# Checks that every ABI split of a flavor ships the same set of native libraries.
|
|
# Sourced by verify-abi-parity.sh; exercised directly by verify-abi-parity-selftest.sh.
|
|
#
|
|
# A dependency published for only some of our ABIs installs cleanly on the others and dies
|
|
# with UnsatisfiedLinkError the first time it is touched — nothing at build time says a word.
|
|
# That is #7001: maplibre-native-ffi 0.202608.3 ships arm64-v8a and x86_64 only, so the
|
|
# F-Droid armeabi-v7a split had no map engine and the map tab crashed the app.
|
|
|
|
# Gaps we know about and have decided to ship. One per line: <flavor> <abi> <lib>.
|
|
# An entry is checked both ways — the lib must be absent from that split, and the check
|
|
# fails once it turns up, so an entry cannot outlive its reason: the dependency bump that
|
|
# closes the gap goes red until the line is deleted with it.

# fdroid armeabi-v7a: no 32-bit ARM build of MapLibre exists yet. Upstream merged it on
|
|
# 2026-08-24 (maplibre-native-ffi #658/#659/#660); the release carrying it, and the
|
|
# maplibre-compose bump onto it, are what remove these two lines. Until then the app shows
|
|
# a message instead of a map on those devices (#7005).
