AndroidJavaException NoSuchFieldError "forceBringToFront"

[Enormus]

Hello @KojiNakamaru,

First, thank you for your excellent plugin! We've been using it successfully for two years now in our app:

XRAI Glass

which has helped thousands all around the world!

Today we upgraded to the latest unitypackage and we are currently building with Unity 2022.3.50f1. After the upgraded we received the following exception immediately upon start:

Commenting out this single line in WebViewObject.cs resolves the issue and the app seems to function as expected. (I have not tested extensively yet so I don't know if commenting this out has broken anything else.)

#if UNITY_2021_1_OR_NEWER
    //  webView.SetStatic<bool>("forceBringToFront", true); // commenting this out no longer throws
#endif

Thank you so much!

I pushed two branches where one utilizes Packages/manifest.json to import the plugin and another directly imports the plugin by unity-webview.unitypackage. Both work without any issue.

You might incompletely import files and still have old *.aar.tmpl. Please remove all files previously imported. Utilizing manifest.json is recommended as Package Manager treats any update correctly.
