I managed to create an apk and tried to upload it to Google Play Console, but I got two errors. I am using Godot 3.0.6
This release is not compliant with the Google Play 64-bit requirement
The following APKs or App Bundles are available to 64-bit devices, but they only have 32-bit native code: 1.
From August 1, 2019 all releases must be compliant with the Google Play 64-bit requirement.
Include 64-bit and 32-bit native code in your app. Use the Android App Bundle publishing format to automatically ensure that each device architecture receives only the native code it needs. This avoids increasing the overall size of your app.
Target API level requirements from August 2019
Your app currently targets API level 27 and must target at least API level 28 to ensure it is built on the latest APIs optimized for security and performance.
From August 2019, new apps must target at least Android 9.0 (API level 28).
From November 2019, app updates must target Android 9.0 (API level 28).
