Setting android alarm manager on certain days

Question

I\'m building an app that uses alarm manager. The user sets day and time and there is 7 checkboxs, one for each day of the week and the ones they tick the alarm will go off on t

Answer 1

AlarmManager.setRepeating takes as parameter:

type One of ELAPSED_REALTIME, ELAPSED_REALTIME_WAKEUP}, RTC or RTC_WAKEUP.

Here you will want RTC or RTC_WAKEUP

triggerAtTime Time the alarm should first go off, using the appropriate clock (depending on the alarm type).

Here you give the date/time of the first alarm (I believe this must be UTC time, so be careful)

Calendar calendar = new GregorianCalendar(2011, Calendar.APRIL, 19, 23, 12);
long firstTime = calendar.getTimeInMillis();

interval Interval between subsequent repeats of the alarm.

To repeat every week, you will give as interval the number of milliseconds in a whole week:

long interval = 1000 * 60 * 60 * 24 * 7;

or

long interval = 7 * AlarmManager.INTERVAL_DAY;
