第一步，确保jdk,sdk,gradle版本一致

unity 3d的配置

idea配置

第二步，整个unity导出安卓项目到idea

idea配置项目（修改gradl配置）

gradle配置代码

distributionUrl=https\://services.gradle.org/distributions/gradle-8.7-bin.zip

插件代码：

plugins {
    // If you are changing the Android Gradle Plugin version, make sure it is compatible with the Gradle version preinstalled with Unity
    // See which Gradle version is preinstalled with Unity here https://docs.unity3d.com/Manual/android-gradle-overview.html
    // See official Gradle and Android Gradle Plugin compatibility table here https://developer.android.com/studio/releases/gradle-plugin#updating-gradle
    // To specify a custom Gradle version in Unity, go do "Preferences > External Tools", uncheck "Gradle Installed with Unity (recommended)" and specify a path to a custom Gradle version
    id 'com.android.application' version '8.6.0-alpha07' apply false
    id 'com.android.library' version '8.6.0-alpha07' apply false
}

第三步，unityLibrary导入到已有安卓项目

报错：

Caused by: org.gradle.api.resources.MissingResourceException: Could not read script 'D:\IDEA-items\quanji_xitong\shared\keepUnitySymbols.gradle' as it does not exist.

解决方法：

路径代码(需要变为自己的路径)：

apply from: 'D:/Unity_3D/Quanji_export-test/shared/keepUnitySymbols.gradle'

导入依赖包：

选择unityLibrary模块：

添加依赖：

  implementation(project(":unityLibrary"))

删除Gradle Projects方法

添加进程：

android:process=":UnityPlayerActivityProcess"
