I am building a reminder application where the user enters an event into an SQLite DB. The main screen lists the title of each reminder and clicking an item shows the details of it. All of this works fine.

Now I want to allow the user to set up notifications for each item, being given an option to set a reminder for 15 mins, 30 mins, or 1hr before the event is scheduled.

I have no clue how to go about this and can’t find any good tutorial on it. Can anyone give me some idea as to how I might implement this?

Thanks!

    You’ll use the AlarmManager to set the action to be triggered on the specific date/time. (there’re A LOT of tutorials on how to use the AlarmManager)

    The alarm manager event always triggers a PendingIntent. From this intent you can either make a broadcast or start a service. (you’ll have to create a broadcast receiver or a service)

    Then on the broadcast receiver or service you build up and show the notification.

    I suggest the broadcast receiver route, it’s cleaner and more seamless.
    you might also to have a broadcast receiver for onBoot events to re-schedule the events on the alarm manager case the user reboots the device.
