) {
                  timer.cancel();
              }
  
      //do some stuff in my app
     //restart the timer again
  
          }
      };

          super.onCreate(savedInstanceState);

          timer.schedule(task, DELAY, DELAY);

  <p>Here's what I've tried , but it keeps crashing on me.</p>
  
  <pre><code>    final int DELAY = 10000;
          Timer timer;
          MyTask task;
          startManager Scanner;
          Handler handler;
  
  
  
          public class MyTask extends TimerTask {
  
              @Override
              public void run() {
                  handler.post(new Runnable() {
                      public void run() {
                          //do Stuff here
                          }
          });
      }
          public class startManager {
  
              public startManager() {
                  handler = new Handler();
                  timer = new Timer();
              }
  
              public void start() {
  
                  timer.schedule(task, 0, DELAY);
              }
  
              public void cancel() {
  
                  timer.cancel();
                  timer.purge();
  
              }
          }
  
      }
  
   @Override
          public void onCreate(Bundle savedInstanceState) {
              super.onCreate(savedInstanceState);
