feat(notification): Live Updates focus notifications for active tasks - #75
X-SCI-TECH wants to merge 1 commit into
Conversation
…asks Implement Android 15+ Live Updates (promoted ongoing foreground notifications) via the AndroidX compat path: - Add POST_PROMOTED_NOTIFICATIONS permission - New LiveUpdateChannelId channel for active-task notifications - buildForegroundNotification uses LiveUpdateChannelId + setRequestPromotedOngoing(true) while sessions are active, with a live status line (task name + running tool) - AetherForegroundService.updateForeground() refreshes the ongoing notification in place (same ID) on every status change - Bump androidx.core (core-ktx) 1.13.1 -> 1.17.0 for setRequestPromotedOngoing
📝 WalkthroughWalkthroughThe app adds Android promoted-notification permission support, a live-update notification channel, session-based notification status, and in-place foreground notification refreshes. The ChangesLive notification updates
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to This change exposes active task and tool details on more prominent notification surfaces and alters foreground-service notification handling. A rapid stop/restart can leave active work without restored foreground status, potentially allowing Android to terminate it, while the documented Android 15 behavior does not match the implementation and sensitive details may appear on lock-screen surfaces. Merge should wait for the lifecycle fix and explicit platform/privacy decisions. Sequence Diagram(s)sequenceDiagram

Android Service stopForeground STOP_FOREGROUND_REMOVE startForeground notification official documentation foreground service
💡 Result:
To manage the foreground state and notification associated with an Android Service, you should use the stopForeground(int) method [1][2]. The stopForeground(int) method replaces the older, deprecated stopForeground(boolean) method [1][3]. When calling this, you must pass one of the following integer flags to define the behavior of the service's notification [1][2][3]: 1. STOP_FOREGROUND_REMOVE: This flag removes the service from the foreground state and immediately cancels (removes) the associated notification from the display [1][3]. 2. STOP_FOREGROUND_DETACH: This flag removes the service from the foreground state but leaves the notification visible to the user. The service's association with the notification is severed, meaning the notification will remain even if the service is later stopped or destroyed [1][3]. If you pass zero (0) to stopForeground(int), the system uses a legacy behavior equivalent to STOP_FOREGROUND_LEGACY (which typically behaves like passing false to the deprecated boolean method) [2][3]. For consistent behavior across different Android versions, it is recommended to use ServiceCompat.stopForeground(Service, int) from the AndroidX Core library [4]. This provides a stable interface to manage these flags [4]. When starting a foreground service, you must use startForeground(int, Notification) or the AndroidX equivalent ServiceCompat.startForeground(...) [5]. Note that starting with Android 14 (API level 34), you are required to declare foreground service types in your manifest and pass those types to the startForeground call [5][6][7]. Failure to specify these types when required will result in a runtime exception [5][7].

Reset hasEnteredForeground when removing foreground state.
stopForeground(STOP_FOREGROUND_REMOVE) removes foreground state, but the flag remains true. If active work returns before onDestroy, onStartCommand skips enterForeground, and updateForeground only calls NotificationManagerCompat.notify. Set hasEnteredForeground = false in the stop branch so the service re-enters foreground mode.

site:developer.android.com Live Updates Android 16 API 36 POST_PROMOTED_NOTIFICATIONS setRequestPromotedOngoing AndroidX Core 1.17
💡 Result:
To support Live Updates in Android 16 (API level 36), developers must declare the android.permission.POST_PROMOTED_NOTIFICATIONS permission in their Android Manifest [1][2][3]. This permission is required to post promoted notifications [1][4]. In your code, you can request promoted treatment for a notification using the NotificationCompat.Builder.setRequestPromotedOngoing(boolean) method, which was introduced in AndroidX Core 1.17.0 [5][6]. Key implementation details for Live Update notifications include: 1. Permission: Add to your AndroidManifest.xml [2][3]. 2. Notification Requirements: The notification must be ongoing (using setOngoing(true)), have a content title, and use a supported style (Standard, BigTextStyle, CallStyle, ProgressStyle, or MetricStyle) [2][3]. 3. Promotion Request: Use.setRequestPromotedOngoing(true) on the NotificationCompat.Builder [2][5][3]. 4. Validation: You can use NotificationManager.canPostPromotedNotifications to check if the app is permitted to post promoted notifications (e.g., based on user settings) [2][7][3]. The NotificationCompat.hasPromotableCharacteristics method can also be used to validate if the notification meets the requirements for promotion [2][3][8]. These APIs allow apps to utilize promoted notification slots for real-time, ongoing updates [2][3].

Correct the Live Updates version claim.
Change the KDoc and inline comment to Android 16/API 36. On Android 15, this branch can only provide the standard ongoing foreground notification, so document that fallback in the acceptance criteria.

What
Implements Android 15+ Live Updates (promoted ongoing foreground notifications) for active tasks, using the AndroidX compat path (
NotificationCompat).This addresses the "随时看到进度" (see progress anytime) part of #40 — a promoted ongoing notification shows real-time task progress while the app is in the background, and the ongoing notification itself helps keep the app alive.
Changes:
AndroidManifest.xml: addPOST_PROMOTED_NOTIFICATIONSpermissionAetherNotificationController.kt:LiveUpdateChannelIdchannel (aether_live_updates,IMPORTANCE_LOW, no badge)buildForegroundNotificationuses the Live Update channel +setRequestPromotedOngoing(true)while sessions are active, with a live status line (task name + running tool name)AetherForegroundService.kt:updateForeground()refreshes the ongoing notification in place (same ID) viaNotificationManagerCompat.notify()on every status change — this is what makes progress "live"gradle/libs.versions.toml: bumpandroidx.core(core-ktx)1.13.1→1.17.0(required forsetRequestPromotedOngoing)Design notes
setRequestPromotedOngoing(true)(maps toEXTRA_REQUEST_PROMOTED_ONGOING) — the official compat path for Live Updates. Verified present in androidx.core 1.17.0 (there is nosetLiveUpdateinNotificationCompat; that is a platform API 35-only method).POST_PROMOTED_NOTIFICATIONSsatisfies the promoted-ongoing conditions.This is an implementation/suggestion only — I was unable to compile or run-test this change. The build host is aarch64 Linux (Alpine/musl), where the Android SDK's official build-tools (
aidl/aapt2) are x86_64-only and cannot execute (tracked in #74).Please review carefully and run the app on a device (Android 15+) to verify:
