I have javascript in a webview that only loads sometimes. Other times it doesn’t, this effects my page layout and functionality.

the obvious answer myWebView.getSettings().setJavaScriptEnabled(true); is already being used before my loadurl function

right now, both the html file and the jquery library file are being loaded from the assets folder. In the HTML code I am using <script type="text/javascript" src="jquery.min.js"></script> to load the jquery file locally

On the Java side within my onCreate() method:

 myWebView.getSettings().setJavaScriptEnabled(true);
 myWebView.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);
 myWebView.loadUrl("file:///android_asset/newtry.html");

The HTML file
<html>
<head>
<script type="text/javascript" src="jquery.min.js"></script>
<script> //the custom jquery functions, no more includes </script>
<style type="text/css">
//the css
</style>
</head>
<body>

these files – the HTML and the jquery.min.js are in the same folder assets

what else can I do?

    The answer is that you have to force the app to wait (try it, place a breakpoint at your webview, and then let it continue, you’ll see the webview will load with javascript this time, reliably. Whereas if you just let the app load without the breakpoint, it frequently “skips” the javascript). Some sort of forced threaded wait method is needed.

    A second method is to force the javascript to load after the page is loaded, as shown by the author’s answer here android: webview not loading javascript with custom WebViewClient
