# DailyNotification Plugin - Stack Improvement Plan |
|||
|
|||
**Author**: Matthew Raymer |
|||
**Date**: October 20, 2025 |
|||
**Version**: 1.0.0 |
|||
**Status**: Implementation Roadmap |
|||
|
|||
## Executive Summary |
|||
|
|||
This document outlines high-impact improvements for the DailyNotification plugin based on comprehensive analysis of current capabilities, strengths, and areas for enhancement. The improvements focus on reliability, user experience, and production readiness. |
|||
|
|||
## Current State Analysis |
|||
|
|||
### ✅ What's Working Well |
|||
|
|||
#### **Core Capabilities** |
|||
- **Daily & reminder scheduling**: Plugin API supports simple daily notifications, advanced reminders (IDs, repeat, vibration, priority, timezone), and combined flows (content fetch + user-facing notification) |
|||
- **API-driven change alerts**: Planned `TimeSafariApiService` with DID/JWT authentication, configurable polling, history, and preferences |
|||
- **WorkManager offload on Android**: Heavy lifting in `DailyNotificationWorker` with JIT freshness checks, soft prefetch, DST-aware rescheduling, duplicate suppression, and action buttons |
|||
|
|||
#### **Architectural Strengths** |
|||
- **Background resilience**: WorkManager provides battery/network constraints and retry semantics |
|||
- **Freshness strategy**: Pragmatic "borderline" soft refetch and "stale" hard refresh approach |
|||
- **DST safety & dedupe**: Next-day scheduling with DST awareness and duplicate prevention |
|||
- **End-to-end planning**: Comprehensive UX, store integration, testing, and deployment coverage |
|||
|
|||
## High-Impact Improvements |
|||
|
|||
### 🔧 Android / Native Side Improvements |
|||
|
|||
#### **1. Exact-Time Reliability (Doze & Android 12+)** |
|||
- [ ] **Priority**: Critical |
|||
- [ ] **Impact**: Notification delivery accuracy |
|||
|
|||
- [ ] **Current Issue**: Notifications may not fire at exact times due to Doze mode and Android 12+ restrictions |
|||
|
|||
- [ ] **Implementation**: |
|||
```java |
|||
// In DailyNotificationScheduler.java |
|||
public void scheduleExactNotification(NotificationContent content) { |
|||
AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE); |
|||
|
|||
// Use setExactAndAllowWhileIdle for precise timing |
|||
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { |
|||
alarmManager.setExactAndAllowWhileIdle( |
|||
AlarmManager.RTC_WAKEUP, |
|||
content.getScheduledTime(), |
|||
createNotificationPendingIntent(content) |
|||
); |
|||
} else { |
|||
alarmManager.setExact(AlarmManager.RTC_WAKEUP, content.getScheduledTime(), createNotificationPendingIntent(content)); |
|||
} |
|||
} |
|||
|
|||
// Add exact alarm permission request |
|||
public void requestExactAlarmPermission() { |
|||
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.S) { |
|||
AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE); |
|||
if (!alarmManager.canScheduleExactAlarms()) { |
|||
Intent intent = new Intent(Settings.ACTION_REQUEST_SCHEDULE_EXACT_ALARM); |
|||
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); |
|||
context.startActivity(intent); |
|||
} |
|||
} |
|||
} |
|||
``` |
|||
|
|||
- [ ] **Testing**: Verify notifications fire within 1 minute of scheduled time across Doze cycles |
|||
|
|||
#### **2. DST-Safe Time Calculation** |
|||
- [ ] **Priority**: High |
|||
- [ ] **Impact**: Prevents notification drift across DST boundaries |
|||
|
|||
- [ ] **Current Issue**: `plusHours(24)` can drift across DST boundaries |
|||
|
|||
- [ ] **Implementation**: |
|||
```java |
|||
// In DailyNotificationScheduler.java |
|||
public long calculateNextScheduledTime(int hour, int minute, String timezone) { |
|||
ZoneId zone = ZoneId.of(timezone); |
|||
LocalTime targetTime = LocalTime.of(hour, minute); |
|||
|
|||
// Get current time in user's timezone |
|||
ZonedDateTime now = ZonedDateTime.now(zone); |
|||
LocalDate today = now.toLocalDate(); |
|||
|
|||
// Calculate next occurrence at same local time |
|||
ZonedDateTime nextScheduled = ZonedDateTime.of(today, targetTime, zone); |
|||
|
|||
// If time has passed today, schedule for tomorrow |
|||
if (nextScheduled.isBefore(now)) { |
|||
nextScheduled = nextScheduled.plusDays(1); |
|||
} |
|||
|
|||
return nextScheduled.toInstant().toEpochMilli(); |
|||
} |
|||
``` |
|||
|
|||
- [ ] **Testing**: Test across DST transitions (spring forward/fall back) |
|||
|
|||
#### **3. Work Deduplication & Idempotence** |
|||
- [ ] **Priority**: High |
|||
- [ ] **Impact**: Prevents duplicate notifications and race conditions |
|||
|
|||
- [ ] **Current Issue**: Repeat enqueues can cause race conditions |
|||
|
|||
- [ ] **Implementation**: |
|||
```java |
|||
// In DailyNotificationWorker.java |
|||
public static void enqueueDisplayWork(Context context, String notificationId) { |
|||
String workName = "display_notification_" + notificationId; |
|||
|
|||
OneTimeWorkRequest displayWork = new OneTimeWorkRequest.Builder(DailyNotificationWorker.class) |
|||
.setInputData(createNotificationData(notificationId)) |
|||
.setConstraints(getNotificationConstraints()) |
|||
.build(); |
|||
|
|||
WorkManager.getInstance(context) |
|||
.enqueueUniqueWork(workName, ExistingWorkPolicy.REPLACE, displayWork); |
|||
} |
|||
|
|||
public static void enqueueSoftRefetchWork(Context context, String notificationId) { |
|||
String workName = "soft_refetch_" + notificationId; |
|||
|
|||
OneTimeWorkRequest refetchWork = new OneTimeWorkRequest.Builder(SoftRefetchWorker.class) |
|||
.setInputData(createRefetchData(notificationId)) |
|||
.setConstraints(getRefetchConstraints()) |
|||
.build(); |
|||
|
|||
WorkManager.getInstance(context) |
|||
.enqueueUniqueWork(workName, ExistingWorkPolicy.KEEP, refetchWork); |
|||
} |
|||
``` |
|||
|
|||
#### **4. Notification Channel Discipline** |
|||
- [ ] **Priority**: Medium |
|||
- [ ] **Impact**: Consistent notification behavior and user control |
|||
|
|||
**Implementation**: |
|||
```java |
|||
// New class: NotificationChannelManager.java |
|||
public class NotificationChannelManager { |
|||
private static final String DAILY_NOTIFICATIONS_CHANNEL = "daily_notifications"; |
|||
private static final String CHANGE_NOTIFICATIONS_CHANNEL = "change_notifications"; |
|||
private static final String SYSTEM_NOTIFICATIONS_CHANNEL = "system_notifications"; |
|||
|
|||
public static void createChannels(Context context) { |
|||
NotificationManager notificationManager = |
|||
(NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE); |
|||
|
|||
// Daily notifications channel |
|||
NotificationChannel dailyChannel = new NotificationChannel( |
|||
DAILY_NOTIFICATIONS_CHANNEL, |
|||
"Daily Notifications", |
|||
NotificationManager.IMPORTANCE_DEFAULT |
|||
); |
|||
dailyChannel.setDescription("Scheduled daily reminders and updates"); |
|||
dailyChannel.enableLights(true); |
|||
dailyChannel.enableVibration(true); |
|||
dailyChannel.setShowBadge(true); |
|||
|
|||
// Change notifications channel |
|||
NotificationChannel changeChannel = new NotificationChannel( |
|||
CHANGE_NOTIFICATIONS_CHANNEL, |
|||
"Change Notifications", |
|||
NotificationManager.IMPORTANCE_HIGH |
|||
); |
|||
changeChannel.setDescription("Notifications about project changes and updates"); |
|||
changeChannel.enableLights(true); |
|||
changeChannel.enableVibration(true); |
|||
changeChannel.setShowBadge(true); |
|||
|
|||
notificationManager.createNotificationChannels(Arrays.asList(dailyChannel, changeChannel)); |
|||
} |
|||
|
|||
public static NotificationCompat.Builder createNotificationBuilder( |
|||
Context context, |
|||
String channelId, |
|||
String title, |
|||
String body |
|||
) { |
|||
NotificationCompat.Builder builder = new NotificationCompat.Builder(context, channelId) |
|||
.setSmallIcon(R.drawable.ic_notification) |
|||
.setContentTitle(title) |
|||
.setContentText(body) |
|||
.setPriority(NotificationCompat.PRIORITY_DEFAULT) |
|||
.setAutoCancel(true); |
|||
|
|||
// Add BigTextStyle for long content |
|||
if (body.length() > 100) { |
|||
builder.setStyle(new NotificationCompat.BigTextStyle().bigText(body)); |
|||
} |
|||
|
|||
return builder; |
|||
} |
|||
} |
|||
``` |
|||
|
|||
#### **5. Click Analytics & Deep-Link Safety** |
|||
- [ ] **Priority**: Medium |
|||
- [ ] **Impact**: User engagement tracking and security |
|||
|
|||
**Implementation**: |
|||
```java |
|||
// New class: NotificationClickReceiver.java |
|||
public class NotificationClickReceiver extends BroadcastReceiver { |
|||
@Override |
|||
public void onReceive(Context context, Intent intent) { |
|||
