My tablet Android version is 7.0 and Chrome version 62.0.3202.84.
When first run my webview app, debug window show
Didn\'t find class \"andro
It appears to be a bug, more details here: https://groups.google.com/a/chromium.org/forum/#!topic/android-webview-dev/m0EtO3IXNn0
On N+ new ART logging appears to have been introduced letting app developers know about certain binary compatibility problems in their code. Unfortunately, this is triggering for some of the API-level guarded code in WebView.
One example is "Failed resolution of: Landroid/webkit/RenderProcessGoneDetail;", which is triggered whenever a recent version of WebView with O features is used on an N device. This is harmless, but confusing and spammy to developers looking at logcat.
