I am currently developing a SharePoint Add-In which has used Add-In internal Lists in which it saved its data. But I am now trying to move the lists out of the Add-In to have more possibilities in administration of these lists such as Event Listeners or Timer Jobs.
I have Custom ContentTypes on one of these Lists and I am also using List Form here to redirect a User to a specific Page within the Add-In with the ListItem-Data.
I am not sure if it is possible to fully move all of the lists out of the Add-In with the Forms and the ContentTypes. The thing is that I am currently redirecting the user to a relative Path of the Add-In if he clicks on a ListItem. But as soon as I move to outside-located Lists I cannot provide a static URL into the Add-In (Which I need for my functionality). (SharePoint always change the URL of the Add-Ins)
Is my problem clear and is here anyone who can help me?
EDIT: I only have the following link besides the "pure" app-url:
But with this URL I cannot provide any parameters to my sharepoint-hosted app/add-in.
