支持 Android 和 IOS 录屏，并保存到相册中。

官方示例场景：Plugins/VoxelBusters/ReplayKit/Examples/Scenes/ReplayKitDemo.unity

亲测成功!
Redmi Note 11T Pro

导入SDK，打包报错 Failed to update Android SDK package list. See the Console for details.
解决方法：
1、【Windows】-> Preferences -> External Tools -> 取消所有 xxxxx packages 的勾选
2、重启 Unity
3、将刚才取消的勾选重新勾上
4、点击 Play，强制刷新
5、重新打包

打包报错 This project uses AndroidX dependencies, but the 'android.useAndroidX' property is not enabled. Set this property to true in the gradle.properties file and retry.
解决方法：在gradleTemplate.properties文件中增加以下两句
android.useAndroidX=true
android.enableJetifier=true
