Android Question Crashlytics - Failed to load WebView provider: No WebView installed

[Jerryk]

I have an application help written in html.

Private Sub B4XPage_Created (Root1 As B4XView)
    Root = Root1
    WebView1.Initialize("wv")
    Root.AddView(WebView1,0%x,0%y,100%x,100%y)
    WebView1.loadhtml(File.ReadString(File.DirAssets,"index.html"))
End Sub

On my, wife's smartphone, tablet it displays fine. Also in the Nox emulator.
But in the BlueStack emulator it crashes, Crashlytics shows the same error:

Any suggestions on how to solve this?

WebView is installed as a separate app in recent versions of Android. This error means that WebView is missing on these devices.

I guess that this is a rare crash. You can catch this error and show a message to the user.
