请检查我没有收到通知。如果用户提供日期和时间，请在特定日期和时间收到通知。

Answer 1

private void setAlarm(Date targetCal, boolean isEditMode) {

        Intent myIntent = new Intent(AddEventActivity.this, MyReceiver.class);
        myIntent.putExtra("MODE", isEditMode);
        myIntent.putExtra("time", targetCal.getTime());
        myIntent.putExtra("title", mTitle);
        pendingIntent = PendingIntent.getBroadcast(AddEventActivity.this, 0, myIntent, 0);

        AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
        alarmManager.set(AlarmManager.RTC, targetCal.getTime(), pendingIntent);
    }
