I need help creating a Tasker profile that will open Aldiko Sync ONLY after I have ended the main Aldiko Premium app.
So with this profile, Aldiko Sync automatically launches and does its thing immediately after I close Aldiko Premium reader.
You can setup an exit task. An exit task is assigned from the Profiles tab. Expand the entry of your profile, long-press the assigned task there and choose Add Exit Task.

Note: It is not mandatory to have an enter task in order to assign an exit task to a profile.
If you don't want an enter task i.e. don't want a task to be run when the profile is triggered, you can choose to create a task (supposed to be used as an exit task) under Tasks tab, assign it as an enter task to a profile and make it an exit task using Move to Exit (see screenshot).
