WakeLock을 해제하는 동안 강제 종료 하시겠습니까?

Question

버튼을 클릭하면 WakeLock이 켜지고 작동합니다. 하지만 다시 클릭하면 WakeLock을 사용 중지한다고 가정하지만 대신 응용 프로그램이 중지됩니다! 어떤 도움도 감사 하겠고 이미지가 바뀌기 때문에 그 부분이 잘 작동하기 때문에 그 부분을 알지 못합니다! :) Heres는 내 코드 :

PowerManager.WakeLock wl; //This is before my oncreate 
int stayAwake = 0; //This is before my oncreate 

    ((Button) findViewById(R.id.sleepLock)).setOnClickListener(new View.OnClickListener() { 

    @Override 
    public void onClick(View v) { 
    PowerManager pm = (PowerManager) getSystemService (Context.POWER_SERVICE); 
    wl = pm.newWakeLock (PowerManager.FULL_WAKE_LOCK, "My Tag"); 
     if (stayAwake == 0) { 
     ((Button) findViewById(R.id.sleepLock)).setBackgroundResource(R.drawable.awake); 
     stayAwake = 1; 
     wl.acquire(); 
     }else { 
      ((Button) findViewById(R.id.sleepLock)).setBackgroundResource(R.drawable.sleep); 
      stayAwake = 0; 
      wl.release(); 
     } 

     // TODO Auto-generated method stub 

    } 
});

변경에 ClickListener 다시 버튼을 다시 초기화하고 설정하지 않는 한 어떤 기준을 가지고 있지 않는 버튼을 잠금 해제하는 동안 코드는

Button btn=(Button) findViewById(R.id.sleepLock); 
PowerManager.WakeLock wl; //This is before my oncreate 
int stayAwake = 0; //This is before my oncreate 

btn.setOnClickListener(new View.OnClickListener() { 

    @Override 
    public void onClick(View v) { 
     PowerManager pm = (PowerManager) getSystemService (Context.POWER_SERVICE); 
     wl = pm.newWakeLock (PowerManager.FULL_WAKE_LOCK, "My Tag"); 
     if (stayAwake == 0) { 
      btn.setBackgroundResource(R.drawable.awake); 
      stayAwake = 1; 
      wl.acquire(); 
     } else { 
      btn.setBackgroundResource(R.drawable.sleep); 
      stayAwake = 0; 
      wl.release(); 
     } 
    } 
}); 

이제 코드는 잘
