Loading a Maps API site in a Native Android Application-Collection of common programming errors

Filtered it down to

private void setupWebView() {
        /*
            final String centerURL = "javascript:centerAt("
                    + mostRecentLocation.getLatitude() + ","
                    + mostRecentLocation.getLongitude() + ")";
            webView = (WebView) findViewById(R.id.webview);
            webView.getSettings().setJavaScriptEnabled(true);
            // Wait for the page to load then send the location information
            webView.setWebViewClient(new WebViewClient() {
                @Override
                public void onPageFinished(WebView view, String url) {
                    webView.loadUrl(centerURL);
                }

            });*/
            webView = (WebView) findViewById(R.id.webview);
            webView.loadUrl(MAP_URL);
    }

Bit easier to filter out the actual issue when you know which bit doesnt work thanks to CommonsWare for the great book, poking through that and test-code that ACTUALLY WORKS made it a bit easier to work out what was going on. And thanks for the debug info :o)
