Unauthorized modifications to this JAR entry will not be detected

Building android app for production.
Kind of an extra step I run apksigner verify -v filename
To to verify the Jar is signed.

Recently I have been getting warning.
WARNING: META-INF/android.arch.core_runtime.version not protected by signature. Unauthorized modifications to this JAR entry will not be detected. Delete or move the entry outside of META-INF/.

I get about 20 of this warnings.

Not sure how I would even fix that with Ionic?

hi @helpmelearn did you find solutions to your issue ?

No, this still happens. I assume they want us to use a newer build method.

Hi, i’m facing the same issue. this is my first time doing production.
Should i just ignore these warnings? or is there a workaround?

Advice is needed. Thanks.

As far as I can tell there is only one way to build ionic apps. So because of this they don’t use the newer android way. I guess it could be related to my cordova version and or my cordova-android version (6.3) that is just how it builds. Not sure which version of either of these you are guys are using.
