Does any one have ideas on why gradle could produce an unsigned apk? I do properly setup signing configs, I checked and rechecked. I even diffed my

build.gradle

with another project which has exaclty same signing configs and produces a signed apk, but this one isn't.

$ jarsigner -verify /path/to/apk

jar is unsigned

this is not related to Kotlin so you should ask on StackOverflow

OK, sorry.

you should reach out to their support and tell them that they're doing it wrong

This is the plan, now that I just found out what causes this 🙂

There's more details at https://source.android.com/security/apksigning. v1 is only needed for old API levels and is not done by default for higher ones

I tried to enable it explicitly, but it still failed to upload for some reason, maybe I've messed up something
