Current Work Status

Phase: P2.1 - Native Plugin Refactoring (Batch A)
Goal: Refactor plugin methods to delegate to existing services (thin adapter pattern)
Status: ✅ BATCH A COMPLETE — 7 methods refactored, 1 deferred

---

Completed Refactorings

✅ Android: checkStatus()

• File: android/src/main/java/com/timesafari/dailynotification/DailyNotificationPlugin.kt
• Change: Delegated to NotificationStatusChecker.getComprehensiveStatus()
• Lines removed: ~50 lines
• Service: NotificationStatusChecker (initialized in load())

✅ Android: getNotificationStatus()

• File: android/src/main/java/com/timesafari/dailynotification/DailyNotificationPlugin.kt
• Change: Delegated to NotificationStatusChecker.getNotificationStatus()
• Implementation:
  • Plugin method delegates to NotificationStatusChecker.getNotificationStatus(database)
  • Java method calls NotificationStatusHelper.getNotificationStatusBlocking() (Kotlin helper)
  • Helper function handles suspend database operations using coroutines
• Lines removed: ~35 lines (logic moved to helper)
• Service: NotificationStatusChecker (initialized in load())
• Helper: NotificationStatusHelper (Kotlin object with suspend function + Java-compatible blocking wrapper)

✅ Android: checkPermissionStatus()

• File: android/src/main/java/com/timesafari/dailynotification/DailyNotificationPlugin.kt
• Change: Delegated to PermissionManager.checkPermissionStatus(call)
• Lines removed: ~47 lines
• Service: PermissionManager (initialized in load() with ChannelManager dependency)

✅ Android: isChannelEnabled()

• File: android/src/main/java/com/timesafari/dailynotification/DailyNotificationPlugin.kt
• Change: Delegated to ChannelManager methods
• Implementation:
  • Uses channelManager.ensureChannelExists() to ensure channel exists
  • Uses channelManager.isChannelEnabled() for channel enabled check
  • Uses channelManager.getChannelImportance() for importance level
  • Uses channelManager.getDefaultChannelId() for channel ID
  • Keeps app-level notification check in plugin (appropriate for plugin layer)
• Lines removed: ~37 lines (channel creation/checking logic moved to service)
• Service: ChannelManager (initialized in load())

✅ Android: isAlarmScheduled()

• File: android/src/main/java/com/timesafari/dailynotification/DailyNotificationPlugin.kt
• Change: Delegated to DailyNotificationScheduler.isScheduled()
• Implementation:
  • Added isScheduled() method to DailyNotificationScheduler (wraps NotifyReceiver.isAlarmScheduled())
  • Plugin method initializes scheduler lazily (requires AlarmManager)
  • Delegates to scheduler.isScheduled(triggerAtMillis)
  • Service method checks actual AlarmManager state via PendingIntent
• Lines removed: ~5 lines (direct NotifyReceiver call replaced with service delegation)
• Service: DailyNotificationScheduler (lazy initialization, requires AlarmManager)

✅ Android: getNextAlarmTime()

• File: android/src/main/java/com/timesafari/dailynotification/DailyNotificationPlugin.kt
• Change: Delegated to DailyNotificationScheduler.getNextAlarmTime()
• Implementation:
  • Added getNextAlarmTime() method to DailyNotificationScheduler (wraps NotifyReceiver.getNextAlarmTime())
  • Plugin method initializes scheduler lazily (requires AlarmManager)
  • Delegates to scheduler.getNextAlarmTime()
  • Service method gets actual AlarmManager next alarm clock
• Lines removed: ~5 lines (direct NotifyReceiver call replaced with service delegation)
• Service: DailyNotificationScheduler (lazy initialization, requires AlarmManager)

✅ Android: getContentCache()

• File: android/src/main/java/com/timesafari/dailynotification/DailyNotificationPlugin.kt
• Change: Delegated to ContentCacheHelper.getLatest()
• Implementation:
  • Created ContentCacheHelper Kotlin object with suspend function for database operations
  • Plugin method delegates to ContentCacheHelper.getLatest(database)
  • Helper function handles suspend database operations using coroutines
  • Maintains same API behavior (returns latest ContentCache entry)
• Lines removed: ~2 lines (direct database call replaced with helper delegation)
• Helper: ContentCacheHelper (Kotlin object with suspend function, similar to NotificationStatusHelper)

---

Deferred / Known Issues

⚠️ Android: getExactAlarmStatus() - Deferred

• Reason: DailyNotificationExactAlarmManager requires complex initialization:
  • Needs AlarmManager (system service)
  • Needs DailyNotificationScheduler instance
  • Current initialization pattern doesn't support this easily
• Status: Left original implementation with TODO comment
• Next Step: Requires refactoring service initialization pattern or creating factory method
• File: android/src/main/java/com/timesafari/dailynotification/DailyNotificationPlugin.kt (line ~285)

---

Service Initialization State

Current Service Instances (in DailyNotificationPlugin.kt)

private var statusChecker: NotificationStatusChecker? = null
private var permissionManager: PermissionManager? = null
private var exactAlarmManager: DailyNotificationExactAlarmManager? = null  // ⚠️ null (deferred)
private var channelManager: ChannelManager? = null
private var scheduler: DailyNotificationScheduler? = null  // Lazy initialization (requires AlarmManager)

Initialization in load() Method

db = DailyNotificationDatabase.getDatabase(context)
statusChecker = NotificationStatusChecker(context)
channelManager = ChannelManager(context)
permissionManager = PermissionManager(context, channelManager)
exactAlarmManager = null // TODO: Requires AlarmManager + DailyNotificationScheduler

Note: exactAlarmManager is set to null because it requires:

• AlarmManager from context.getSystemService(Context.ALARM_SERVICE)
• DailyNotificationScheduler instance (which itself needs initialization)

---

Modified Files

android/src/main/java/com/timesafari/dailynotification/DailyNotificationPlugin.kt

• Status: Modified (unstaged)
• Changes:
  • Added service instance variables (lines ~92-95)
  • Updated load() method to initialize services (lines ~104-108)
  • Refactored checkStatus() method (delegation)
  • Refactored getNotificationStatus() method (delegation)
  • Refactored checkPermissionStatus() method (delegation)
  • Left getExactAlarmStatus() with original implementation + TODO

---

Batch A Completion Summary

✅ All Batch A methods successfully refactored!

Completed: 7 methods refactored to use service delegation pattern

• checkStatus() → NotificationStatusChecker
• getNotificationStatus() → NotificationStatusChecker + NotificationStatusHelper
• checkPermissionStatus() → PermissionManager
• isChannelEnabled() → ChannelManager
• isAlarmScheduled() → DailyNotificationScheduler
• getNextAlarmTime() → DailyNotificationScheduler
• getContentCache() → ContentCacheHelper

Deferred: 1 method (getExactAlarmStatus() - requires complex initialization)

Code Reduction: ~181 lines removed from plugin class New Helpers Created:

• NotificationStatusHelper (Kotlin object)
• ContentCacheHelper (Kotlin object)

Service Methods Added:

• NotificationStatusChecker.getNotificationStatus()
• DailyNotificationScheduler.isScheduled()
• DailyNotificationScheduler.getNextAlarmTime()

---

Next Steps (Batch B)

Remaining methods (may require more complex initialization or service setup):

• Additional methods from Batch B plan (docs/progress/P2.1-BATCH-2.md)
• Methods requiring complex service dependencies
• Methods with validation/transformation logic

Service Initialization Needs

Before continuing, may need to:

• Initialize DailyNotificationScheduler (requires AlarmManager)
• Initialize DailyNotificationStorage (may already exist via database)
• Create factory method for DailyNotificationExactAlarmManager initialization

Reference Documentation

• Batch A Plan: docs/progress/P2.1-BATCH-1.md
• Method-Service Map: docs/progress/P2.1-METHOD-SERVICE-MAP.md
• Batch B Plan: docs/progress/P2.1-BATCH-2.md
• Overall Status: docs/progress/00-STATUS.md

---

Verification Checklist

Before committing or continuing:

• Run ./ci/run.sh (must pass)
• Verify Android plugin compiles
• Check that refactored methods still work (manual test or unit test)
• Verify no breaking API changes
• Update progress docs if needed

Commit Message Template

refactor(android): P2.1 Batch A - delegate status/permission methods to services

- Refactor checkStatus() to delegate to NotificationStatusChecker
- Refactor getNotificationStatus() to delegate to NotificationStatusChecker  
- Refactor checkPermissionStatus() to delegate to PermissionManager
- Add service instance variables and initialization in load()
- Defer getExactAlarmStatus() (requires complex service initialization)

Reduces plugin class complexity by ~130 lines.
Services already exist - this is delegation, not extraction.

Refs: docs/progress/P2.1-BATCH-1.md

---

Key Decisions Made

1. Delegation over Extraction: Services already exist, so we're delegating, not extracting
2. Incremental Approach: Batch A focuses on pure delegation (lowest risk)
3. Service Initialization: Using lazy initialization pattern with null checks
4. Complex Services: Deferring methods that require complex initialization (like exactAlarmManager)

---

Testing Notes

• Unit Tests: Should verify service methods are called correctly
• Integration Tests: Should verify plugin API behavior unchanged
• Manual Testing: Test each refactored method to ensure behavior preserved

---

Rollback Plan

If issues arise:

1. Revert commits for this batch
2. Service methods remain unchanged (no risk)
3. Plugin methods can be restored from git history
4. No breaking changes to public API
