android - WebView problems in Kitkat device -

i'm trying create webview app, i'm testing in api 19 kitkat 4.4. when run code, i'm getting message not allowed load local resource: file:///android_asset/webkit/android-weberror.png. before i'm using kitkat device, it's worked on 4.3 device.

webview = (webview) getview().findviewbyid(r.id.webview);         webview.setwebviewclient(new mybrowser());         webview.getsettings().setloadsimagesautomatically(true);         webview.getsettings().setjavascriptenabled(true);         webview.setscrollbarstyle(view.scrollbars_inside_overlay);         webview.loadurl("http://www.google.com");`  `private class mybrowser extends webviewclient {         @override         public boolean shouldoverrideurlloading(webview view, string url) {             view.loadurl(url);             return true;
