三、解决方案

1. 原因：

Unity 2021 不再支持直接在Assets/Plugins/Android/res目录下放置Android资源

2. 解决方法
   （1）Assets/Plugin/Android文件夹下，创建res.androidlib文件夹，并把res文件夹移入res.androidlib下
   （2）创建AndroidManifest.xml文件，添加以下内容，并文件移入res.androidlib文件夹下

<?xml version = "1.0" encoding = "utf-8" ?>
<manifest xmlns:android = "http://schemas.android.com/apk/res/android" package = "custom.android.res" android:versionCode = "1" android:versionName = "1.0" >
</manifest >
