Android ART Optimizer 0.2.1

A permanent APK download URL for AFTVnews Downloader and other direct installation tools, plus the dependency and build-tool updates merged since v0.2.0.

What changed

  • Each release now provides identical signed APKs as android-art-optimizer-v0.2.1.apk and android-art-optimizer.apk. Both are covered by SHA256SUMS.txt.
  • The permanent latest APK URL uses GitHub's latest published production release. Future releases require no change to this URL or a Downloader code created for it.
  • The release workflow downloads and verifies both uploaded APKs before publishing, then verifies the permanent URL without authentication when GitHub selects the new release as latest.
  • The README documents direct downloading and public repository access. Versioning, signing, source packaging, and GitHub's release-selection behavior are preserved.
  • Includes Android Gradle Plugin 9.4.1, Gradle 9.8.0, Compose compiler plugin 2.4.20, Compose BOM 2026.09.00, and ZXing 3.5.4, with updated dependency/license records.
  • Includes GitHub Actions updates for checkout v7, Java setup v6, artifact upload v7, and Gradle setup v6 using basic caching.

Newly included merged maintenance PRs: #2, #3, #4, #6, #7, #9, #11, #12, #13, alongside the permanent-download change in #17. Previously released Ethernet ADB and v1 features remain included.

Install or update

Download android-art-optimizer.apk or android-art-optimizer-v0.2.1.apk; they are the same APK. Android 11+ is required. The app supports phones, tablets, and compatible Android/Google TVs, using runtime capability detection.

Official v0.1.0/v0.2.0 installations can update in place with the same production signing certificate. Debug/test builds use a different certificate: note your configured package IDs, uninstall the test build, install the official APK, and authorize/pair again. Uninstalling removes the test build's local data; the release does not uninstall anything automatically.

After this release is published and the permanent URL is verified, a numeric Downloader code can be generated through AFTVnews and added to the README. That documentation-only update needs no additional app release. The code must target the permanent URL rather than a version-specific asset.

Validation and limits

Lint, 31 JVM tests, debug APK assembly, signed release candidate assembly, and 12 release-helper regression tests pass. Workflow validation covers YAML syntax and GitHub Actions semantics. Offline workflow tests verify identical stable/versioned APKs, upload/download checksums, draft reruns, published-release protection, and the permanent download check.

The current debug candidate was installed in place on the TCL C765 (firmware reports TCL Smart TV Pro/G08), Android 14. Shared preferences were preserved exactly during installation, and startup showed Connected over Ethernet with verified device identity. The user reported that the app works. This is debug-build device validation; the downloaded production APK's signature, version, checksums, source archive, and permanent URL are verified separately during publication. This release retains the existing connection and optimizer behavior; the broader device limitations remain in the test plan.

The release includes both signed APK filenames, SHA256SUMS.txt, and the source ZIP with the exact tagged application source and pinned dependency sources. Only one APK is needed for installation.
