TV AutoBuild

Automated release pipeline for customized Mobile and Leanback APKs with AV3A, Dolby Vision, HEVC-FLV, and real-time AI subtitle support.

APK variants

Each successful build publishes four release APKs:

• TV-mobile-arm64-v8a.apk
• TV-mobile-armeabi-v7a.apk
• TV-leanback-arm64-v8a.apk
• TV-leanback-armeabi-v7a.apk

Build behavior

• Checks for updates every 15 minutes.
• Builds only when monitored inputs change, unless a build is forced manually.
• Builds the speech-recognition and AV3A JNI runtimes from source for both supported ABIs.
• Runs Mobile and Leanback unit tests before packaging.
• Applies R8 optimization to release APKs.
• Verifies APK signatures before publishing.
• Publishes build metadata, exact input revisions, and SHA-256 checksums with every release.

GitHub scheduled workflows can be delayed. Use Actions → Monitor sources and build APKs → Run workflow for an immediate manual build.

Versioning

Each build receives a monotonically increasing Android versionCode and a traceable version name:

<base-version>-autobuild.<run>+<revision>

This allows newer builds of the same variant to update earlier AutoBuild installations while retaining traceability.

Signing

All APKs are signed with a persistent dedicated release key stored in GitHub Actions secrets. The private key and passwords are never committed.

The public signing certificate is available as autobuild-signing-cert.pem. Its SHA-256 certificate fingerprint is:

17:8A:B4:F2:5C:CC:E5:BC:B4:FA:7A:9D:38:B6:7C:7E:1F:3C:54:D2:56:D0:D2:CB:A0:6C:6E:FE:A7:10:A4:AB
