EDIT : SOLVED, SEE COMMENT
I'm getting this error while trying to upload my signed release APK to Google Play:
You uploaded an APK with an invalid signature (learn more about signing). Error from apksigner: ERROR: JARSIGNO_MANIFEST: Missing META-INF/MANIFEST.MF
Google isn't being very helpful so I'm turning to you. I'm using Godot 2.1.4 compiled from windows for windows because of a custom module I'm using, so I compile my own release export template for android using JDK 8, NDK 13b, and I've tried switching through many different versions of the SDK though for some reason when I run 'gradlew build' it always tries to revert to build-tools 26 even if I have other versions installed.
Really not sure where to even begin with this, any help is appreciated.
