I have a xamarin.forms application that it works with Restful API that implemented inside PCL.
I couldn't access to Firebase service or other PushNots services. Because of that, I developed my own messaging system.
Now I want to have the notification on Android and iOS projects (local notification Maybe). The background service must check every 30 seconds with call a Rest API function From PCL. when the user has a new message I must show a notification. (Even the app had closed)
Please help with background service and access to PCL classes inside the service and local notification (sorry it's a very big question).
thanks in advance.
