Unity mobile game doesn't link to androidX library, can't build

Unity Engine

Hi,

After enabling the androidX library by setting it to true in the gradle.Template properties file I’m still getting the same error and failed build stating I AndroidX is not enabled, please enable it and try again.

So I tried to put this script, which should ensure androidX is enabled when you try to make a build, into the Editor folder but the same error still occurs:

using System.IO;
using UnityEditor.Android;
using UnityEngine;
public class AndroidPostBuildProcessor : IPostGenerateGradleAndroidProject {
    public int callbackOrder {
        get {
            return 999;
        }
    }
    void IPostGenerateGradleAndroidProject.OnPostGenerateGradleAndroidProject(string path) {
        Debug.Log("Bulid path : " + path);
        string gradlePropertiesFile = path + "/gradle.properties";
        if (File.Exists(gradlePropertiesFile)) {
            File.Delete(gradlePropertiesFile);
        }
        StreamWriter writer = File.CreateText(gradlePropertiesFile);
        writer.WriteLine("org.gradle.jvmargs=-Xmx4096M");
        writer.WriteLine("android.useAndroidX=true");
        writer.WriteLine("android.enableJetifier=true");
        writer.Flush();
        writer.Close();
    }
}is not enabled

Can anyone tell me how to get this to work? There’s not much online about what to do if :
android.useAndroidX=true
android.enableJetifier=true

in the gradle template file doesn’t work. Frustrating!

Have you tried opening the exported project in Android Studio and building there?
