How To Set An Alarmmanager For Preselected Days?

I'm creating an alarm widget, and it works, however, I'm currently using it for a single day, I'd like to know how to define it for predefined days, let's say for example I want to

Solution 1:

Defining them at once i don't know if this can be achieved, but i have another scenario to use. Say that you adjusted the Alarm to fire on Monday, Tuesday , Thursday. you will adjust the AlarmManager just for Monday and on Monday it should fire and checks for the next alarm ( which will be on Tuesday ) and so on. Save all you alarms in a database and take them out one be one and in each alarm check for the next one ( if exists )

Solution 2:

You can use the Calendar.DAY_OF_WEEK api like this:

cal1.set(Calendar.DAY_OF_WEEK,2);  //monday
cal2.set(Calendar.DAY_OF_WEEK,4);  //wednesday
cal3.set(Calendar.DAY_OF_WEEK,6);  //friday

and sets 3 alarmMgr like this:

alarmMgr.set(AlarmManager.RTC_WAKEUP, cal1.getTimeInMillis(), AlarmManager.INTERVAL_DAY * 7, testThis(this));  // every monday
alarmMgr.set(AlarmManager.RTC_WAKEUP, cal2.getTimeInMillis(), AlarmManager.INTERVAL_DAY * 7, testThis(this));  // every wednesday
alarmMgr.set(AlarmManager.RTC_WAKEUP, cal3.getTimeInMillis(), AlarmManager.INTERVAL_DAY * 7, testThis(this));  // every friday
