Daily Notification Plugin - Task TODO List

Project Overview

Objective: Build an offline-first daily notifications system for Android (Kotlin) and iOS (Swift) that follows the Prefetch → Cache → Schedule → Display pipeline without requiring network at display time.

Priority: Reliability over richness

Phase 1: Foundation (Week 1) - HIGH PRIORITY

1.1 Restore Android Implementation

• Create native Android plugin structure
• Implement WorkManager for background content fetching
• Add AlarmManager for notification scheduling
• Create notification channels and permissions
• Implement battery optimization handling
• Add proper error handling and logging

1.2 Fix Interface Definitions

• Align TypeScript interfaces with project requirements
• Add missing properties referenced in tests
• Implement proper validation utilities
• Create comprehensive error types
• Add retry mechanism interfaces

1.3 Fix Test Suite

• Update all test files to match current interfaces
• Implement proper mock objects
• Fix TypeScript compilation errors
• Fix test execution issues (plugin registration, validation)
• Ensure 100% test coverage
• Add integration tests for native platforms

Phase 2: Core Pipeline Implementation (Week 2) - HIGH PRIORITY

2.1 Prefetch System

• Implement background content fetching
• Add network timeout handling (30s max)
• Create content validation system
• Implement retry mechanisms with exponential backoff
• Add network state monitoring

2.2 Caching Layer

• Create local storage for notifications
• Implement cache eviction policies (LRU)
• Add offline content management
• Create cache quota management
• Implement cache versioning

2.3 Enhanced Scheduling

• Implement reliable notification delivery
• Add platform-specific optimizations
• Handle battery optimization settings
• Create adaptive scheduling based on device state
• Add quiet hours support

Phase 3: Production Features (Week 3) - MEDIUM PRIORITY

3.1 Fallback System

• Implement emergency content rotation
• Add stale content marking ("from X ago")
• Create graceful degradation paths
• Implement last-known-good fallback
• Add offline fallback content

3.2 Metrics & Monitoring

• Create local analytics collection
• Implement performance monitoring
• Add error tracking and reporting
• Create metrics dashboard
• Implement user engagement tracking

3.3 Security & Privacy

• Add input validation for all user inputs
• Implement secure storage for sensitive data
• Create proper permission handling
• Add network security (HTTPS, certificate pinning)
• Implement audit logging

Phase 4: Advanced Features (Week 4) - LOW PRIORITY

4.1 User Experience

• Create onboarding flow
• Add permission request handling
• Implement time picker interface
• Add test notification functionality
• Create troubleshooting guides

4.2 Platform Optimizations

• Android: OEM battery settings education
• iOS: Focus/Summary mode handling
• Web: Service worker implementation
• Cross-platform synchronization
• Performance optimization

4.3 Enterprise Features

• Multi-tenant support
• Advanced analytics
• Custom notification templates
• Integration with external services
• A/B testing support

Technical Requirements

Android Implementation

• Use WorkManager for background tasks
• Implement AlarmManager for exact scheduling
• Create notification channels with high importance
• Handle SCHEDULE_EXACT_ALARM permission
• Add battery optimization exemption requests

iOS Implementation

• Use BGTaskScheduler for background refresh
• Implement UNCalendarNotificationTrigger
• Create DAILY_UPDATE notification category
• Handle Background App Refresh settings
• Add Focus/Summary mode support

Data Model

• Implement NotificationContent v1 schema
• Add versioning support
• Create storage abstraction layers
• Implement cache policies
• Add analytics event tracking

Testing Requirements

Unit Tests

• Fallback when fetch fails
• Exact vs inexact scheduling path selection
• Metrics recording for each stage
• Cache eviction policies
• Error handling scenarios

Integration Tests

• Android foreground/background/killed scenarios
• iOS background/Low Power/Focus modes
• Offline at trigger time
• Battery saver mode handling
• Network state changes

Performance Tests

• Memory usage monitoring
• Battery impact measurement
• Notification delivery latency
• Cache performance
• Background task efficiency

Documentation Requirements

API Documentation

• Complete method documentation
• Usage examples for each platform
• Error handling guides
• Performance optimization tips
• Troubleshooting playbook

User Guides

• Installation instructions
• Configuration guide
• Platform-specific setup
• Battery optimization tips
• Common issues and solutions

Security Checklist

• Input validation for all parameters
• Secure storage implementation
• Permission handling
• Network security
• Error handling without information leakage
• Audit logging
• Privacy compliance
• Secure defaults

Definition of Done

• Notifications deliver daily at user-selected time without network
• Graceful fallback chain proven by tests
• Metrics recorded locally and viewable
• Clear onboarding and self-diagnostic screen
• Battery/OS constraints documented
• User education available for platform-specific settings

Current Status

Build Status: ✅ Working Test Status: ❌ 13/13 tests failing Android Implementation: ✅ Complete with offline-first pipeline iOS Implementation: ✅ Basic implementation exists Web Implementation: ⚠️ Placeholder only Core Pipeline: ✅ Implemented (Prefetch → Cache → Schedule → Display)

Next Immediate Actions

1. ✅ Android Implementation Complete - Native plugin with offline-first pipeline
2. Fix Interface Definitions - Align with project requirements
3. Update Test Suite - Fix compilation errors and implement mocks
4. ✅ Core Pipeline Implemented - Prefetch → cache → schedule → display flow working
