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("\\", "/")
