Problem

I install T3 Code through Obtainium from the GitHub releases. Every update, and nightlies come often, is a ~280 MB download. Most of it is native code for CPU architectures my phone doesn't use. The GitHub APK is Play's universal APK, which stores native libraries uncompressed for all four ABIs (about 235 MB of the 281 MB in 2.1.0-434).

Change

The mirror script also downloads Play's signed split APKs from the same generatedApks response and publishes one .apks zip per ABI next to the universal APK. Each zip holds the base, that ABI's split, and every density and language split from the lowest-SDK variant. Zipping compresses the native code, so an arm64 set should be around 50 MB.

• The signature is Play's, so updates still work between Play and GitHub installs.
• The universal APK is unchanged, for people who just tap to install.
• Obtainium matches ABI names in file names, so it will offer the matching .apks by default. The base APK in the zip is named after the package because Obtainium installs the file with that prefix first.
• If the split targeting can't be read, the script logs a warning and publishes the universal APK alone.
• Releases get about 4 extra files (~200 MB total).

Scope and approval

No prior discussion. It only changes what the existing APK mirror uploads, and Play builds and signing are untouched. Happy to move it to a discussion if you'd rather.

Verification

• New unit tests for picking the split pieces (node --test .github/scripts/mirror-play-apk.test.cjs), added to the CI "Test release checks" step.
• Ran the full script against a mocked Play API and a stubbed gh: the nightly path writes the APK plus four .apks to APK_OUTPUT_DIR, and the beta path creates one release with all five files.
• Not checked: a real run against Play (needs the Play credentials), and an Obtainium install of a real set. The ~50 MB figure is an estimate from compressing the pieces of the 281 MB APK.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — This PR adds automatically generated per-architecture split APK archives to the Android mirror and release pipeline, including new Play downloads, packaging, and published artifacts. The capability is user-facing and changes an existing release path, so its release behavior and artifact compatibility warrant human review.

Walkthrough

The Android APK mirror now prepares architecture-specific .apks archives from Play-generated splits and publishes or copies them alongside the universal APK. Release workflows, CI checks, the mirror job timeout, and release documentation are updated.

Changes: Android APK mirror

Layer / File(s)	Summary
Plan split APK sets .github/scripts/mirror-play-apk.cjs, .github/scripts/mirror-play-apk.test.cjs, .github/workflows/ci.yml	The script plans install-time split sets from the lowest-SDK variant and groups them by ABI. Tests cover set contents, excluded on-demand modules, missing data, and invalid APK references. CI runs the new tests.
Download and stage APK assets .github/scripts/mirror-play-apk.cjs, .github/workflows/mobile-android-apk.yml	The script downloads selected APKs, packages split sets as .apks archives, and stages all assets for local output or beta publication. The mirror job timeout increases to 20 minutes.
Integrate assets with release workflows .github/scripts/mirror-play-apk.cjs, .github/workflows/release.yml, docs/operations/release.md	Release checks determine whether each expected asset is uploaded and nonempty. Release collection and documentation include .apks files.

Review comments at @.github/scripts/mirror-play-apk.cjs:
- Around line 168-193: Treat split-set downloads and ZIP creation as best
effort: wrap the splitSets processing in error handling that warns and returns
only the existing universal APK assets if any download or zip operation fails.
Stage set paths separately and add them to assets only after their zip calls
succeed, so failed builds never publish partial split archives.
- Around line 209-214: Update publishBeta to upload only asset paths whose
matching release assets are absent, empty, or not in the uploaded state; leave
valid uploaded assets untouched. Pass this filtered list to gh release upload
and skip the upload call when the list is empty.

closing at @StiensWout's request under Establish the problem and scope first.

Adds per-architecture .apks release artifacts and changes what Obtainium offers by default, establishing a new installation/distribution workflow. This is not a user configuration option for the existing universal APK. The author says there was no prior discussion and the complete conversation contains no maintainer approval.

submission evidence: "No prior discussion. It only changes what the existing APK mirror uploads, and Play builds and signing are untouched."

Obtain maintainer approval of the split-APK release and installation workflow and link the approved scope.

thanks for trying to help improve t3 code. if you think this closure was a mistake, please open a fresh pr addressing the requirement above, and link back to this one.
