[v2.0.0] 2026-05-22

This is a major release representing a complete overhaul of the SENDA codebase
and a significant expansion of features since v1.3.0.

Breaking changes

  • The app has been fully rewritten in Kotlin (previously Java). The minimum
    supported Android version remains Android 11.
  • The internal package structure was reorganised for improved modularity.

New features

  • Dark theme support (follows system setting).
  • In-app tutorial with multiple pages guiding new users through setup.
  • About dialog accessible from the action bar.
  • Movella DOT sensor support: connects once on discovery to resolve the
    human-readable name, then reconnects for measurement.

Improvements & refactoring

  • Migrated to MVVM architecture with ViewModel and Repository pattern.
  • Foreground service and wakelock handling refactored for targetSdk 34+.
  • Permissions handling streamlined; new transient starting / stopping
    UI states provide clearer feedback.
  • 16 KB ELF page-size compatibility: native code compiled with the required
    alignment flags (Google Play requirement since November 2025). Note that the
    bundled Movella SDK library is not yet compatible.
  • Main layout simplified to LinearLayout; old landscape / splash layouts and
    unused preference XMLs removed.
  • compileSdk / targetSdk raised to 35; NDK updated to r28.
  • Gradle plugin updated to 8.1.2 / 8.10; setup-gradle action bumped; CI
    workflow split into separate debug and release APK jobs.
  • LSL service start/stop made concurrency-safe.
  • LocationBridge crash on startup fixed.
  • MainActivity crash fixed by lazy-initialising the ViewModel.
  • Sensor outlet race condition fixed (sensor stream now starts only after the
    LSL outlet is initialised).
  • Unit test added for MainViewModel.
  • App correctly stops the foreground service when swiped away from recents.

UI / UX

  • Stream availability status text updated.
  • Layout margins adjusted in activity_main.xml.
  • Settings/gear menu icon removed (no configurable settings at this time).
  • Tutorial layout constraints and text corrected.

Build & CI

  • APK signed correctly via GitHub Actions using repository secrets.
  • Separate CI jobs for debug builds (feature branches) and signed release APKs
    (master branch).
  • Signing configuration now checks for keystore existence before applying
    settings, preventing local-build failures.
