All thanks to @CommonsWare for providing me with this wonderful solution I made this answer for others who have this type of problem. It is working now. This is exactly how i put it to work

    protected WebView webView;
    private static final String URL = "file:///android_asset/dancerkate.html";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        webView = (WebView)findViewById(R.id.local_tv01);
        webView.setWebViewClient(new WebViewClient());
        WebSettings webSettings = webView.getSettings();
        webSettings.setJavaScriptEnabled(true);
        webSettings.setJavaScriptCanOpenWindowsAutomatically(true);
        if(android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.JELLY_BEAN) {
            webSettings.setAllowFileAccessFromFileURLs(true);
            webSettings.setAllowUniversalAccessFromFileURLs(true);
        }



        refreshWebView(webView);

    }

    public void refreshWebView(View view) {
        webView.loadUrl(URL);
    }
