Android WebView "No 'Access-Control-Allow-Origin' header is present on the requested resource"

This is happening on the Javascript layer.
You can read up about it here : CORS

Are you sure you are not pausing timers in somewhere? Because this happens when you call mWebView.pauseTimers() when page loading.
