I am not saving anything in OnSavedInstanceState().

Answer 1

add

webView.getSettings().domStorageEnabled = true 

before load url and after load url add these two line it will works.

webView.webChromeClient = WebChromeClient()
webView.webViewClient = WebViewClient()

Answer 2

the WebView itself might be saving a large state which exceeds the Binder transaction buffer limit.

override fun onSaveInstanceState(outState: Bundle) {
    super.onSaveInstanceState(outState)
    outState.putParcelable("android:webViewState", null)
}

this replace the WebView state with a null value, ensuring that it doesn't get saved.
