Alert coverage depends on the source. Not every provider returns alerts for every region.
Overcast is a Dynamic Island provider for Essentials. Essentials binds to Overcast's island service once the user enables it there, and Overcast pushes its own icons, text and the expanded view.
- The service is declared with the
com.sameerasw.island.PROVIDERaction and only accepts the Essentials package. - The compact pill and line are sent as data; the expanded view is rendered by Overcast and embedded by Essentials.
- Island options (when to show, alert peeks, effects) live in Overcast's settings.
