Intent intent = new Intent("MY_ALARM_NOTIFICATION");
intent.setClass(myActivity.this,OnAlarmReceive.class);
intent.putExtra("id",id);


PendingIntent pendingIntent = PendingIntent.getBroadcast(
                myActivity.this,Integer.parseInt(id),intent,PendingIntent.FLAG_UPDATE_CURRENT);

Calendar timeCal = Calendar.getInstance();
timeCal.set(Calendar.HOUR_OF_DAY,hour);
timeCal.set(Calendar.MINUTE,minutes);
timeCal.set(Calendar.DAY_OF_MONTH,day);
timeCal.set(Calendar.MONTH,month - 1);
timeCal.set(Calendar.YEAR,year);

Date date = timeCal.getTime();

AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP,timeCal.getTimeInMillis(),pendingIntent);

从设置中删除应用程序时会发生什么？警报仍然存在吗？
