v0.3.0

Added

  • Setup Profile backup & restore — export your current setup (storage root, picked emulators, dual-screen and GPU-driver flags) to a small JSON file, then import it on a new device to skip the setup flow. Found at the new Profile screen.
  • BIOS file validation in Health Check — the Health screen now inspects actual BIOS files (not just folders), reports which files are missing, and checks hashes against publicly documented reference values. Only systems the user plausibly configured are checked to avoid false-positive warnings.
  • Catalog source check in Health Check — a new Health check probes a sample of emulator entries against their download sources, catching dead links early before a setup run hits them.
  • Per-emulator GPU driver hints on Dashboard — Adreno-device users see a one-line hint on each emulator card indicating the recommended driver.
  • Catalog "what's new" banner — a dismissible banner on the Dashboard surfaces newly added or updated emulator entries after a manifest refresh.
  • Show/hide toggle on GitHub token field — the token entry in the About screen is now masked by default with a visibility toggle, matching standard password-field conventions.

Changed

  • Package-manager scan on Dashboard and Picker screens moved fully off the main thread; emuHelperInstalled is now a StateFlow rather than a blocking PM call in composition.
  • Rapid successive refresh calls (e.g. after Update All completes) are debounced so only one reload fires instead of one per completed update.
  • Update check writes all results in a single DataStore transaction instead of one per entry, eliminating redundant re-decode on every write.
  • Health Check checks now run with bounded concurrency (semaphore-guarded async/awaitAll) for faster overall completion.
  • Foreground service uses SupervisorJob; tapping the progress notification navigates back to the app.
  • Cancelling a setup run now immediately stops the foreground service and dismisses the notification (previously the notification could linger).
  • The Test Install debug screen has been removed.
  • GitHub token store uses an eagerly-started StateFlow so the first API call on launch is authenticated even before any subscriber exists.
  • Picker card toggle switched from clickable to toggleable with Role.Checkbox; GPU driver opt-in card on the Shizuku screen similarly updated for correct TalkBack semantics.
  • Hardened internals and expanded test coverage (SHA-256 sidecar parsing, manifest diff store, health checks, update paths).

Fixed

  • Profile Import hang — importing a profile no longer freezes the UI; file reading is dispatched to IO, and the ViewModel guards against re-entrant invocations.
  • Android 10 crash — AllFilesAccess now gates Environment.isExternalStorageManager() and ACTION_MANAGE_APP_ALL_FILES_ACCESS_PERMISSION behind an API 30 check; on Android 10 (API 29) it falls back to WRITE_EXTERNAL_STORAGE, fixing a NoSuchMethodError / ActivityNotFoundException crash at the permissions screen.
  • Health Check Back button now shows the D-pad focus ring when navigated to with a controller.
  • Picker app list sorted inside remember so the sort does not re-run on every recomposition; installed-count also memoised.
  • confirmOffline no longer tries to complete an already-cancelled deferred, which could silently swallow the cancel.
  • Uninstall flow no longer triggers a full PM scan; uses the cached registry snapshot instead.
  • updateAll() is now mutex-guarded, preventing a double-tap from launching two concurrent update sequences.

Security

  • Update All / Update One now verify APK integrity. The dashboard update path previously passed null as the expected SHA-256, installing downloaded APKs without an integrity check. It now fetches the SHA-256 sidecar (when published by the source) and aborts with an error if the fetch fails — matching the behaviour already enforced on the initial setup path.
  • Profile import caps file reads at 256 KB and validates the imported storageRoot against the device's real mounted volumes before prompting the user to adopt it, blocking path-traversal and sandbox-escape attempts via a crafted profile file.
  • Profile import schema-version gate rejects files produced by a newer version of EmuTran rather than silently mis-applying unknown fields.

Install: download EmuTran-v0.3.0.apk below and open it on your device. Existing users on v0.2.0 will be offered this update in-app (verified against the SHA-256 sidecar before install).
