# Android architecture decision
Accepted implementation contract for [#88](https://git.rfc1437.de/hugo/IronStorage/issues/88)
in milestone 23, **06 - Implement an Android version of the software**.
Reviewed against the checkout's iPhone app, AutoFill extension, and shared Rust
mobile APIs on 2026-10-08. The milestone goal is full native Android feature
parity. This decision records ownership and release requirements; it does not
claim that the Android implementation or device audit already exists.
## Language and presentation
Use Kotlin, Gradle Kotlin DSL, one activity, Jetpack Compose, Material 3 and
Material 3 Adaptive. Use Navigation 3: its [stable release is 1.2.0](https://developer.android.com/jetpack/androidx/releases/navigation3).
Screen ViewModels expose immutable StateFlow state and accept typed events.
Compose observes with collectAsStateWithLifecycle. Hilt supplies dependencies;
KSP runs its processors. Blocking UniFFI calls run on a bounded background
coroutine dispatcher. Cancellation cancels the Rust operation as well as the
coroutine; a late result must not restore a revoked lease or stale screen.
Rust owns repository layout, config, keys, OpenPGP, Git, conflicts, documents,
generation, OTP, QR payloads, identities, external access permissions and
secure-secret orchestration. Kotlin collects input, renders Rust state, and
adapts OS mechanics. No app component launches a subprocess. No Kotlin feature
reads repository files, parses entries/URIs or error labels, generates passwords
or codes, or independently decides credential matches or authentication policy.
Use typed semantic icons/actions, stable IDs, generation/revision tokens,
view-ready records and typed errors. #91 removes SF Symbol and Watch assumptions
from shared phone contracts. Keep Swift compatibility through mechanical
adapters. #92 generates Kotlin and Swift from one shared UniFFI surface rather
than copying crates/apple conversions. A thin Android bridge may adapt platform
callbacks; it must contain no password-store decisions or handwritten unsafe
Rust. Generated/dependency FFI stays isolated from project-authored safe Rust.
## Modules and allowed dependencies
| Module | Responsibility | Allowed project dependencies |
| --- | --- | --- |
| android/app | Activity, composition root, navigation, manifest and service registration | features, core, platform |
| android/features | Related Compose workflows, screen ViewModels, accessibility | core only |
| android/core | Android-facing facade, immutable presentation contracts, coroutine scheduling, bridge mapping | rust-bridge |
| android/platform | Keystore, BiometricPrompt, clipboard, camera, paths and OS request translation | core contracts |
| android/rust-bridge | Generated UniFFI Kotlin and ABI native packaging | shared Rust bridge via build tasks |
| Shared Rust bridge | Mechanical records, lifetime/callback/error conversion | crates/storage |
| crates/storage | All domain behavior and trust-boundary validation | audited Rust dependencies |
Start with these five Gradle modules; split feature groups only when useful.
Platform implementations are injected at app composition. Feature code cannot
import generated UniFFI/JNA types or depend directly on platform/bridge modules.
OS services delegate to core; exported service input is untrusted. Only Rust
holds repository capabilities. Gradle dependency checks, source-boundary checks,
and release manifest inspection are gates in #89/#94/#111, not substitutes for
review. Generated bindings and native/build outputs are not checked in.
## Support and build policy
Production package, namespace and application ID: **de.rfc1437.ironstorage**.
Updates retain this ID and signing lineage. Tests use derived IDs; a development
variant may not masquerade as the production signed installation.
Minimum SDK: **26** (Android 8, including Autofill). Compile/target SDK: **37**
(Android 17) at this decision, following the [SDK instructions](https://developer.android.com/about/versions/17/setup-sdk).
Recheck stable SDK and [Play requirements](https://support.google.com/googleplay/android-developer/answer/11926878)
at implementation and release. Never select preview APIs to satisfy a release
policy. The installed android-37.0 SDK reports an empty codename and
PreviewSdkInt=0 (revision 2); verify the same package metadata in CI before
pinning the build, rather than relying on preview wording in older instructions.
Release ABIs: **arm64-v8a**, **armeabi-v7a**, **x86_64**, corresponding to
**aarch64-linux-android**, **armv7-linux-androideabi**,
**x86_64-linux-android**. An ABI may be removed only with a dependency audit and
an amendment to this decision; emulator success alone proves no arm64 hardware
coverage. All shipped native dependencies, including JNA, must pass ELF LOAD
alignment, APK ZIP alignment and actual 16 KB runtime checks. Do not depend on
compatibility mode. [Android's page-size guidance](https://developer.android.com/guide/practices/page-sizes)
requires auditing dependencies as well as the app library.
At #89 pin a mutually supported stable AGP/Gradle/Kotlin/KSP/Hilt set, JDK,
SDK build tools and NDK, plus wrapper checksum. The current [AGP 9.4 contract](https://developer.android.com/build/releases/agp-9-4-0-release-notes)
requires Gradle 9.6.0 and JDK 17 and supports API 37. This is a candidate build
baseline, subject to actual artifact availability and plugin compatibility.
No dynamic versions, snapshots or automatic toolchain substitutions. #92 pins
cargo-ndk, Rust targets/toolchain and the workspace UniFFI version and builds all
ABIs from the locked Cargo graph. Retain separate native symbols and R8 mappings.
Support phones, tablets, foldables, resizing/multi-window, desktop windowing,
portrait/landscape, system/light/dark themes, hardware keyboard, large fonts,
TalkBack and process recreation. Preserve non-secret navigation/filter state;
never serialize decrypted fields, passphrases, tokens, QR key payloads or a lease
into SavedStateHandle, bundles, preferences, crash reports or test artifacts.
Rotation/process death must not replay a mutation. In-flight mutations resolve
through Rust revision/transaction state before a retry.
Apple Watch, watchOS and Watch Connectivity are excluded. Android Auto, TV,
Wear OS and XR-specific experiences are outside the product; Wear is not a
substitute for Watch. Do not show disabled Watch controls on Android.
## Approved dependencies and review policy
These are approved purposes, not permission to add every library immediately.
#89 pins only scaffold dependencies; later owners add their required artifacts.
Exact versions live in one version catalog, Cargo.lock and reviewed toolchain
pins. Keep Gradle dependency verification metadata and locks where supported;
review checksums independently before accepting a new artifact. For each addition
and upgrade, record exact coordinates/version, upstream release/maintenance
check, SPDX license and bundled notices, transitives, security advisories and
compatibility results. Approval of a library family does not approve every
transitive version. #94 builds the resolved SBOM/license gate; #112 bundles
attributions and available source obligations.

| Android framework | Keystore, KeyguardManager, AutofillService, clipboard, FLAG_SECURE, private paths, backup rules, connectivity and permissions | OS APIs; no extra bundled crypto/storage implementation; behavior audited on supported APIs/OEMs |
DataStore is allowed only for presentation-only preferences if necessary.
Shared preferences use Rust configuration. Room, Retrofit/OkHttp, JGit,
Bouncy Castle/OpenPGP, Kotlin OTP/password/parser libraries, ML Kit payload
interpretation and a competing QR format are prohibited. Reuse existing Rust
crypto/Git/QR code. Do not schedule interactive unlock, secret display or repository
mutations as background WorkManager tasks.
## Threat model and state lifetime
Protect the pass repository/key material, passphrases, HTTPS application tokens,
OTP secrets/codes, decrypted fields, credential selections and identity grants.
Untrusted inputs include remote endpoints/data, repository entries and policies,
QR/images, OS provider callers, restored files, and concurrent/stale UI requests.
Rust validates transports before any repository mutation or connection and uses
repository remotes as authoritative. Android starts HTTPS-only with SSH disabled;
SSH endpoints still parse to typed unsupported errors. Adding SSH requires an
explicit audited support decision while preserving storage-owned transport policy.
The sandbox and Keystore protect against ordinary cross-app access and accidental
backup, not a fully compromised/rooted device. Debuggable builds, logs, screenshots,
recents thumbnails, clipboard history, accessibility, keyboard suggestions and
crash telemetry are disclosure paths. #100 uses FLAG_SECURE, redaction, background
relock, bounded clipboard ownership/expiry and memory cleanup; never claim complete
Kotlin/JVM memory erasure. Clear platform references and revoke Rust generations.
Keystore holds non-exportable AES-GCM wrapping keys. Only sealed envelopes reach
private storage. Rust decides secret type, identity, enrollment/invalidation,
authentication policy, lease and recovery. Kotlin translates OS error facts.
BiometricPrompt authorizes the required CryptoObject; device credential fallback
must match the Rust policy/API level and must not silently weaken it. Changed
biometrics, lock-screen removal, restored-without-key data, cancellation and a
stale callback fail closed and require explicit recovery. Provider candidates
are non-secret until authorized user/system selection plus a valid lease.
## Paths, backup, update and recovery
#90 receives canonical filesDir, noBackupFilesDir and cacheDir from Android once;
Rust creates scoped capabilities and owns all contents. Never infer HOME or use
public/shared storage. Place repository, keys, config, TOTP discovery catalog,
Keystore envelopes and transactional durable scratch under noBackupFilesDir.
Disposable camera/image buffers may use cacheDir only when cleanup is safe;
never use the cache for the only copy of a repository or credential.
Set allowBackup=false and explicit legacy backup and Android 12+ data-extraction
rules excluding all sensitive roots from cloud backup and device transfer. Test
OEM transfer behavior; no claim that one manifest flag defeats every OEM tool.
No automatic key/repository transfer. The TOTP catalog contains only canonical
path, ciphertext SHA-256 and is_totp; treat even that metadata as private.
An APK/Play update installs over the same ID/signing lineage and retains valid
private state and Keystore aliases. Migrations are Rust-owned, versioned and
atomic; migration failure retains prior recoverable data. Process death revokes
in-memory authentication, preserves valid completed cache checkpoints and leaves
atomic transactions recoverable. Low storage/read-only/corruption produce typed
errors without deleting unrelated data. Uninstall/reset deletes app data and can
make keys unrecoverable; reinstall/restore is not an update. Recovery needs the
user's externally retained encrypted key material/passphrase and, when configured,
a remote clone. Do not seed app data or commit credentials to prove recovery.
## Verification and acceptance
The [parity matrix](parity.md) assigns every current non-Watch mobile capability
and every Android issue to a Rust owner and Android API. Its pending rows are
implementation obligations, not accepted gaps. #111 must replace pending status
with evidence and have no unexplained gap before #112 distribution.
Every issue runs the AGENTS.md Rust gates before commit. Android changes also
run build/lint/unit/instrumented checks appropriate to the issue and computer-use
validation on the existing emulator. Update by installation over the existing
app, never uninstall/reset. If unlocking needs an unavailable user, label the
issue untested and document exactly what could not be checked. Emulator evidence
cannot satisfy physical biometric/camera/Keystore/autofill or Play acceptance.
Apple changes require XcodeGen and affected simulator builds and UI checks;
never re-enroll an already enrolled iPhone simulator in ordinary validation.
#94 owns reproducible CI and test boundaries, #105 accessibility/performance,
#111 the complete architecture/security/parity audit, and #112 physical production
install/update/Play release evidence. No release approval is implied by this ADR.

# Android parity and issue ownership
Contract for [#88](https://git.rfc1437.de/hugo/IronStorage/issues/88), reviewed
2026-10-08 against apple/Sources/App/IronStorageApp.swift,
apple/Sources/AutoFill/CredentialProviderViewController.swift, crates/apple/src/lib.rs,
and crates/storage/src/mobile*.rs. See [architecture.md](architecture.md) for
support, dependency, security and update policy.
**Status:** all Android implementation rows below are pending. No Android app
exists at this decision. The table is a complete assignment of work, not a
claim of completed parity. #111 must attach screen/component/test evidence to
each row. Every issue linked here belongs to milestone 23.
## Current iPhone and shared-mobile capabilities
| Existing capability / source | Owning Rust API/module | Android presentation / approved API | Implementation and required evidence |
| --- | --- | --- | --- |

| Key identity/fingerprint, GPG recovery import and public/private QR export (KeyImportScannerViewController, KeyExportListViewController, KeyQrExportViewController) | mobile_key_transfer::{MobileKeyTransferService,MobileKeyTransferImport}; crypto/presentation | CameraX Preview/ImageAnalysis; animated Rust-provided matrices | #106/#104; multi-frame order/duplicates/interruption, bounded frames, private export authorization and camera denial |
| Inactivity timeout, biometric enable/disable, Lock Now, appearance and Git commit name/email | mobile_authentication preference setters, git_identity; config | Compose Settings, BiometricPrompt, system/light/dark theme | #98/#104; persistent settings, validation, Keystore enrollment/recovery and lease revocation |
| iPhone AutoFill credential selection (CredentialProviderViewController) and shared identity/access domain | desktop/read/document/secret_store today; storage-owned provider contract to add | AndroidX CredentialProviderService (API 34+) and framework AutofillService (API 26+) | #109; typed caller/site identity, non-secret candidates, explicit selection/auth, forged/stale requests, permissions and cross-process lifetime |

| Watch pairing/install state in Settings; TOTP Watch selection, snapshots, receipts, transfer and watchOS detail | mobile_watch; Watch fields currently in mobile_totp/mobile_authentication and Apple bridge | Excluded from Android records and UI by #91 | Deliberate Watch-only exclusion; no unsupported placeholder controls or Wear implementation |
Name search matches current mobile behavior; CLI/TUI decrypted grep is not an
iPhone parity claim. Android has no separate filesystem-based search. The
shared core's recipient/signing rules, pass/pass-otp format, HOTP counter safety,
Git failure semantics and secret-redaction requirements remain binding wherever
an Android workflow invokes them; platform presentation may not replace them.
Current iPhone camera adapters pass OS-decoded QR bytes. Android #106/#91 must
also supply bounded image/frame facts for Rust decoding as required by the
Android contract; that additional adapter is pending, not an existing API.
The external-credential matching/grant API required by #109 must be implemented
in storage, rather than copying frontend selection assumptions from AutoFill.

#87 is the closed umbrella issue, not an open implementation candidate. Verify
live issues after each closure; newly created bug/critical issues may change the
order. #91 and #90 currently name later packaging/contract dependencies; their
implementations may establish the necessary narrow Rust APIs before consuming
full Android packaging, but they must meet all stated acceptance tests before
closure. Do not close a partly integrated issue just because its unit tests pass.
