final WebView webView = (WebView) findViewById(R.id.webView);
webView.loadUrl("http://polamreddyn.blogspot.in/2013/01/android-text-links-using-linkify.html");

webView.setWebViewClient(new WebViewClient() {
@Override
public void onPageFinished(WebView view, String url) {
Log.i("", "" +url);

@SuppressWarnings("deprecation")
                              // here by default "of" selected
int i = webView.findAll("of"); // is not supposed to crash
Toast.makeText(getApplicationContext(), "Found " + i + " results !", Toast.LENGTH_SHORT).show();
try {
Method m = WebView.class.getMethod("setFindIsUp",Boolean.TYPE);
m.invoke(webView, true);
