如何使用RTC唤醒和警报意图

Question

I'm working on a project, my goal is to configurate a cell phone. I have to related the sounds of the phone with a calendar .

The user can choose the day, the beginning hour and the ending hour and, the configuration parameters of the sound. An example, every monday, the application has to put the phone in silence mode, between 8 am and 4 pm .

I already have all the parameters, all I have to do now, is to apply them. To do so, I think the use of RTC Wake Up is the best.

Here's the code that i'm working on :

TimePicker hourBeginning = (TimePicker)findViewById(R.id.hourBeginningTimePicker);
TimePicker hourEnding = (TimePicker)findViewById(R.id.hourEndingTimePicker);
SeekBar volumePhone = (SeekBar)findViewById(R.id.volumePhoneOptionSeekBar);
SeekBar volumeAlarm = (SeekBar)findViewById(R.id.volumeAlarmOptionSeekBar);
SeekBar volumeApplication = (SeekBar)findViewById(R.id.volumeApplicationOptionSeekBar);

Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.set(Calendar.HOUR_OF_DAY, heureBeginning.getCurrentHour());
calendar.set(Calendar.MINUTE, heureEnding.getCurrentMinute());


// With setInexactRepeating(), you have to use one of the AlarmManager interval
// constants--in this case, AlarmManager.INTERVAL_DAY.
alarmMgr.setInexactRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),
                AlarmManager.INTERVAL_DAY, alarmIntent);

I don't understand how this works, and how it suppose to solve my problem :

// With setInexactRepeating(), you have to use one of the AlarmManager interval
// constants--in this case, AlarmManager.INTERVAL_DAY.
alarmMgr.setInexactRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),
                AlarmManager.INTERVAL_DAY, alarmIntent);

If you think, there's a better solution, or know how to use correctly RTC Wake Up to solve my problem, help would be appreciated.

Thanks.

Use alarm manager to trigger the alarm at a specific defined time.

AlarmManager alarmMgr = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
    Intent intent = new Intent(getApplicationContext(),
            xyz.class);

    PendingIntent alarmIntent = PendingIntent
            .getService(getApplicationContext(), 0, intent,
                    PendingIntent.FLAG_ONE_SHOT);

    Calendar calendar = Calendar.getInstance();
    calendar.set(Calendar.HOUR_OF_DAY, 14);
    calendar.set(Calendar.MINUTE, 00);
    calendar.set(Calendar.SECOND, 00);

    alarmMgr.setInexactRepeating(AlarmManager.RTC_WAKEUP,
            calendar.getTimeInMillis(), 1000 * 60 * 60 * 24, alarmIntent);
