Advice, Please - Notifications

[AlanScottAgain 1]

Hi,

This is my scenario....
I have an exercise app that will be able to set reminders to do the exercise daily up to 2 times a day.
I need to create a notification that will remind the user to the exercise. Taping the reminder should open the app - to record the exercise has been done.

The reminders will need to be active after a reboot and work on both Android and iPhone.

After reading lots of articles.. I'm completely  confused and would like some pointers, Please.

Thanks
Alan

PS it would be good if I could send a notification if the exercise has not been done/logged on the app.

On Android, for notifications to still work after a reboot, you would need to persist them in some way, and recreate them, *and* have the app start at boot. I have an example of how to have an app that starts at boot, here:

This is a demo from Embarcadero of how to create/send notifications:

As discussed above, if you want to recreate the notification at device start you would also need to persist them somehow, e.g. using a database, or perhaps as JSON, read the data and recreate the notifications when the app starts. You would need to handle when a notification is received, so that you remove it from the persisted notifications.

 

On iOS, as far as I know you are out of luck regarding recreating notifications at device start - there does not appear to be anyway for an app to handle this, without the user starting the app.

Thank you David,

Do I need to create a service app to read the data and recreate the notification after start up? Would that work on iOS?
