Changelog

0.1.10 — Smooth TTS playback & build fix

Fixed

• Choppy / sped-up TTS on Android: playback queue held only 100 chunks while long announcements send 1,000+ chunks (~34 s of audio), causing most audio to be dropped. Queue capacity is now 4,096 with blocking enqueue and WRITE_BLOCKING AudioTrack writes.
• Playback drain timeout increased to 120 s so voice-blast calls finish before teardown.
• Larger AudioTrack buffer for smoother speech output.
• VoiceNotificationManager import fix for VoiceCallReceiver (0.1.8 compile error).

0.1.9 — Lock-screen wake & incoming call alerts

Fixed

• Incoming call UI now wakes the display on a locked device (setTurnScreenOn before super.onCreate(), ring wake lock, keyguard dismiss).
• FCM / killed-app path launches the full-screen incoming Activity immediately, not only via notification tap.
• Incoming notification uses default ringtone, vibration pattern, and DND bypass.

Added

• VoiceCallLockScreenHelper — centralized lock-screen / wake / keyguard handling.
• Android 14+ full-screen intent permission check with log guidance.

0.1.8 — Android native call UI

Added

• Native full-screen call UI on Android (CallKit-equivalent for self-managed VoIP):
  • VoiceIncomingCallActivity — lock-screen incoming screen with Answer / Decline
  • VoiceInCallActivity — auto-opens after Accept with mute, speaker, end, live status, transcript
• VoiceOSConfig.enableNativeCallUi — opt out to use your own Flutter call screen
• VoiceOS.acceptIncomingCall() / rejectIncomingCall() Dart APIs

0.1.7 — Announcement playback drain

Fixed

• Welcome / voice-blast calls ending silently: the SDK now drains the TTS playback queue before stopping AudioTrack / AVAudioPlayerNode when the server sends call_completed.
• Server logs Voice blast produced zero audio samples when TTS returns no PCM, and Voice blast TTS streamed to client with duration when audio is sent.
• Gateway allows up to 3 s for the WebSocket forwarder to flush remaining audio after the engine stops (was 500 ms).

0.1.6 — Graceful server call completion

Fixed

• Incoming calls failing with AudioRecord failed to initialize (error -20) after tapping Answer on Android 14+ when the foreground service was still running with phoneCall-only type during ringing.
• Active-call audio now starts only after VoiceCallService is promoted to microphone | phoneCall foreground service types.
• Mic permission is verified on every answer path (notification + Telecom) before capture.
• AudioRecord initialization retries briefly after Telecom setActive() / FGS promotion to handle device-specific audio routing races.
• call_completed handling: announcement / one-shot agents no longer trigger max_reconnects_exceeded or spurious WebSocket reconnects when the server closes the socket after a normal call end.
• Added CallCompletedEvent on the Dart event stream.

0.1.5 — Android incoming-call foreground service crash fix

Fixed

• Crash on incoming FCM calls (SecurityException) when starting foreground service with microphone type before RECORD_AUDIO is granted (Android 14+ / targetSdk 34+).
• Incoming-call notifications now use FOREGROUND_SERVICE_TYPE_PHONE_CALL only; microphone type is used only after the user answers and mic permission is available.

0.1.4 — Android Kotlin compile fix

Fixed

• Missing VoiceCallService import in VoiceFCMService.kt (broke 0.1.3 Android builds).
• logger.warn → logger.warning to match VoiceOSLogger API.

0.1.3 — Android self-managed incoming call UI

Fixed

• Self-managed Telecom incoming calls now always show Answer/Decline notification UI (Android does not provide a system incoming-call screen for self-managed accounts).
• Tapping Answer on the notification now starts audio/WebSocket when Telecom is enabled (previously waited for a system answer UI that never appears).
• Telecom audio-route events during ringing no longer wake the mic before the call is answered.

0.1.2 — Android incoming call reliability

Fixed

• Android FCM tokens are now synced to the dashboard as fcmToken (not pushkitToken).
• Proactive FCM token fetch on SDK initialize.
• Duplicate FCM deliveries no longer reject the second message as "Busy".
• Emulator devices use notification-based incoming call UI (TelecomManager is unreliable on emulators).
• VoiceCallService no longer re-dispatches incoming FCM to VoiceSessionManager (prevents double handling).

0.1.1 — Android Gradle dependency fix

Fixed

• Android build failures caused by conflicting kotlin-stdlib-jdk8 and androidx.annotation version constraints when consumed from host Flutter apps.
• Plugin android/build.gradle no longer pins Kotlin stdlib or AndroidX annotation versions; Flutter's embedding now resolves them consistently.
• Example app Gradle files updated to current Flutter 3.44 conventions (removed resolutionStrategy.force hacks and manual dependency overrides).
