Long-term triggers on App Tasks

[bardram]

There is a need to support long-term triggers for e.g. adding tasks to the app task queue.

Scenarios

• recurrent scheduled trigger, like once pr. day or once pr week
• delayed trigger - e.g. after 2 weeks, once or recurrent, specify a delay (duration)
• timed trigger - specific date (24/12)
• random trigger - N times a day within a time period
• recurrent conditional trigger - check a condition on a regular interval

.. and a combination of such triggers?

• a delayed recurrent trigger
• recurrent conditional trigger
• timed recurrent trigger - first occurrence

Persistence

How to make sure this happens even if the app is not running.....?
