Basic internal links don't work in honeycomb app?

Question

Internal links do not seem to be working in Android version 3 in my published app. My app targets Froyo at this point.

The app works fine on tons of phones, but my

Here is the solution I use. Works the same on all Android platform (tested on all 1.6 to 4.0.1)

Load the file as you would normally, without the anchor point. E.g.:

webview.loadUrl("file:///android_asset/file.html");

Load the URL without the anchor point (e.g. file:///android_asset/file.html), and add:

webview.setWebViewClient(new WebViewClient()
{
    public void onPageFinished(WebView view, String url)
    {
        if (this.anchor != null)
        {
            view.loadUrl("javascript:window.location.hash='" + this.anchor + "'");
            this.anchor = null;
        }
    }
});

where anchor is the anchor point you want to jump to.

you have to make sure javascript is enabled:

WebSettings webSettings = webview.getSettings();
webSettings.setJavaScriptEnabled(true);

This is for loading the file into the webview. Now if you want to catch internal links that are now broken, as suggested in the other answer, override the onReceivedError method and insert do something like:

    public void onReceivedError(WebView view, int errorCode, String description, String failingUrl)
    {
        int found = failingUrl.indexOf('#');

        if (found > 0)
        {
            anchor = failingUrl.substring(found + 1, failingUrl.length());
            view.loadUrl(failingUrl.substring(0, found));
        }
    }

Here is my workaround code so the bug is transparent to the user.
Define the WebViewClient for the browser, and include something like the following for onReceivedError:

        @Override
    public void onReceivedError(WebView view, int errorCode, String description, String failingUrl)
    {
        if (failingUrl.contains("#")) {
            Log.v("LOG", "failing url:"+ failingUrl);
            final int sdkVersion = Integer.parseInt(Build.VERSION.SDK);
            if (sdkVersion > Build.VERSION_CODES.GINGERBREAD) {
                String[] temp;
                temp = failingUrl.split("#");
                view.loadUrl(temp[0]); // load page without internal link

                try {
                    Thread.sleep(400);
                } catch (InterruptedException e) {

                    e.printStackTrace();
                }
            }

            view.loadUrl(failingUrl);  // try again
        } else {
             view.loadUrl("file:///android_asset/tableofcontents.html");
        }
    }
    });

This tricks the webview to first load the page without the #link, then sleep for .4 of a second, and then load the full URL again. I have chosen to do this trick for tablets only by sdkVersion. If there is any other error I load another page, the tableofcontents.html. This works to fix the problem on my Galaxy Tab.
