Unity3D:问题(成功):如何:Unity2020.3.17f1c1打包APK_a problem occurred configuring project ':launcher'

目录

一.目的

1.想知道:如何:Unity2020.3.17f1c1打包APK

二.参考

三.注意

1.设置一下JDK、SDK，不要使用UnityHUB下载的Android模块

1.操作:2:发现不需要设置密钥的

四.操作:1:成功:能够新建工程然后打包APK 

1.版本

1.过程

1.解决问题:失败:新建密钥+在OtherSettings中配置好PackageName、Minimun API Level、Target API Level等参数

1.解决报错:失败:修改API等级

1.解决报错:成功:不使用UnityHUB下载自带的Android模块

1.打包成功 

四.操作:2:成功:能够正常打包APK(因为写博客时候崩溃了,导致没有了,所以重新写一下内容)

1.版本:和操作:1:一致

1.主要的步骤

1.运行结果:成功:能够打包APK
