How To preload AdMob interstitial ad and send to another android activity using intent

Question

I need some help regarding AdMob interstitial ad.

I want to preload the interstitial ad in one activity. this is straight forward.

// Create an ad.
        interstitialAd = new InterstitialAd(this);
        interstitialAd.setAdUnitId(AD_UNIT_ID);

        AdRequest adRequest = new AdRequest.Builder()
                .addTestDevice(AdRequest.DEVICE_ID_EMULATOR)
                .addTestDevice(TEST_DEVICE_ID).build();

        // Load the interstitial ad.
        interstitialAd.loadAd(adRequest);

Now I want to send the interstitial Ad to another activity using intent. I don't know how to send it using

intent.putExtra("myAd", interstitialAd);

Thanks in advance.

Interstitial ads are not meant or built to be passed around like that using intents' extras.

It's better to

• recreate & reload an ad in the next activity
• make an extra public class that holds the interstitial ad, put it there in activity A and retrieve it from there in activity B

Example for 2nd case (semi pseudo code):

public class AdManager {
    // Static fields are shared between all instances.
    static InterstitialAd ad;
    private Context ctx;

    public AdManager(Context ctx) {
        this.ctx = ctx;
        createAd();
    }

    public void createAd() {
        // Create an ad.
        ad = new InterstitialAd(ctx);
        ad.setAdUnitId(AD_UNIT_ID);

        final AdRequest adRequest = new AdRequest.Builder()
                .addTestDevice(AdRequest.DEVICE_ID_EMULATOR)
                .addTestDevice(TEST_DEVICE_ID).build();

        // Load the interstitial ad.
        ad.loadAd(adRequest);
    }

    public InterstitialAd getAd() {
        return ad;
    }
}

Using

Activity A

AdManager adManager = new AdManager();
adManager.createAd();

Activity B

AdManager adManager = new AdManager();
InterstitialAd ad = adManager.getAd();
if (ad.isLoaded()) {
    ad.show();
}
