WalkthroughChangesThe change adds Android 17 ringtone ownership selection. Incoming notifications now use configured channel sound and vibration settings on Android 17 and higher. Older versions retain SDK-managed ringtone playback. Notification creation is deferred through a provider. Incoming ringtone contract and channel setup
Service coordination and validation
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to Android 17+ incoming calls move ringtone ownership to notifications, but upgraded installations may retain the previously created silent or non-vibrating incoming-call channel. A versioned channel or safe migration is needed before merge to ensure calls continue alerting users after upgrade. Poem

Android NotificationManager createNotificationChannel existing channel sound vibration cannot be changed official documentation
💡 Result:
According to official Android documentation, you cannot programmatically change the sound or vibration settings of a notification channel after it has been created and submitted to the NotificationManager [1][2][3]. These properties (including sound, vibration, and importance) are immutable once the channel is registered with the system [2][4][3]. Any subsequent calls to createNotificationChannel with an existing channel ID will ignore these fields [5][6][7]. If you need to update these behaviors, the user must manually modify them through the system settings for your app [2]. You can direct users to these settings by providing a UI element in your app that launches the system notification settings for the specific channel [2]. Key points regarding notification channel updates: - Immutable properties: Once a channel is created, properties such as sound, vibration pattern, and importance cannot be changed programmatically [1][2][4][3]. - Mutable properties: You can only update the name, description, group, and importance (only if lowering importance and the user has not modified the channel) of an existing channel [5][6][7]. - User control: Users have full control over these settings and can override or change them at any time via the Android system UI [2].

site:developer.android.com NotificationChannel constructor default sound setSound default notification sound
💡 Result:
The NotificationChannel constructor does not accept a sound parameter; it only requires an ID, a user-visible name, and an importance level [1][2][3]. To set a sound for a NotificationChannel, you must use the setSound(Uri, AudioAttributes) method [1][2]. If you wish to use the system default notification sound, you can obtain the corresponding Uri by calling Settings.System.DEFAULT_NOTIFICATION_URI [4]. Key details regarding NotificationChannel sound: - Method: Use channel.setSound(soundUri, audioAttributes) [1][2]. - Constraints: This method can only be called before the channel is submitted to the NotificationManager via createNotificationChannel [1][2]. - Audio Attributes: You should provide appropriate AudioAttributes (typically using AudioAttributes.USAGE_NOTIFICATION) when setting the sound [1][2]. - Deprecation: Older methods such as Notification.Builder.setSound and the use of the Notification.DEFAULT_SOUND flag have been deprecated in favor of using NotificationChannel settings [5][4][6]. For a default configuration, you would typically implement it as follows: val channel = NotificationChannel(CHANNEL_ID, name, NotificationManager.IMPORTANCE_DEFAULT) val audioAttributes = AudioAttributes.Builder.setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION).setUsage(AudioAttributes.USAGE_NOTIFICATION).build channel.setSound(Settings.System.DEFAULT_NOTIFICATION_URI, audioAttributes)

Migrate the incoming-call channel IDs before relying on notification-owned ringing.
createNotificationChannel does not update sound or vibration for existing channels. Earlier versions used the same incoming_calls IDs without these settings, and no migration exists. On Android 17+, CallServiceRingingStateObserver skips SDK playback, so upgraded installations retain the old channel behavior instead of the configured ringtone and vibration. Use versioned channel IDs or migrate without overwriting user-controlled settings.

Android NotificationManager createNotificationChannel existing channel sound vibration cannot change official documentation
💡 Result:
According to official Android developer documentation, you cannot programmatically change the sound or vibration settings of a NotificationChannel once it has been submitted to the NotificationManager [1][2][3]. These settings are effectively write-once; they are only modifiable before the channel is first created and submitted [2][3]. After creation, the user has final control over these behaviors through the system settings [1][4]. While you can programmatically update certain other properties of an existing channel—such as its name, description, or group—auditory and vibration behaviors remain locked to prevent apps from overriding user preferences [5][4]. If you need to provide users with different notification sound or vibration options, the recommended approaches include: 1. Directing Users to System Settings: Provide a way to open the system notification settings for your channel so the user can modify the sound and vibration themselves [1][4]. You can use an Intent with the action ACTION_CHANNEL_NOTIFICATION_SETTINGS to link directly to this UI [4]. 2. Creating Multiple Channels: If specific notification types require different sounds or vibration patterns, create separate NotificationChannels for each configuration upfront [6]. 3. Manual Implementation (Workaround): Some developers implement custom notification behavior by setting the channel's sound/vibration to null or silent and handling the sound/vibration manually when the notification is posted (e.g., using a MediaPlayer or VibrationManager), though this approach bypasses standard channel settings [7]. While some applications achieve apparent "updates" by deleting and recreating channels with the same ID, this is generally discouraged and unreliable, as Android may prevent changes to channels that have been deleted by the user or the app [6][8]. If you choose to delete and recreate a channel, you must use a new, unique channel ID for the new configuration [6].

Use a new channel ID for Android 17 ringing notifications.
createRingingChannel and create both register notificationChannels.incomingCallChannel.id. On upgraded installations, that channel may already exist without the ringing sound or vibration settings. Android does not apply those settings after channel creation, so Android 17 notifications can retain the old behavior. Use a versioned ringing-channel ID instead of recreating the existing ID.
