From 5abeb0f799123b2660eebde43fe7d3be967e833f Mon Sep 17 00:00:00 2001 From: Matthew Raymer Date: Mon, 20 Oct 2025 09:08:26 +0000 Subject: [PATCH] feat(plugin): implement critical notification stack improvements Critical Priority Improvements (Completed): - Enhanced exact-time reliability for Doze & Android 12+ with setExactAndAllowWhileIdle - Implemented DST-safe time calculation using Java 8 Time API to prevent notification drift - Added comprehensive schema validation with Zod for all notification inputs - Created Android 13+ permission UX with graceful fallbacks and education dialogs High Priority Improvements (Completed): - Implemented work deduplication and idempotence in DailyNotificationWorker - Added atomic locks and completion tracking to prevent race conditions - Enhanced error handling and logging throughout the notification pipeline New Services Added: - NotificationValidationService: Runtime schema validation with detailed error messages - NotificationPermissionManager: Comprehensive permission handling with user education Documentation Added: - NOTIFICATION_STACK_IMPROVEMENT_PLAN.md: Complete implementation roadmap with checkboxes - VUE3_NOTIFICATION_IMPLEMENTATION_GUIDE.md: Vue3 integration guide with code examples This implementation addresses the most critical reliability and user experience issues identified in the notification stack analysis, providing a solid foundation for production-ready notification delivery. --- .../DailyNotificationPlugin.java | 32 +- .../DailyNotificationScheduler.java | 322 ++++- .../DailyNotificationWorker.java | 191 ++- src/services/NotificationPermissionManager.ts | 434 +++++++ src/services/NotificationValidationService.ts | 549 +++++++++ .../NOTIFICATION_STACK_IMPROVEMENT_PLAN.md | 965 +++++++++++++++ .../VUE3_NOTIFICATION_IMPLEMENTATION_GUIDE.md | 1086 +++++++++++++++++ 7 files changed, 3551 insertions(+), 28 deletions(-) create mode 100644 src/services/NotificationPermissionManager.ts create mode 100644 src/services/NotificationValidationService.ts create mode 100644 test-apps/daily-notification-test/docs/NOTIFICATION_STACK_IMPROVEMENT_PLAN.md create mode 100644 test-apps/daily-notification-test/docs/VUE3_NOTIFICATION_IMPLEMENTATION_GUIDE.md diff --git a/android/plugin/src/main/java/com/timesafari/dailynotification/DailyNotificationPlugin.java b/android/plugin/src/main/java/com/timesafari/dailynotification/DailyNotificationPlugin.java index 7e3740b..4c233ae 100644 --- a/android/plugin/src/main/java/com/timesafari/dailynotification/DailyNotificationPlugin.java +++ b/android/plugin/src/main/java/com/timesafari/dailynotification/DailyNotificationPlugin.java @@ -1396,25 +1396,33 @@ public class DailyNotificationPlugin extends Plugin { } /** - * Get exact alarm status + * Get exact alarm status with enhanced Android 12+ support * * @param call Plugin call */ @PluginMethod public void getExactAlarmStatus(PluginCall call) { try { - Log.d(TAG, "Exact alarm status requested");
