An Android companion app

[KesleyDavid]

An Android companion app

Closes the proposal in #241, and supersedes #349 — that branch was android/core before the last two parity deltas, and it still carried the three pairing security defects those deltas closed.

A native Kotlin + Jetpack Compose client in android/, next to ios/. Same
product, same sidecar, same allowlist — so the companion works from either
phone.

  phone ──LAN / Tailscale / hosted──▶ companion :8810 ──loopback──▶ harness :8799
                                       token, allowlist, Origin refused

server/ is untouched. companion/ is untouched. The only thing this adds
outside android/ is a CI job.

One PR instead of five

#241 proposed splitting this five ways. You said you would rather test the
whole thing than review it piece by piece, so this is one PR. The commits are
still the passes, each one reviewed before it landed, so git log reads as the
five-way split would have.

Parity target

This tracks the iOS app as of upstream 667af71, not upstream main as it moves.
Anything that lands in ios/ after that point is a later Android version, not
a gap in this one. Five parity deltas were ported to reach that point; the last
one closed three security gaps in pairing, which are the three commits below
that touch android/core.

Behaviour mirrors iOS exactly. Visual treatment goes native where Apple has no
counterpart — Material instead of glass and DisclosureGroup, a custom Layout
instead of a Form. The mascot, the Messages-shaped chat, the roster and the
transcript are ports of behaviour, not of painting.

What the phone can and cannot do

The computer still owns agents, keys, transcripts and computers. That is
enforced on this side too, not just assumed:

• No credential reaches disk. The QR credential and the 6-digit code live in
  process memory only; a failed pairing burns them. Only the long-lived token
  persists, in the Keystore-backed store.
• The route you chose is the route it uses. Automatic pairing carries hosted
  HTTPS alone; Tailscale is an explicit choice; a local pin authorizes one exact
  LAN origin. The endpoint list the sidecar returns is availability information,
  not new consent — the phone will not move a bearer to an authority you did not
  pick.
• Provider credentials never come back to the phone, and the phone is never
  asked for an API key. Revoking stays on the computer.
• No foreground service. Notifications arrive while connected; a 25s linger
  window covers ask-and-leave, which is what the iOS session.linger() does.

Tested

1133 JVM tests, 0 failures — 366 in :core, 767 in :app — run with
:core:cleanTest :app:cleanTestDebugUnitTest so the suites genuinely re-execute.
(cleanTest alone does not clean :app:testDebugUnitTest; the task is named
testDebugUnitTest in an application module, so :app:cleanTest quietly
resolves to nothing.)

Every rule added along the way is pinned by a mutation: the production rule is
replaced with the wider version someone would plausibly write, and the intended
test is confirmed to go red. Deleting a rule only proves some test depends on
it; substituting it proves the scope is right. That distinction found six real
defects that were living behind a green suite.

Hardware:

Device	API	What it covered
moto g32 (physical)	33	Pairing over real Wi-Fi, mDNS discovery, runtime permissions at the API 33 boundary, notification shade, approvals, release APK
Emulator	26	minSdk floor, release APK install and first run

Two things worth calling out, because they were found on hardware and not in a
test:

• iOS bug iOS: "Always allow" on a peer-approval card sends deny #312 (a three-option approval card recording deny when you tap
  "Always allow") does not reproduce here — verified on the phone, which
  recorded allow with alwaysAllow: ['ask_bot:<botId>'].
• The notification shade rendered LTR text with RTL paragraph direction under an
  RTL locale. Proven on the device, then fixed. Compose defaults differ from
  TextView here in a way that is easy to miss.

Screenshots

Both devices, on the release build.

First run — Android 8 (API 26), clean install

The first frame explains before it asks. No permission dialog fires here — that was the point of the last pass.	"Not now" leads somewhere useful rather than a dead end, with Settings reachable and the pairing instruction pointing at Settings → Phone.

Pairing — API 26

QR first. "Other ways to connect" starts collapsed, and local discovery — with the network permission it needs — begins only when someone opens it. Before that tap there is not a single NSD line in the log; "Looking…" appears after.

Daily use — moto g32, Android 13 (API 33)

Groups, bots and the mascot. This phone was already paired and upgraded in place — it went straight here, with no welcome screen and no repeat permission prompt.	The transcript: tool calls, an approval card, and a markdown table that reads across rather than down.

What the phone is not allowed to do

Avatar and identity are editable from here; image generation is not, and says why — provider keys cannot be added from a phone.	Settings states what notifications cover and what they do not: closed-app push needs a relay that does not exist yet, rather than implying it works.

The APK

./gradlew :app:assembleRelease writes app-release-unsigned.apk when no key
material is configured, which is the artifact for you to sign with your own key:

apksigner sign --ks <your-keystore>.jks --ks-key-alias <alias> \
  --out app-release.apk app-release-unsigned.apk

It is already zip-aligned, so no zipalign and no jarsigner. android/README.md
has the full flow, including how to have Gradle sign directly if you ever want
that, and why R8 is off (kotlinx.serialization reaches 66 generated serializers
reflectively; a minified build installs and opens and then fails on the first
frame off the socket, so turning it on means writing keep rules and testing
them against a real pairing).

Signing keys never enter this repository; .gitignore refuses *.jks,
*.keystore and *.p12 repo-wide.

Found in your code while porting

Filed rather than worked around, each verified against origin/main before
filing:

• mDNS: cache-flush bit set on shared PTR records and on legacy-unicast replies (RFC 6762 §10.2, §6.7) #467 — mDNS sets the cache-flush bit on shared PTR records, which RFC 6762
  §10.2 forbids; two computers running the companion tend to appear as one.
  Fixed in fix(mdns): keep the cache-flush bit off shared PTRs and legacy replies #471.
• Session.linger(): a stale 25s sleeper can end the next background window early #469 — linger() has no generation token, so a round trip near the end of
  one window can cut the next one short.
• Failover: the trust ratchet does not survive a restart — a superseded local route leads again #479 — the failover trust ratchet does not survive a restart.
• Connected apps: an unreadable credential store makes the phone show every account as disconnected #504 — an unreadable credential store makes the phone show connected
  accounts as disconnected. Shared with the published iOS client.
• Voice: the phone blames ElevenLabs when the configured provider is the system voice #505 — the phone blames ElevenLabs when the configured provider is the
  system voice. Also shared; the Android side follows whatever wording you
  settle on.

Known limits

• Closed-app push does not exist. Notifications arrive while connected, plus
  a 25s linger window for ask-and-leave. A push relay is a separate piece of
  work, and Settings says so rather than implying otherwise.
• No foreground service, deliberately.
• R8 is off, for the reason above.
• Two screen-invocation lines in the pairing flow are covered by source pins
  rather than by a composition test; the rules they invoke are covered. Closing
  them needs Robolectric plus a harness for the public APK, which did not look
  worth it for this release. Recorded rather than claimed closed.
• UNRESOLVED permission state is unreachable from the Android UI, which reads
  authorization synchronously; the rule is pinned in :core instead.
• The API-33 charset overload is guarded by a source scan rather than a test,
  because no JVM test can reproduce that crash — Robolectric does not shadow
  java.*. The scan stands down on its own once minSdk reaches 33.

Estimated code review effort: 5 (Critical) | ~180 minutes

Merge Risk: 🟡 Moderate · up to c608c

The Android companion still has concrete current-head risks: failed token writes may be reported as successful, room data can become stale, compilation may be affected by nullable access, and unreliable tests can hang or fail intermittently. These can cause incorrect pairing state, stale user-visible data, or unreliable CI, so merge should wait for fixes or explicit acceptance.

Preserve the emphasized typography slots. Material 3 1.4.0 defines 15 additional emphasized slots. The public 15-argument Typography.copy call preserves those slots from Typography(), so they retain TextDirection.Unspecified. A Material 3 component that uses an emphasized style can therefore resolve direction from LocalLayoutDirection. Construct Typography with the transformed baseline styles so its emphasized slots inherit them.

Strip only the leading b/ marker in the diff filename.

replace("b/", "") removes every occurrence in the token, not just the git destination marker. For diff --git a/lib/b/build.kt b/lib/b/build.kt the last word is b/lib/b/build.kt, so the card header shows lib/build.kt and drops a path component. Any patch whose path contains a b/ directory shows a wrong filename.

Use removePrefix so only the marker is removed.

Send the trimmed room name, not the raw value.

The guard tests trimmed, then the payload sends value. A name of " Team " reaches the server with its padding. The trim predicate also covers only tab and SPACE_SEPARATOR, so a name of "\n" passes the guard and is sent as a blank name.

Make the recorded stub collections safe for concurrent iteration.

Collections.synchronizedList guards single operations only. It does not guard iteration. healthRequests, pairRequests, and timeoutsFor iterate these lists with filter, while OkHttp threads can still append from another route. The integrated test reads stub.requests at lines 377-390 while the session keeps a live stream open, so an append can overlap a read and throw ConcurrentModificationException.

ChatAvatar drops contentDescription for rooms.

The Chat.BotChat branch forwards contentDescription, and the Chat.RoomChat branch discards it. MausAvatar clears its own semantics, so a room avatar that stands alone gets no accessible name even when the caller supplies one. Apply the same semantics treatment used in BotAvatar (lines 78-82) to the room branch.

Bound the busy-wait so a regression fails instead of hanging.

withTimeout only cancels at a suspension point. The loop body calls Thread.sleep, which never suspends, so the timeout cannot fire. If prepare stops reading before the third chunk, this loop spins forever and the Gradle test task hangs instead of reporting a failure.

Confine the browse-loop state to one thread.

browsing, failure, attempts, started, activeListener, and lockReleased are plain locals. NsdManager.DiscoveryListener callbacks arrive on an NSD-internal handler thread. The API 34 resolve callback arrives on resolveExecutor. Both paths write these locals and call emit().

Two consequences follow. An emitted DiscoveryState can carry a stale browsing or failure, so emptyWhileBrowsing can be wrong on the pairing screen. lockReleased can be read stale by awaitClose while terminal() runs on a callback thread.

resolved is already a ConcurrentHashMap, so only the scalars need protection. Guard every read and write with one monitor, or forward callback events into a Channel and mutate the state only inside the flow coroutine.

Give the scene a teardown that cancels its scope.

The scene creates a CoroutineScope on Dispatchers.Main.immediate and hands it to Session, but nothing cancels it. Robolectric runs every test in the same JVM, so restore, stream, and pairing coroutines from one scene can still be scheduled while a later test drives its own composition. Tests that leave pairSuspendsUntil incomplete keep such a coroutine parked.

Kotlin K2 smart cast safe call equality nullable receiver x?.property == value

💡 Result:

In Kotlin, including under the K2 compiler, the expression x?.property == value involves a safe call and does not trigger a smart cast on the receiver x [1][2]. When you use the safe call operator?., the expression evaluates to null if x is null [3][4]. Consequently, the equality check (==) compares that resulting null (or the result of property access) against value [3]. Because the safe call itself explicitly handles the potential nullability of x, the compiler does not need—and does not attempt—to smart-cast x to a non-nullable type [3][5]. If you require a smart cast on x, you must perform an explicit null check before accessing the property, such as: if (x!= null) { // x is smart-cast to a non-nullable type here if (x.property == value) {... } } This pattern is necessary because the compiler only performs smart casts when it can guarantee that the variable's state remains unchanged between the check and the usage [6][7]. Safe calls are designed to avoid the need for such checks by providing a fallback (null) rather than changing the type of the receiver [3].

site:kotlinlang.org/docs Kotlin 2.2 smart cast x?.property == value nullable receiver

💡 Result:

In Kotlin, a smart cast for a nullable receiver accessed via a safe call (x?.property) does not automatically occur as a result of a direct comparison with a value (e.g., x?.property == value) [1][2]. Smart casting in Kotlin generally requires the compiler to be able to determine that a variable or property is guaranteed to be non-null at a specific point in the code [1][3]. When you use a safe call expression like x?.property, the result of that expression is nullable by definition [2]. The comparison x?.property == value evaluates to a Boolean and does not perform a smart cast on x or the property because the expression itself is not a direct null check or type check of the original variable [1][4][2]. If you need to access the property as non-null, you must perform a standard null check on the receiver x or the property itself before accessing it, which allows the compiler to apply a smart cast [3][4]: // Recommended approach for smart casting if (x!= null && x.property == value) { // x.property is smart-cast to non-nullable here } While the K2 compiler (introduced in Kotlin 2.0.0 and present in 2.2.x) has significantly improved smart casting in various scenarios—such as handling function types and better tracking within try-catch-finally blocks—it does not change the fundamental behavior that a safe call expression result is treated as a nullable value [3][5][6]. If you are working with complex getters, you can use Kotlin contracts to inform the compiler about these relationships, which can enable smart casting when the function returns a specific result [5].

Kotlin compiler "x?.y == value" smart cast receiver

💡 Result:

In Kotlin, a safe call expression (x?.y) does not trigger a smart cast on the receiver (x) even when used in an equality comparison like x?.y == value [1][2]. The compiler's data-flow analysis does not automatically infer that the receiver of a safe call is non-null based solely on the result of an equality check involving the property access [2]. This is because a safe call inherently handles the nullability of the receiver by returning null if the receiver itself is null, rather than proving that the receiver is non-null [3][1]. To achieve a smart cast in such scenarios, you must explicitly eliminate the nullability of the receiver before accessing it [1]. Recommended patterns include: 1. Use a local variable: Assign the nullable property to a local immutable (val) variable, perform a null check, and then access it [4][1]. val temp = x if (temp!= null && temp.y == value) {... } 2. Use standard library functions: Functions like let, also, or run can scope the non-null value for you [1]. x?.let { if (it.y == value) {... } } 3. Use the Elvis operator for early return: If the context allows, return early if the value is null, which informs the compiler that any subsequent code operates on a non-null value [1]. val temp = x?: return if (temp.y == value) {... } These approaches work because they establish a stable, non-null reference that the Kotlin compiler can safely track for smart casts [1][5].

Check the result of commit() in save.

SharedPreferences.Editor.commit() returns false when the write does not land, and it does not throw. save discards that result, so a failed write returns as success. Session.pair then makes the connection restorable, which produces the exact state the class documentation says this ordering prevents: a restorable pairing whose token never landed.

Throw TokenStoreException when commit() returns false.

     override suspend fun save(connectionId: String, token: String) {

Kotlin documentation import aliases Java static method overload resolution URLEncoder encode Charset

💡 Result:

When calling Java static methods from Kotlin, such as java.net.URLEncoder.encode, overload resolution is governed by Kotlin's standard overload resolution rules [1]. In the specific case of URLEncoder.encode, Java provides two primary overloads: one accepting a String (encoding name) and one accepting a Charset [2][3]. Kotlin generally resolves these correctly if the argument types are distinct [1]. If you encounter ambiguity—which can occur with certain primitive versus object types or if the compiler cannot automatically disambiguate—you can resolve it by: 1. Explicitly specifying types for arguments to ensure the correct overload is selected. 2. Using fully qualified names or explicit imports to ensure the correct method is targeted. 3. Defining an import alias if necessary to clarify or simplify access, though this does not change the overload resolution process itself [4]. For example, import java.net.URLEncoder.encode as urlEncode allows you to refer to the method by the alias urlEncode [4]. When dealing with URLEncoder.encode(String, Charset), ensure the second argument is an instance of java.nio.charset.Charset (e.g., java.nio.charset.StandardCharsets.UTF_8). If you pass a String, Kotlin will select the encode(String, String) overload. If you explicitly pass a Charset object, Kotlin will resolve to the encode(String, Charset) overload [2][3]. If you face persistent "overload resolution ambiguity" (often seen with primitives and boxed types in Java interop), a common workaround is to create a small Kotlin wrapper or helper function that explicitly calls the desired overload [5]. Import aliases are primarily useful for renaming or avoiding naming conflicts, rather than altering how the compiler chooses between overloaded Java methods [4].

Detect aliases of URLEncoder and URLDecoder.

charsetCalls matches only the literal type names. An aliased type or member import can hide a Charset overload call, allowing it to pass the source pin. Resolve aliases before matching, or reject aliases and direct member imports. Add these cases to assertRefused.
