Proguard

Resolve SDK initialization failure when using Proguard​

When using Proguard provided by Unity, SDK initialization may fail with an exception message of Exception: Fail To Check OS Setting.

When using Proguard, you must register the package name of the BACKND SDK in Proguard's exception list. 

-keep class io.thebackend.unity.** {
    *;
}

If you are using BACKND's 1:1 inquiry plugin, you must create an additional exception list for the plugin. 

-keep class io.thebackend.unity.** {
    *;
}
-keep class io.thebackend.webview.** {
    *;
}
