exporting unity game as android APK issue

Question

I am currently exporting my game as APK however I am coming across a lot of errors that seem a bit vague for me.

I am using the highest setting for the API and I am also making sure to enter the keystore password.

I am getting 3 errors which I will list below in the code blocks.

Can somebody help with that?

Answer 1

This is because of 'android.enableR8' is deprecated. To remove it from gradle.properties file you have to go to Project Settings > Player > (Android Tab) > Other Settings > and marking "Custom Gradle Properties Template".

After that a gradleTemplate.properties file is generated at "Assets/Plugins/Android/gradleTemplate.properties".

In this file remove line 'android.enableR8' or comment it out and now make new fresh build.

This trick should work.
