    First of all, the browser you mentioned is a browser on your device or is it a browser in a computer?

    Now, if it worked in the android browser (or a browser in your device), then the problem is because the javascript files are on your assets folder. When you indicate a resource through relative path (the way you are using), the webview searchs it relative to the same folder as your html file is. Since you are using a String as your “html file”, I would recommend using the loadDataWithBaseURL(). I made an usage example below using the assets folder as the base URL, try it.

    web_view.loadDataWithBaseURL("file:///android_asset/", data, "text/html", "UTF-8",null);

    public void loadDataWithBaseURL (String baseUrl, String data, String mimeType, String encoding, String historyUrl)

    Added in API level 1
    Loads the given data into this WebView, using baseUrl as the base URL for the content. The base URL is used both to resolve relative URLs and when applying JavaScript’s same origin policy. The historyUrl is used for the history entry.

    Note that content specified in this way can access local device files (via ‘file’ scheme URLs) only if baseUrl specifies a scheme other than ‘http’, ‘https’, ‘ftp’, ‘ftps’, ‘about’ or ‘javascript’.

    If the base URL uses the data scheme, this method is equivalent to calling loadData() and the historyUrl is ignored.

    Parameters
    baseUrl the URL to use as the page’s base URL. If null defaults to ‘about:blank’.
    data a String of data in the given encoding
    mimeType the MIMEType of the data, e.g. ‘text/html’. If null, defaults to ‘text/html’.
    encoding the encoding of the data
    historyUrl the URL to use as the history entry. If null defaults to ‘about:blank’.

    You can try passing the assets folder as the baseUrl, so my guess would be that your code would be like this

    Hope this helps!
