Can not acess url from Webview in Android
===

I am trying to access the url using the shouldOverrideUrlLoading method. I have stored my html files in the assets folder but for some reason when I try to access the url I get Web page not available error.Previously I could access the url because I stored my html file in the raw folder but I needed to move it to assets folder as the code looks cleaner this way. This is my code, could anyone please let me know how I can resolve this.

    webview.setWebChromeClient(new WebChromeClient());
    webview.setWebViewClient(new WebViewClient());
    webview.loadUrl("file:///android_asset/myfile/file.html");
    webview.setVerticalScrollBarEnabled(false);
    webview.setWebViewClient(new WebViewClient()
    {
        public boolean shouldOverrideUrlLoading(WebView view, String url) {

        	if (url.equalsIgnoreCase("some text")){
        		setDialog("some fancy text");
        	}
