내 코드 :

public class MainActivity extends Activity implements View.OnClickListener { 
    private TimerThread timerThread; 
    private boolean timerHasStarted = false; 
    private Button button; 
    private TextView text; 
    private final long startTime = 1000; 
    private final long interval = 1; 
    private Handler handler; 
    private Runnable r; 
    private MediaPlayer mp; 
    private TimerTask task; 
    private Timer timer; 
    private long delay; 
    private Boolean play = true; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 

     setContentView(R.layout.main); 
     getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
       WindowManager.LayoutParams.FLAG_FULLSCREEN); 

     button = (Button) this.findViewById(R.id.button); 
     button.setOnClickListener(this); 

     text = (TextView) this.findViewById(R.id.timer); 
     mp = MediaPlayer.create(this, R.raw.cpush); 
     //mp.start(); 
     delay = 1000; 

     timer = new Timer(); 
     timerThread = new TimerThread(); 
     timer.scheduleAtFixedRate(task, 0, 10); 
    } 

    public long nextLong(Random rng, long n) { 
     long bits, val; 
     do { 
      bits = (rng.nextLong() << 1) >>> 1; 
      val = bits % n; 
     } while (bits - val + (n - 1) < 0L); 
     return val; 
    } 

    @Override 
    public void onClick(View v) { 
     button.setBackgroundResource(R.drawable.finish);

     else{ 
      play = true; 
      /* RESTART TimerTask Hear*/

    public class TimerThread extends TimerTask { 
     @Override 
     public void run() { 
      Random rand = new Random(); 
      final long value = nextLong(rand, 9999999999999999L); 

      runOnUiThread(new Runnable() { 
       @Override
