Supporting Notification Channels
summary
A news app migrates its in-app notification settings to Android notification channels by creating channels identified as channelID + importance + description, keeping a flat (no-group) channel list, and mapping OS channel names into a redesigned in-app UI so users can view and jump to the exact channel. Backend sync is implemented with WorkManager using linear backoff and a per-channel deduplicating worker that throttles events for N seconds to collapse rapid toggles; this reduced blanket opt-outs and produced measurable permission changes after release with continued monitoring.
