The Android companion can now discover SSH services over local DNS-SD, and the Linux Talkies daemon advertises its reachable SSH endpoint while it is running. Avahi and SSH remain optional; no username or transcript data is published.

The Android UI also adds the guided voice-keyboard setup and microphone permission flow, improved host discovery presentation, and Compose keyboard controls.

Validation: Linux Zig tests and build passed (115 tests passed, 4 skipped); Android core, inference, and app unit tests passed in debug and release on the originating checkout. The clean worktree's Android rerun was blocked because /opt/android-sdk is read-only and the required NDK is absent there; Android CI installs the pinned NDK.

Summary by CodeRabbit

📝 Walkthrough

Linux now optionally advertises reachable SSH services for Android discovery. The Android companion screen can scan for hosts and create profiles from discovered services. Android also updates microphone permission handling, keyboard setup guidance, and the input method interface.

Changes: SSH companion discovery

Layer / File(s) Summary
Linux SSH advertisement
linux/src/app/companion_discovery.zig, linux/src/app/daemon.zig, docs/platforms/linux.md
The daemon starts and stops an optional Avahi publisher. The publisher advertises a non-loopback SSH listener on the configured port, or port 22 by default. Documentation describes service requirements and behavior when discovery is unavailable.
Android service discovery and profiles
mobile/android/app/src/main/AndroidManifest.xml, mobile/android/app/src/main/java/com/talkies/android/SshHostDiscovery.kt, mobile/android/app/src/test/java/com/talkies/android/SshDiscoveryTest.kt
Android discovers and resolves SSH services, extracts host details and optional username metadata, and converts discovered hosts to validated profiles. Tests cover profile creation with discovered or saved usernames.
Discovery controls and host screen
mobile/android/app/src/main/java/com/talkies/android/SshCompanionScreen.kt
The companion screen starts discovery, stops scans after eight seconds, and displays discovered and saved hosts with connection controls. Agent and shell dictation callbacks stage text without submitting it.

Android permission and Compose UI

Layer / File(s) Summary
Microphone permission and keyboard setup
mobile/android/app/src/main/java/com/talkies/android/MainActivity.kt, mobile/android/app/src/main/java/com/talkies/android/KeyboardSetupCard.kt
The activity routes recording and remote dictation through a centralized microphone permission flow. It adds permission explanation and settings dialogs, and displays keyboard and microphone setup status.
Compose input method interface
mobile/android/app/src/main/java/com/talkies/android/TalkiesTheme.kt, mobile/android/app/src/main/java/com/talkies/android/TalkiesGlyph.kt, mobile/android/app/src/main/java/com/talkies/android/TalkiesInputMethodService.kt
The input method now renders recording, processing, and status state with Compose. The change adds a Material 3 theme and custom glyph composable.

Merge Risk: 🟠 High · up to 9ded2

The redesigned Talkies keyboard is likely to crash as soon as it opens, which breaks voice typing. Dictation can also start recording unexpectedly after a user cancels the microphone settings prompt and later grants access. On older Android versions, Android discovery shows only one of several Linux hosts. Fix the keyboard crash and the stale recording action before merging.

Publish a per-machine service name instead of the fixed name Talkies.

Every Linux machine advertises the instance name Talkies. If two machines are on the same LAN, Avahi resolves the name conflict by renaming one of them, for example to Talkies #2. On Android, SshHostDiscovery uses info.serviceName as DiscoveredSshHost.name. NearbyHostCard shows that name, and toProfile stores it as the saved profile name. As a result, users see identical or numbered entries and cannot tell which machine is which. onServiceLost also matches on this name.

Put the machine hostname in the instance name, for example Talkies on <hostname>. Fall back to Talkies if the hostname cannot be read.

Treat the whole 127.0.0.0/8 range and mapped loopback addresses as loopback.

This check excludes only 127.0.0.1 and ::1. A listener on another loopback address passes the check, for example 127.0.1.1:22 (the Debian/Ubuntu hostname mapping) or [::ffff:127.0.0.1]:22. The daemon then advertises an SSH endpoint that the phone cannot reach, and the Android connection attempt fails. The docs promise that Talkies advertises only when "ss reports a non-loopback SSH listener".

Refresh keyboardSelected after the input method picker closes.

showInputMethodPicker() opens a system dialog. That dialog does not pause the activity, so ON_RESUME does not fire after the user picks Talkies. The status is refreshed only on launch and on ON_RESUME. As a result, KeyboardSetupCard keeps "SETUP" and "Choose keyboard" until the user leaves and returns to the activity.

Call refreshKeyboardStatus() from onWindowFocusChanged(true). Another option is to observe Settings.Secure.DEFAULT_INPUT_METHOD with a ContentObserver.

Clear pendingMicrophoneAction when the settings dialog is cancelled or dismissed.

The settings dialog can retain the pending dictation action after the user selects Cancel or dismisses the dialog. If the user later grants microphone permission in Android Settings and returns to Talkies, ON_RESUME invokes that stale action without a new dictation tap.

Keep the current resume behavior for the explicit Open Settings flow. Clear the action only when the user cancels or dismisses the settings dialog, because that flow's text tells the user to return and try again.

Do not treat a dismissed first prompt as a permanent denial.

The user can close the first system prompt with Back or by tapping outside it. In that case, shouldShowRequestPermissionRationale returns false. microphonePermissionAsked is already true because Line 500-501 sets it before the launch. The code then shows "Android has blocked another permission prompt", but Android still allows another prompt.

Store a denial count in permissionPreferences. Show the settings dialog only after a request that follows an earlier denial. Use the stored count together with checkSelfPermission and shouldShowRequestPermissionRationale, as the retrieved learning recommends.

Based on learnings: "persists a 'has requested before' flag ... to correctly distinguish first-run, rationale-needed, and permanently-denied states".

Serialize resolveService calls. Concurrent resolves are dropped silently.

onServiceFound calls manager.resolveService immediately for each service it finds. Before API 34, the legacy NsdManager.resolveService allows only one active resolve. Any other resolve fails with FAILURE_ALREADY_ACTIVE. Discovery usually reports several services in a burst. On a LAN with more than one advertised _ssh._tcp host, every resolve after the first fails. onResolveFailed is a no-op, so those hosts never appear in the list. The app's API 28 baseline includes these Android versions.

Queue the services that are found and resolve them one at a time. Start the next resolve in both onServiceResolved and onResolveFailed. Clear the queue in stop().

Move the current onServiceResolved body into publish(info). In stop(), clear pending and reset resolving.

Serialize NSD resolution in SshHostDiscovery by adding a pending service queue
and resolving one item at a time. Move the current onServiceResolved publication
logic into a publish(info) helper, advance the queue from both onResolveFailed
and onServiceResolved, and have onServiceFound enqueue matching services before
starting resolution. Clear the queue and reset the resolving state in stop().

Give the IME window a lifecycle owner before you attach ComposeView.

ComposeView needs a ViewTreeLifecycleOwner and a ViewTreeSavedStateRegistryOwner on its view tree to create its window recomposer. InputMethodService is not a LifecycleOwner. This class does not set these owners on the input method window. When the keyboard view attaches, ComposeView.onAttachedToWindow should throw IllegalStateException: ViewTreeLifecycleOwner not found. The input method then crashes each time it opens, so Talkies voice typing does not work. Unit tests do not show this failure because they do not attach the view to a window.

Implement LifecycleOwner and SavedStateRegistryOwner in the service. Move the lifecycle through its states in onCreate, onStartInputView, onFinishInputView, and onDestroy. Set both owners on window.window!!.decorView.

🐛 Proposed fix
-class TalkiesInputMethodService : InputMethodService() {
+class TalkiesInputMethodService : InputMethodService(), LifecycleOwner, SavedStateRegistryOwner {
+    private val lifecycleRegistry = LifecycleRegistry(this)
+    private val savedStateController = SavedStateRegistryController.create(this)
+    override val lifecycle: Lifecycle get() = lifecycleRegistry
+    override val savedStateRegistry: SavedStateRegistry get() = savedStateController.savedStateRegistry
override fun onCreate() {
    super.onCreate()
    savedStateController.performRestore(null)
    lifecycleRegistry.handleLifecycleEvent(Lifecycle.Event.ON_CREATE)
    // existing setup...
}

override fun onCreateInputView(): View {
    window.window?.decorView?.let { decor ->
        decor.setViewTreeLifecycleOwner(this)
        decor.setViewTreeSavedStateRegistryOwner(this)
    }
    // existing ComposeView creation...
}
// Send ON_RESUME in onStartInputView, ON_PAUSE in onFinishInputView, and ON_DESTROY in onDestroy.

Update TalkiesInputMethodService to implement LifecycleOwner and
SavedStateRegistryOwner, with LifecycleRegistry and SavedStateRegistryController
initialized and restored in onCreate. Register both owners on
window.window!!.decorView before attaching the ComposeView, and transition
lifecycle state through ON_CREATE, ON_RESUME in onStartInputView, ON_PAUSE in
onFinishInputView, and ON_DESTROY in onDestroy.
