cocos creator3.x项目打包成aar 加入到已有的Android工程

Cocos crearor版本：  3.4.2

Android Studio Flamingo | 2022.2.1 Patch 2

1、配置构建安卓项目

2、 运行编译无报错

出现问题可尝试修改Gradle版本

 修改jdk版本

3、对libservice打包成aar

打包完后 再build/outputs找到aar

如果看不到Tasks模块，在File -> Settings -> Experimental 选项，取消勾选 Do not build Gradle task list during Gradle sync 选项

Android Studio 右侧 Gradle 不显示 tasks 模块_右侧gradle更新完成后才会出现模块吗-CSDN博客

4、对libcocos2dx打包成aar

5、对app游戏内容打包成aar

修改游戏项的build.gradle，本身导出安卓项是打包apk的，所以需要gradle，将内容改成library，并去掉无用项，

修改后

import org.apache.tools.ant.taskdefs.condition.Os

//将game工程作为library
apply plugin: 'com.android.library'

RES_PATH = RES_PATH.replace("\\", "/")
COCOS_ENGINE_PATH = COCOS_ENGINE_PATH.replace("\\", "/")

        }
    }
}

dependencies {
    //去掉其他aar的添加

}

修改AndroidManifest，去掉启动 

编译出aar 

6：其他项目组安卓工程，导入游戏aar资源，并加载呈现游戏

 在lib中加入导出的aar包

 在build.gradle中引入，game-release.aar不知道为啥引入失败，所以单独添加了

 MainActivity继承AppActivity就能使用了，如果本身游戏有其他安卓项需求，也可在AppActivity中实现再打包到aar中
