Just wondering if anyone else is seeing this behaviour in a single Android 14
checkout location (android-platform-14.0.0_r4 in ~/firmware/aosp-14/ in my
case) when switching between ABIs for a target. * Build 1; x86_64 emulator
which does a full build as expected * Build 2; arm64-v8a emulator which does
pretty much a full build * Build 3; x86_64 emulator triggers lots of rebuilding
(seems to be mostly the final steps of apk creation and repackaging of image
files) * Build 4; arm64-v8a emulator again triggers lots of rebuilding (seems
to be mostly the final steps of apk creation and repackaging of image files)
(Each build consists of a new shell, then running envsetup.sh, lunch, and
finally m. out/ isn't cleared between builds) My expectation would be that
there'd be enough information in out/ for build 3 and build 4 to be close to a
no-op, but, instead, they're lengthy builds because most apps go through the
expensive APK assembly steps again; e.g. SettingsProvider

d8 Anyone else seeing this and have any thoughts on ways to speed up builds by
improving the cache hit rate?
