- In Project Settings - Android select store version:. [your version number] - e.g. ‘13’
- Tick the Support armv7 [aka armeabi-v7a] and make sure arm64 is NOT ticked.
- Build for Android - That’s the 32bit APK
- Project Settings - Android select store version:. [your version number] - e.g. ‘14’ (one increment higher)
- Tick the Support arm64 [aka arm64-v8a] and make sure armv7 is NOT ticked.
- Build for Android - That’s the 64bit APK
In Google playstore under ‘Release Management’ / App releases - select a track - create release - ‘Android App Bundles and APKs to add’ - and upload the 32 bit APK first. Then in the same ‘Android App Bundles and APKs to add’ upload the 64bit APK.
I think I got the error above, because I uploaded it in the wrong order(like having the 64bit version with a lower version number and uploading it first).
