You need to set WebChromeClient(This handles JavaScript dialogs, favicons, titles, and the progress) for your WebView .

WebView wView = new WebView(this){
            @Override
            public boolean onJsAlert(WebView view, String url, String message,
                    JsResult result) {
                // TODO Auto-generated method stub
                Log.i("my log","Alert box popped");
                return super.onJsAlert(view, url, message, result);
            }
};
setContentView(wView);

wView.getSettings().setJavaScriptEnabled(true);

WebChromeClient cClient = new WebChromeClient();
wView.setWebChromeClient(cClient);

wView.loadUrl("file:///android_asset/" + yourHtmlFile);

Hope it helps :)
