Alarm Manager 를 통해서 예약기능을 구현하려고 합니다.

 

 AlarmManager am = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
   Intent intent;
   PendingIntent sender;
  
   intent = new Intent(Web.this, Alarm_execute.class);
   sender = PendingIntent.getBroadcast(Web.this, 0, intent, 0);
   
   Calendar calendar = Calendar.getInstance();
   calendar.setTimeInMillis(System.currentTimeMillis());
   calendar.add(Calendar.SECOND, 10);
   
   am.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), sender);

현재 이렇게 구현했고

 

 public class Alarm_execute extends BroadcastReceiver{
 @Override
 public void onReceive(Context context, Intent intent) {
  Toast.makeText(context, "알람 연습", Toast.LENGTH_SHORT).show();  
  Log.i("알람 실행",""+1);
  
  //여기서 Web.class 에 있는 Web을 호출해야되는데
  Web web = new Web();
  web.web_connect();
 }
}

 

토스트나 로그찍는건 잘 실행되는데

 

정작 제가 구현하려는 WebView 띄우기는 안되네요

 

혹시 왜 그런지 아시는분 있으시면 알려주심 감사하겠습니다.

 

밑에 로그 첨부합니다.

 

  Web web = new Web();
  web.web_connect();  부분에서 다음과 같이 오류납니다.
