onPageFinished doesn´t work with ads - webview

Question

I'm trying to show interstitial ads in some urls of my webview app, including onPagefinished and url.contains, but it doesn´t work. Here's my code:
#SuppressLint("SetJavaScriptEnabled") public class Juego extends ActionBarActivity {
/** ID intersticial */
private InterstitialAd interstitialAd;
private static final String AD_UNIT_ID = "ca-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_juego);
//Página web enlazada:
WebView myWebView = (WebView) findViewById(R.id.webview);
myWebView.loadUrl("http://xxxxxxxxxxxxxxxxx.php");
WebSettings webSettings = myWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
myWebView.setWebViewClient(new WebViewClient());
myWebView.setVerticalScrollBarEnabled(false);
myWebView.setHorizontalScrollBarEnabled(false);
//Barra de progreso
final Activity activity = this;
final ProgressDialog progressDialog = new ProgressDialog(activity);
progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
progressDialog.setCancelable(false);
myWebView.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress) {
progressDialog.setTitle("Cargando");
progressDialog.setMessage("Por favor espera");
progressDialog.show();
progressDialog.setProgress(0);
activity.setProgress(progress * 1);
progressDialog.incrementProgressBy(progress);
if(progress == 100 && progressDialog.isShowing())
progressDialog.dismiss();
}
});
}
public void onPageFinished (WebView view, String url) {
// Anuncios intersticiales: Create the interstitial.
interstitialAd = new InterstitialAd(this);
interstitialAd.setAdUnitId(AD_UNIT_ID);
// Create ad request.
AdRequest adRequest = new AdRequest.Builder().build();
// Begin loading your interstitial.
interstitialAd.loadAd(adRequest);
if (url.contains("game")) {
interstitialAd.show();
}
}
}
Any help?

use this
public void onPageFinished (WebView view, String url) {
interstitial = new InterstitialAd(this);
interstitial.setAdUnitId("ca-app-pub-5236990339136194/xxxxxxxxxx");
// Begin loading your interstitial.
interstitial.loadAd(adRequest);
interstitial.setAdListener(new AdListener(){
public void onAdLoaded(){
displayInterstitial();
}
// Invoke displayInterstitial() when you are ready to display an interstitial.
public void displayInterstitial() {
if (interstitial.isLoaded()) {
interstitial.show();
}
}
} );
}
and don't forget add this on your onCreate blog
AdView adView = (AdView) this.findViewById(R.id.adView);
AdRequest adRequest = new AdRequest.Builder().build();
adView.loadAd(adRequest);
