Admob interstitial ad won't display

I used to display AdMob banner on my future apps, and I'd like to give a try to the interstitial ads.

I checked the AdMob SDK for implementation, and I copied their example source because it was exactly what I want (i.e. the interstitial shown when the activity launch).

I tried it on emulator and on my Galaxy, no ad has been displayed.

Here is the source code:

public class Asscreed extends Activity {
    private InterstitialAd interstitial;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_asscreed);

        // Create the interstitial.
        interstitial = new InterstitialAd(this);
        interstitial.setAdUnitId("ca-app-pub-6046034785851961/xxxxxx");

        // Create ad request.
        AdRequest adRequest = new AdRequest.Builder().build();

        // Begin loading your interstitial.
        interstitial.loadAd(adRequest);
    }

    // Invoke displayInterstitial() when you are ready to display an interstitial.
    public void displayInterstitial() {
        if (interstitial.isLoaded()) {
            interstitial.show();
        }
    }
}

The imports are OK and the Google Play Services library is of course imported.

I use this example: AdMob Android Guides - Interstitial Ad.

Could someone tell me what's wrong in my code?

Try initializing it in onCreate, but only call the show() method from an event, such as a button click.

You can use this code, the test ids work:

    @Override
    protected void onCreate(Bundle savedInstanceState) {
    ...

        MobileAds.initialize(this, "ca-app-pub-3940256099942544~3347511713"); //test id

        mInterstitialAd = new InterstitialAd(this);
        mInterstitialAd.setAdUnitId("ca-app-pub-3940256099942544/1033173712"); //test ad

        mInterstitialAd.loadAd(new AdRequest.Builder().build());


        btn_test.setOnClickListener(view -> {
            showInterstitial();
        });
...
    }    
    private void showInterstitial()
    {
        if (mInterstitialAd.isLoaded()) {
            mInterstitialAd.show();
        } else {
            Log.d("TAG", "The interstitial wasn't loaded yet.");
        }
    }

in your AndroidManifest you must put the tags

    <activity
        android:name="com.google.android.gms.ads.AdActivity"
        android:theme="@android:style/Theme.Translucent"
        tools:replace="android:theme" />
    <meta-data
        android:name="com.google.android.gms.ads.APPLICATION_ID"
        android:value="APP_ID" />
    <meta-data
        android:name="com.google.android.gms.ads.AD_MANAGER_APP"
        android:value="true" />
    <meta-data
        android:name="com.google.android.gms.version"
        android:value="@integer/google_play_services_version" />
