build-android-helper.sh compiled with whichever build-tools directory was newest on the
image while every lane that builds a helper installs exactly build-tools;36.0.0. That
selection feeds d8 and aapt2, so a newer package on the runner changed the helper's
bytecode and resources rather than just its packaging, and nothing said so.
The script now takes the version as an input, its last positional or
AGENT_DEVICE_ANDROID_BUILD_TOOLS, resolves it under $SDK_ROOT/build-tools, and checks the
four tools the build actually runs instead of aapt2 alone. An unpinned build is a hard
failure on CI; locally the newest-installed fallback stays and is announced on stderr.
Each lane that builds a helper declares the version it installs and interpolates that same
value into its sdkmanager line and the build environment, so an install and a build inside
one lane cannot drift. setup-android-replay-host exports it to the packaging gate and names
it in both helper cache keys, which are keyed on APK bytes; size.yml and
release-android-snapshot-helper.yml declare it at job level. The fixture-repack cluster
keeps its own pin: a different command family that ships no helper APK.
Closes#2527
* build(android): unify snapshot/ime helper build+package scripts
Replace the four ~75%-duplicated shell scripts with one parameterized
build script and one parameterized package script, mirroring
scripts/build-xcuitest-apple.sh's env-var-driven pattern. The helper
is selected via AGENT_DEVICE_ANDROID_HELPER or a first positional arg;
per-helper differences (HELPER_DIR/PACKAGE_NAME, snapshot's
test-compile+run step, ime's aapt2 resource-compile step, and the
manifest JSON fields) live in small case blocks.
All package.json entry points keep their names and output paths.
Verified byte-level equivalence between main and this branch: identical
unzip -l listings, identical classes.dex SHA-256 for both helpers, and
identical manifest fields (only the per-signing-run sha256 differs).
Fixes#1461
* chore: drop stale android/multitouch-helper .gitignore entries
The multitouch helper was consolidated away in #1281; these two lines
were never cleaned up.
