I want to implement a scheduled reminder in a Food/Eating application created in Xamarin Forms (android & ios), that will be displayed at a precise hour on my phone.
Also I want, if it's possible (but I think somehow should be done...), the reminders to be displayed even if the application is not opened. I know that I have some applications installed on my phone, and even if they are closed, the reminders are still displayed.
Could you please help with this topic? I have done some research on the internet but I couldn't found anything that works...
Thank you in advance! Regards!
you should use AlarmManager in android, please refer to alarm-manager-example.
