报警应用程序，我有一个用于保存警报的菜单选项，但当我尝试单击保存菜单选项时，我的应用程序崩溃

Question

我正在尝试制作闹钟应用程序，我在菜单中提供了一个保存选项以保存新警报，每次我尝试保存应用程序崩溃时都是如此。 我把我的日志可以帮助我理解我的应用程序中的问题？ 我的代码很少

public boolean onOptionsItemSelected(MenuItem item) {

switch (item.getItemId()) {
/*checksonu case android.R.id.home: {
    finish();
    break;
} */
case R.id.action_save_alarm_details: {
    updateModelFromLayout();

    AlarmManagerHelper.cancelAlarms(this);

    if (alarmDetails.id < 0) {
        dbHelper.createAlarm(alarmDetails);
    } else {
        dbHelper.updateAlarm(alarmDetails);
    }

    AlarmManagerHelper.setAlarms(this);

    setResult(RESULT_OK);
    finish();
}
}

return super.onOptionsItemSelected(item);
}

public static void setAlarms(Context context) {
cancelAlarms(context);

AlarmDBHelper dbHelper = new AlarmDBHelper(context);

List<AlarmModel> alarms = dbHelper.getAlarms();

for (AlarmModel alarm : alarms) {
if (alarm.isEnabled) {

    PendingIntent pIntent = createPendingIntent(context, alarm);

    Calendar calendar = Calendar.getInstance();
    calendar.set(Calendar.HOUR_OF_DAY, alarm.timeHour);
    calendar.set(Calendar.MINUTE, alarm.timeMinute);
    calendar.set(Calendar.SECOND, 00);

    //Find next time to set
    final int nowDay = Calendar.getInstance().get(Calendar.DAY_OF_WEEK);
    final int nowHour = Calendar.getInstance().get(Calendar.HOUR_OF_DAY);
    final int nowMinute = Calendar.getInstance().get(Calendar.MINUTE);
    boolean alarmSet = false;

    //First check if it's later in the week
    for (int dayOfWeek = Calendar.SUNDAY; dayOfWeek <= Calendar.SATURDAY; ++dayOfWeek) {
        if (alarm.getRepeatingDay(dayOfWeek - 1) && dayOfWeek >= nowDay &&
                !(dayOfWeek == nowDay && alarm.timeHour < nowHour) &&
                !(dayOfWeek == nowDay && alarm.timeHour == nowHour && alarm.timeMinute <= nowMinute)) {
            calendar.set(Calendar.DAY_OF_WEEK, dayOfWeek);

                calendar.set(Calendar.DAY_OF_WEEK, dayOfWeek);
                calendar.add(Calendar.WEEK_OF_YEAR, 1);
