Android WebView for Facebook Like Button

To get past the blank page you do this:

 webview.setWebViewClient(new LikeWebviewClient(this));

 private class LikeWebviewClient extends WebViewClient {        
    @Override
    public void onPageFinished(WebView view, String url) {
        Log.d(TAG, "onPageFinished url: " +url);
        // Facebook redirects to this url once a user has logged in, this is a blank page so we override this
        // http://www.facebook.com/connect/connect_to_external_page_widget_loggedin.php?............
        if(url.startsWith("http://www.facebook.com/connect/connect_to_external_page_widget_loggedin.php")){
            String redirectUrl = getFacebookLikeUrl();
            view.loadUrl(redirectUrl);
            return;
        }
        super.onPageFinished(view, url);
    }
}
