Closes #888

Summary

The foreground session service and the microphone permission plugin (Kotlin, manifest entries, strings, lifecycle-process) now ship in the new crate crates/tauri-plugin-android-host with its own Android library module (dev.smartssh.androidhost). app-shell uses its two constructors (session_service(), microphone()); the community app lists the crate as a direct Android dependency and loses the moved files, manifest lines and strings. The notification icon is now the host app's icon at runtime (applicationInfo.icon).

Acceptance Criteria

• Crate with build.rs, android/ library, three Kotlin classes, manifest, strings: met (crates/tauri-plugin-android-host).
• App tree contains only MainActivity.kt; app manifest has no moved entries: met.
• Merged APK manifest keeps all entries; scripts/check-android-apk-manifest.sh runs in android-build: met in code; verified in CI on the built APK (job Android debug APK green) and locally against a stubbed aapt dump (pass and fail case).
• tauri.settings.gradle lists the library (CI step): met (same CI step, green).
• Existing Android CI job incl. emulator smoke test: met (both green).
• Desktop cargo clippy -p app-shell -p tauri-plugin-android-host --all-targets -D warnings: met (the desktop unit test was dropped: a test binary linking Tauri cannot start on the Windows runner); cargo check -p app-shell --target aarch64-linux-android compiles.
• Docs, ADR 0154, Spec 0114 §4: met.
• Manual device check: needs manual check on Android (below).

Tests

Desktop unit test tauri-plugin-android-host/src/lib.rs:plugins_are_named_and_build_on_desktop. No regression test applies (refactoring); no full gate run locally.

Assumptions

• Two plugin constructors, as recommended in the issue.
• The crate is an Android-only direct dependency of the app (it is a no-op elsewhere); app-shell depends on it unconditionally.
• Library minSdk 26 and compileSdk 36 as in the app. Intent action strings now use the library namespace prefix (internal).

CI changes

• .github/workflows/community.yml, job android-build, new step after the 16 KB alignment check: greps tauri.settings.gradle for the library and runs scripts/check-android-apk-manifest.sh on each built APK. No new actions, secrets or permissions.

Spec

updated 0114 (§4)

Threat model: no change – same permissions and service, only the packaging of the Kotlin code moves.

Manual test steps

1. Install the debug APK on a device/emulator, open a session, background the app: notification with "Disconnect all" appears with the app's icon.
2. Start voice input: the microphone permission prompt appears.

Follow-ups

None.

Review

Verdict: approved
Review level: normal

Blocking

None.

Non-blocking

• crates/tauri-plugin-android-host/src/lib.rs:1 — the doc comment cites "ADR 0153", but the new ADR is 0154 (0153 is the entitlement ADR). Cosmetic.
• PR body "Tests" names plugins_are_named_and_build_on_desktop, but the crate has no test (the Summary says it was dropped). Refactoring only, so no regression test is required.

Verified

• counter-proof: not applicable, because this is a packaging refactoring with no behaviour fix
• edge cases: microphone plugin still registered in the after-unlock chain via microphone_plugin() (read: lib.rs:1129,1157) → ok; non-Android builds get empty plugins → ok; session_service handle missing is handled via try_state (read: android_service.rs) → ok; all R.* references in the Kotlin files resolve to the library's own package and strings (executed: rg) → ok
• callers checked: voice_input::microphone_plugin removed (no remaining references), Handle/SessionServiceHandle (2 call sites) → ok
• tests run locally: cargo clippy --locked -p tauri-plugin-android-host -p app-shell --all-targets -- -D warnings → clean (executed). The crate has no tests; the aarch64-linux-android check was not run locally (toolchain not available), covered by CI instead.
• CI: all checks green, including Android debug APK (with the new manifest/Gradle step) and the launch smoke test (executed: gh pr checks 990)
• read: all moved Kotlin files (diff), manifest, strings, build.gradle.kts, scripts/check-android-apk-manifest.sh, workflow step
• files read: 5/5 logic files
• UI: not a UI change
• data: not touched

Timing analysis

• no test files changed

Spec

• visible behaviour changed: none (notification shows the host app's icon, same app icon as before)
• spec searched (terms: Hintergrund, foreground, Mikrofon, android), spec covering it: 0114 §4, which the PR updates
• verdict: spec change present and matches the code

Security checks

• Permissions, service entry and foregroundServiceType unchanged; the service only reflects the session count. The CI step only greps and runs aapt; no new actions, secrets or permissions. No filter/risk/redaction/credential code touched. Threat model: no change is justified. Assigned security-paths.txt paths are not touched.

Manual checks pending

• Notification with "Disconnect all" and the app icon after backgrounding with an open session; microphone permission prompt on voice input (Android device or emulator)

Follow-ups

None.

None.

Non-blocking

• Carried over from the previous review: the doc comment in crates/tauri-plugin-android-host/src/lib.rs cites ADR 0153, but the new ADR is 0154. The PR body names a desktop test that was dropped. Both are cosmetic.

Verified

• follow-up round: the only change since the approved commit a8f83d8 is a merge of develop. The PR's own files (plugin crate, app-shell android files, manifest check script, Spec 0114) have an identical diff against the merge base before and after (executed: git diff + sha1sum).
• CI on the new head: all checks green, including Android debug APK, the launch smoke test, and tests on all three OSes (executed: gh pr checks 990).
• ADR number 0154 is unique on the base branch, and no other open PR touches it (executed: ls, gh pr list).
• tests run locally: none. The Rust toolchain could not be installed in this container (permission denied), so I relied on CI.
• counter-proof, UI, data: not applicable (packaging refactoring).

Timing analysis

• no test files changed

Spec

• visible behaviour changed: none
• spec searched earlier (terms: Hintergrund, foreground, Mikrofon, android); covering spec 0114 §4, updated in the PR
• verdict: spec change present and matches the code

Security checks

• Unchanged since the previous review. Permissions and service entry are unchanged, and no security-critical paths are touched.

Manual checks pending

• Notification with "Disconnect all" and the app icon after backgrounding with an open session; microphone permission prompt on voice input (Android device or emulator)

Follow-ups

None.
