Xamarin.forms: [Bug] String resource ID #0x2040003 on WebViewRenderer

[Skirtek]

Description

I have custom WebView renderer in my app which inherits from WebViewRenderer. When I'm trying to open this WebView in my app on Android 5.1 device it crashes in base.OnElementChanged(e) invoke with exception: NotFoundException: String resource ID #0x2040003
According to this https://stackoverflow.com/questions/41025200/android-view-inflateexception-error-inflating-class-android-webkit-webview it could be exception from Google native library - androidx.appcompat

Steps to Reproduce

1. Create WebView renderer and use it in app
2. I'm convinced that this step is not necessary but you can try. Override OnElementChanged and call base method.
3. Open WebView in app on Android 5.1 device
4. Crash occurs

Expected Behavior

App does not crash

Actual Behavior

Crash occurs every time when I try to open custom WebView

[monolara]

Hi, is there any fix on this or any workaround?

[Skirtek]

@monolara I think it get stucked in TO DO column :(

[maarkristof]

On the last preview release (Xamarin.Forms.4.7.0.848-pre3), it doesn't crash for me, but all I got is a white screen.

[maarkristof]

Finally works on the last pre4 release.

[Skirtek]

@maarkristof I can not agree. I tested application on pre3, pre4 and 4.7. It is not fixed yet. Any hopes to fix this soon?

[Skirtek]

@monolara Finally I found working solution! In MainActivity declare: ConfigurationChanges = ConfigChanges.UiMode and it works! Credits: https://stackoverflow.com/a/58684213/6457073
