Automatic build of Hikari from the latest main — the app as it is right now,
not a versioned release.
Install hikari-signed.apk (the universal build: works on every phone; allow
unknown sources). The two smaller ones are for one processor type each —
hikari-arm64-v8a.apk for almost every phone made since ~2016, and
hikari-armeabi-v7a.apk for older 32-bit devices.
Android may warn about an unknown developer; that is expected for a direct APK.
The versioned releases above are the ones to use if you want a tested build.
