I am practicing and learning Xamarin and for this I have started to make an application of an agenda. To remind the user of the tasks that are scheduled, I use a method in a second thread that checks the dates of the tasks every 4 minutes and depends on the date to send a notification or not. Well, the issue is that leaving the application in the background seems to stop checking the tasks since it does not launch notifications. I do not know if there is any method or option to prevent android from loading the application that is in backgound.
Thank you.
