android alarm on specific days

Question

I am making app which uses alarm , which is to be triggered on days specified by the user i.e there are check boxes of days(mon, tue, wed, thu, fri, sat, sun)

I have searched a lot on this question, the only solution i came to know is to trigger different alarms using AlarmManager. its mean if user checks all the 7 boxes, i have to trigger alarm 7 times, and to cancel all 7 pending intents if user cancel one alarm?

my question is , is there any other efficient way to handle this issue??

thanks

I will assume that you want to trigger the alarm at the same time (let's say 12:00 am) no matter what day is it as long as the day is checked. Based on that you can:

• have seven different Boolean sharedPreferences for each day.
• Set the AlarmManager to be triggered daily at 12:00 am.
• When the AlarmManager is triggered, you get the day and check if it is checked:
  • If yes, then do your thing.
  • If no, do nothing.
