As of Android KitKat, the WebView component has been migrated into a variant of Chromium. This may cause existing content to fail to load, or cause other undesirable results when attempting to run WebView API calls on the UI thread.
Use the [code]runOnUiThread[/code] method when performing any calls involving the WebView to resolve this issue.
For additional information, please reference the core documentation outlined below: https://developer.android.com/guide/webapps/migrating.html#Threads
