How to show interstitial ad without using a button.

[Gecooo]

My main problem is, the game is written in javascript while the admob is based on C# so I'm having a hard time building the code.

I tried using the GoogleMobileAdsDemoScript by dragging it to my main menu's Main Camera.

This is the code i used:

void Start();

{

RequestInterstitial();

ShowInterstitial();

}

private void RequestInterstitial()
    {
        #if UNITY_EDITOR
            string adUnitId = "unused";
        #elif UNITY_ANDROID
            string adUnitId = "INSERT_ANDROID_INTERSTITIAL_AD_UNIT_ID_HERE";
        #elif UNITY_IPHONE
            string adUnitId = "INSERT_IOS_INTERSTITIAL_AD_UNIT_ID_HERE";
        #else
            string adUnitId = "unexpected_platform";
        #endif

        // Create an interstitial.
        interstitial = new InterstitialAd(adUnitId);
        // Register for ad events.
        interstitial.AdLoaded += HandleInterstitialLoaded;
        interstitial.AdFailedToLoad += HandleInterstitialFailedToLoad;
        interstitial.AdOpened += HandleInterstitialOpened;
        interstitial.AdClosing += HandleInterstitialClosing;
        interstitial.AdClosed += HandleInterstitialClosed;
        interstitial.AdLeftApplication += HandleInterstitialLeftApplication;
        // Load an interstitial ad.
        interstitial.LoadAd(createAdRequest());
    }

    // Returns an ad request with custom ad targeting.
    private AdRequest createAdRequest()
    {
        return new AdRequest.Builder()
                .AddTestDevice(AdRequest.TestDeviceSimulator)
                .AddTestDevice("0123456789ABCDEF0123456789ABCDEF")
                .AddKeyword("game")
                .SetGender(Gender.Male)
                .SetBirthday(new DateTime(1985, 1, 1))
                .TagForChildDirectedTreatment(false)
                .AddExtra("color_bg", "9B30FF")
                .Build();

    }

    private void ShowInterstitial()
    {
        if (interstitial.IsLoaded())
        {
            interstitial.Show();
        }
        else
        {
            print("Interstitial is not ready yet.");
        }
    }

#region Interstitial callback handlers

    public void HandleInterstitialLoaded(object sender, EventArgs args)
    {
        print("HandleInterstitialLoaded event received.");
    }

    public void HandleInterstitialFailedToLoad(object sender, AdFailedToLoadEventArgs args)
    {
        print("HandleInterstitialFailedToLoad event received with message: " + args.Message);
    }

    public void HandleInterstitialOpened(object sender, EventArgs args)
    {
        print("HandleInterstitialOpened event received");
    }

    void HandleInterstitialClosing(object sender, EventArgs args)
    {
        print("HandleInterstitialClosing event received");
    }

    public void HandleInterstitialClosed(object sender, EventArgs args)
    {
        print("HandleInterstitialClosed event received");
    }

    public void HandleInterstitialLeftApplication(object sender, EventArgs args)
    {
        print("HandleInterstitialLeftApplication event received");
    }

    #endregion

 
I want to call then show the interstitial ad automatically whenever it's ready. 


I also tried this:

using GoogleMobileAds.Api;
...
// Initialize an InterstitialAd.
InterstitialAd interstitial = new InterstitialAd("MY_AD_UNIT_ID");
// Create an empty ad request.
AdRequest request = new AdRequest.Builder().Build();
// Load the interstitial with the request.
interstitial.LoadAd(request);

if (interstitial.IsLoaded()) {
  interstitial.Show();
}       

nothing happened using both codes above.

An interstitial takes at least a few seconds to load, so you can't call those two snippets one after another. In practice, you want to preload the interstitial at an earlier point in time (say, the start of your game level), and then at a later point in time (say the user completes the level), show the interstitial if it's loaded.
