I have any app that uses a background service. And sometimes the service will encounter an error. When this happens it is VERY important that I interrupt what the user is doing and display the error to the user and they have to acknowledge the error before they can resume their activity in the app.
I can't use Toastmessage because that disappears after a few seconds.
So, what is the recommended way to display a message (such as a msgbox) to the user no matter what activity they are currently using?
So, would I then do a CallSubDelay from the service to display this "special" activity that is dedicated to just displaying these error messages?
If so, then will this "special" activity be display relatively immediately if the user is currently using the app (app in foreground) but the user is displaying a different activity?
