Goal

Closes: #[AND-1494]

Implementation

  • default Android 17 incoming calls to Telecom-first routing using isAndroid17OrHigher()
  • post the notification-owned ringing UI only after Telecom registration succeeds
  • fall back to CallService while retaining notification ringtone ownership
  • keep pre-Android 17 behavior unchanged
  • keep one ServiceLauncher and Telecom provider per client lifecycle
  • track whether Telecom or CallService owns the incoming call
  • leave ClientState.maybeStopForegroundService(call) unchanged from the preceding PR

Public API changes

  • None. The temporary debugUseTelecomFirstForIncomingCalls builder API was removed.
  • Telecom routing state and coordinator types remain internal.

Stack

PR 5 of 5. Depends on #1810.

Review and merge the stack from #1807 upward.

Testing

  • both Android 17 and pre-Android 17 incoming-call coordinators
  • notification ringtone preparation, existing-channel reuse, and missing-channel rejection
  • notification-only incoming-call presentation
  • Telecom permission checks and registration callbacks, failures, and cancellation
  • Android-version defaults in CallServiceConfig
  • CallService observer ownership for Telecom and legacy routes
  • foreground-service type behavior across Android versions
  • Telecom notification update IDs
  • legacy ringtone suppression under notification ownership
  • rejected-call handling
  • incoming notification preparation and missed-call cleanup in StreamDefaultNotificationHandler

Summary by CodeRabbit

  • New Features

    • Added Android 17+ Telecom integration for incoming calls, with automatic fallback when Telecom or required permissions are unavailable.
    • Added dedicated incoming-call ringing notification channels with support for configured ringtone and vibration behavior.
    • Android 17+ devices now enable Telecom by default unless explicitly configured otherwise.
    • Incoming calls can be displayed directly through notifications when service-based handling is unavailable.
  • Bug Fixes

    • Improved call routing and notification updates across Android versions, including cleaner handling of rejected and completed calls.

Review Change Stack

Walkthrough

Changes

The SDK adds Android 17 Telecom-based incoming-call routing. It tracks the selected service route, moves ringing ownership to notifications when required, adds Telecom and notification observers, and expands tests for routing, channels, permissions, and lifecycle behavior.

Incoming ringing ownership

Layer / File(s) Summary
Notification channel and ringtone handling
stream-video-android-core/src/main/kotlin/io/getstream/video/android/core/notifications/..., stream-video-android-core/src/main/res/values/strings.xml
Android 17 uses dedicated ringing channel IDs. Notification-owned ringing configures sound, vibration, and alert flags.
Ringtone behavior validation
stream-video-android-core/src/test/kotlin/io/getstream/video/android/core/notifications/...
Tests cover channel creation, channel selection, ringtone ownership, and notification preparation.

Telecom routing

Layer / File(s) Summary
Route selection and coordinators
stream-video-android-core/src/main/kotlin/io/getstream/video/android/core/CallState.kt, stream-video-android-core/src/main/kotlin/io/getstream/video/android/core/notifications/internal/service/...
The SDK selects Android 17 Telecom or legacy CallService routing. Telecom registration falls back to CallService on failure.
Routing validation
stream-video-android-core/src/test/kotlin/io/getstream/video/android/core/notifications/internal/service/...
Tests cover route state, Android-version defaults, coordinator fallback, Telecom registration, and service lifecycle handling.

Observers and Telecom integration

Layer / File(s) Summary
Observer contracts and implementations
stream-video-android-core/src/main/kotlin/io/getstream/video/android/core/notifications/internal/service/observers/..., stream-video-android-core/src/main/kotlin/io/getstream/video/android/core/notifications/internal/telecom/...
Observers now use context-free interfaces. Telecom notification updates, rejection handling, permission checks, and registration callbacks are implemented.
Observer and repository tests
stream-video-android-core/src/test/kotlin/io/getstream/video/android/core/notifications/internal/service/observers/..., stream-video-android-core/src/test/kotlin/io/getstream/video/android/core/notifications/internal/telecom/...
Tests cover notification IDs, rejected calls, observer installation, ringtone suppression, Telecom permissions, and registration errors.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟠 High · up to 6b054

Android 17 incoming calls can continue ringing after removal, enter Telecom despite being opted out, or arrive without ringtone and vibration. These paths should be corrected before merge.

Poem

A rabbit routes calls through Telecom bright,
Channels ring with a tuned delight.
Legacy paths wait when fallbacks appear,
Observers watch each state sincere.
Tests hop along to make flows clear.

Prepare the notification when the notification owns ringing.

The provider discards IncomingRingtoneOwner. Android 17 invokes this provider with IncomingRingtoneOwner.Notification after Telecom registration. This path now returns an unprepared notification because this handler no longer configures ringtone and vibration on its channel. Incoming calls that use DefaultNotificationHandler can post without ringing or vibration.

Proposed fix
-            notificationProvider = {
-                getRingingCallNotification(
-                    RingingState.Incoming(),
+            notificationProvider = { owner ->
+                val ringingState = RingingState.Incoming()

Honor CallServiceConfig.enableTelecom before Telecom registration.

A call type can set enableTelecom = false, but this gate does not inspect request.callServiceConfiguration. When permissions are available, the coordinator marks that call as TELECOM and registers it with Telecom anyway.

Add !request.callServiceConfiguration.enableTelecom to the fallback condition. Add a regression test for Android 17 with enableTelecom = false.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Dispatch incoming-call removal by ServiceRoute.

When Telecom falls back on Android 17, the fallback coordinator sets ServiceRoute.LEGACY_CALL_SERVICE and starts CallService. Line 196 still selects Android17IncomingCallCoordinator from the OS version. Its dismissIncomingCall only cancels the notification, so the legacy remove trigger does not reach CallService. The foreground service can continue ringing.

Select the coordinator from the stored route for an existing call. Use the Android 17 coordinator only for ServiceRoute.TELECOM.
