Google Play Developer Console shows app as unsigned

Question

I got the error: JAR_SIG_NO_SIGNATURES , when I try to publish my brand new app on the Play Store. I have tried checking the V1, V2, and both boxes together, none of them solved the issue. That seems to be the only solution I can find.

I am using app-release.apk and there are no errors upon the signed APK being built.

Answer 1

Just because you generate release type of your .APK doesn't mean it's being automatically signed. You need to get familiar with this steps to sign your app.

Bottom line, you need to generate a release key that will be used to sign your builds. This can be done various ways, the easiest one being following Android Studio IDE steps in

Build -> Generate Signed Bundle / APK

Answer 2

I realised as I took the screenshots that I wasn't logged into the owner account and hadn't yet accepted the terms of service to allow Google to manage app signing.

I contacted Google and asked for the owner email, which happened to be one I made years ago, then was allowed to accept and upload my app. Thanks all.

This is now resolved.
