Custom notifications that require an action from user

[dottedmag]

I'm trying to write an application that will notify user about some event (e.g. by buzzing), and then wait for the reaction (tap on the screen or pressing a button). Is there a way to do so reliably?

I have found that I can do the notifications by making a custom face application: face application can buzz without fear of being removed. But face applications don't receive user input.

I can add reaction to user actions to a regular application, but these are not kept running.

Is there a way to have both?

Clockfaces can receive touch ('mouse') events. Just be sure that the interaction between these and the system's swipe behaviour is sensible.
