💡 Overview

Fixes Android audio routing breaking mid-call on Android 11+. The OS resets
AudioManager.MODE_IN_COMMUNICATION ~6s after it's set when the app has no active
voice-comm playback or recording — dropping the
call to the default media route and disabling AEC (https://issuetracker.google.com/issues/209493718).

This PR adds a workaround that plays a silent, looping voice-communication AudioTrack for the
duration of a communicator-role call, so the OS always sees active playback and holds the
mode. Android-only; no-op below API 30 and for the listener role / Telecom-managed calls.

📝 Implementation notes

  • CommunicationModeKeepAlive.kt: plays a silent-AudioTrack to keep-alive; falls back to a periodic
    MODE_IN_COMMUNICATION re-assert watchdog if the track can't be built.

🎫 Ticket: https://linear.app/stream/issue/XYZ-123

📑 Docs: https://github.com/GetStream/docs-content/pull/1569

Summary by CodeRabbit

  • New Features

    • Added an option to disable the Android communication-mode audio workaround.
    • Added a getter to check the currently configured workaround preference.
    • Preference changes are retained and applied when joining the next call.
  • Bug Fixes

    • Improved Android audio routing stability during call start, stop, and teardown.
    • Added safeguards to prevent late audio operations after shutdown.
    • Improved handling when audio playback setup fails or the current activity is unavailable.
    • The setting has no effect on iOS or Telecom-managed calls.

📝 Walkthrough

Walkthrough

The SDK now stores and reapplies the communication-mode workaround preference. Android uses silent playback or polling to preserve communication mode. Audio teardown blocks late routing, restores normal mode, and reports keep-alive state.

Changes

Communication mode workaround

Layer / File(s) Summary
SDK configuration and forwarding
packages/react-native-sdk/src/modules/call-manager/..., packages/react-native-sdk/src/utils/internal/registerSDKGlobals.ts, packages/react-native-sdk/__tests__/call-manager/CallManager.test.ts, packages/react-native-sdk/android/src/main/java/com/streamvideo/reactnative/callmanager/StreamInCallManagerModule.kt
Adds the setter contract and sticky preference storage. Eligible Android joins always forward the recorded value before start(). Tests cover default, setter, mid-call, listener, iOS, Telecom-managed, and version-skew paths.
Android keep-alive implementation
packages/react-native-sdk/android/src/main/java/com/streamvideo/reactnative/audio/CommunicationModeKeepAlive.kt
Adds silent voice-communication playback on Android API 30+ and a polling fallback. Older Android versions use a no-op implementation.
Audio lifecycle integration
packages/react-native-sdk/android/src/main/java/com/streamvideo/reactnative/audio/AudioDeviceManager.kt, packages/react-native-sdk/android/src/main/java/com/streamvideo/reactnative/callmanager/StreamInCallManagerModule.kt
Starts and stops the keep-alive with audio lifecycle events. Teardown blocks late routing, accepts nullable activities, restores MODE_NORMAL, releases resources, and exposes diagnostic state.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to e2163

Android 11+ communicator calls now preserve communication mode with silent playback or polling fallback. The fallback can currently appear as active playback in audio diagnostics, which may complicate support investigation but does not change call audio behavior.

- Around line 173-180: The stop flow in AudioDeviceManager.stop() currently
depends on currentActivity being available before releasing audio state.
Decouple teardown from the Activity-dependent block so audioManagerActivated is
reset and communicationWorkaround.stop() always runs, including when
currentActivity is null; keep only Activity-specific cleanup conditional on the
activity.
- Around line 301-305: Update AudioDeviceManager.close() to queue
communicationWorkaround disposal and all related audio cleanup on the same audio
executor used by start() and stop(), rather than performing it directly. Ensure
close() cannot race pending audio work or allow a queued start() to access
audioTrack or watchdog after cleanup, while preserving the existing callback
unregistration and proximityManager teardown behavior.

In
`@packages/react-native-sdk/android/src/main/java/com/streamvideo/reactnative/audio/CommunicationWorkaround.kt`:
- Around line 223-231: The watchdog repair in CommunicationWorkaround is still
able to run after stop() has restored MODE_NORMAL, so update the
AudioDeviceManager.runInAudioThread closure to check the active state before
touching AudioManager.mode. Keep the existing mode re-assertion logic in the
same watchdog block, but gate the read/write with the component’s current
running/active flag so stale queued work exits without setting
MODE_IN_COMMUNICATION after shutdown.

Re-plumbs the Android communication-mode keep-alive opt-out onto the
call-manager architecture introduced by hi-fi audio (#2305).

#2305 turned the public `callManager.start(config)` into a config store:
it no longer drives the native module, and the SDK's internal call
manager applies the stored config at join time. The per-call
`disableCommunicationModeWorkaround` forwarding lived in the deleted
`start()` branch, so it moves to `registerSDKGlobals.ts` alongside
`setAudioRole`, before the native `start()` (native rejects the change
once the audio manager is activated). Telecom-managed calls are still
excluded, so a per-call config cannot clobber the sticky preference on a
call where the keep-alive never runs.

Also fixes a latent test-harness bug: `registerSDKGlobals()` no-ops once
`globalThis.streamRNVideoSDK` is set, and that global outlives
`jest.resetModules()`, so every test after the first bound the internal
call manager to the first test's mocked native module.

The Kotlin keep-alive is unaffected - #2305 did not touch android/.

- Around line 368-369: Update the setter wrapping
NativeManager.setDisableCommunicationModeWorkaround in safeNativeCall to expose
the pre-activation requirement: document or enforce that it must be called
before audioManagerActivated becomes true, or persist the requested value and
apply it from the next start() so active-call updates are not falsely reported
as successful.

In `@packages/react-native-sdk/src/utils/internal/registerSDKGlobals.ts`:
- Around line 126-129: Update the disableKeepAlive derivation near
CallManager.start to treat an omitted config.audioRole as the default
communicator role, so disableCommunicationModeWorkaround is forwarded when no
audioRole is provided; preserve undefined for explicitly non-communicator roles.

does it make sense to add this property as part of StreamInCallManagerConfig and just pick it up in the globals call manager to invoke the corresponding native method?
