Integrating Interstitial Ads - Android

Interstitial Integration for Android Interstitial ads provide full-screen experiences, commonly incorporating rich media to offer a higher level of interactivity compared to banner ads. Interstitials are typically shown during natural transitions in your app, e.g. after completing a game level, or while waiting for a new view to load. You can use the `MoPubInterstitial` object and its associated listeners to fetch and display interstitial ads in your app.


Before integrating interstitial ads in your app, you’ll need to go through the steps in our Getting Started to create an account on MoPub and integrate the SDK into your project.

Sample code:

For a complete example of how to add interstitial ads into your app, check out the mopub-sample .

Load interstitial ads in your app:

1. Check your AndroidManifest.xml file Be sure you have the following permissions:

<uses-permission android:name="android.permission.INTERNET"></uses-permission>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"></uses-permission>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"></uses-permission>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>

`ACCESS_COARSE_LOCATION` or `ACCESS_FINE_LOCATION` are only needed if you want the device to automatically send the user’s location for targeting. `WRITE_EXTERNAL_STORAGE` is optional and only required for `MRAID 2.0` store picture ads. You’ll also need to include the following custom Activities (even though you won’t instantiate them directly):

<activity android:name="com.mopub.mobileads.MoPubActivity" android:configchanges="keyboardHidden|orientation"></activity>
<activity android:name="com.mopub.mobileads.MraidActivity" android:configchanges="keyboardHidden|orientation"></activity>
<activity android:name="com.mopub.common.MoPubBrowser" android:configchanges="keyboardHidden|orientation"></activity>
<activity android:name="com.mopub.mobileads.MraidVideoPlayerActivity" android:configchanges="keyboardHidden|orientation"></activity>

2. Create and display an interstitial ad

The MoPub SDK provides a custom class, `MoPubInterstitial`, that handles fetching and displaying fullscreen interstitial ads. To ensure a smooth experience, you should pre-fetch the content as soon as your `Activity` is created, then display it if the fetch was successful. In the `Activity` in which you want to show the interstitial ad, declare a `MoPubInterstitial` instance variable:

private MoPubInterstitial mInterstitial;

`MoPubInterstitial` provides a listener interface, `InterstitialAdListener`, which you’ll use to stay informed about ad lifecycle events. Make sure your `Activity` implements the `InterstitialAdListener` interface. In your `Activity`’s `onCreate()` method, instantiate the `MoPubInterstitial` using the context and the Ad Unit ID you created.

mInterstitial = new MoPubInterstitial(this, YOUR_INTERSTITIAL_AD_UNIT_ID_HERE);

Next, register your activity as the InterstitialAdListener:

// Remember that "this" refers to your current activity.

Now you’re ready to display an ad. Displaying the ad takes four steps:

1. In your `onCreate()` method, call `load()` to begin prefetching the ad. It’s important to fetch interstitial ad content well before you plan to show it, since it often incorporates rich media and may take some time to load. We suggest prefetching when your `Activity` is first created, but you may also choose to do it based on events in your app, like beginning a game level.

2. When you’re ready to display your ad, use `MoPubInterstitial.isReady()` to check whether the interstitial was successfully prefetched.

3. If `isReady()` returns true, display the interstitial by calling the `show()` method. You can add logic to the other interstitial lifecycle methods to handle what should happen when your user interacts with the ad– e.g. resuming your game `onInterstitialDismissed()`.

4. Lastly, remember to call `destroy()` on the interstitial in your `Activity`’s `onDestroy` method. Your completed `Activity` code should look something like this:

public class ExampleActivity extends Activity implements InterstitialAdListener {
    MoPubInterstitial mInterstitial;

    protected void onCreate(Bundle savedInstanceState) {
        mInterstitial = new MoPubInterstitial(this, YOUR_INTERSTITIAL_AD_UNIT_ID_HERE);

    protected void onDestroy() {

    // InterstitialAdListener methods
    public void onInterstitialLoaded(MoPubInterstitial interstitial) {
        if (interstitial.isReady()) {
        } else {
            // Other code

    public void onInterstitialFailed(MoPubInterstitial interstitial, MoPubErrorCode errorCode) {}

    public void onInterstitialShown(MoPubInterstitial interstitial) {}

    public void onInterstitialClicked(MoPubInterstitial interstitial) {}

    public void onInterstitialDismissed(MoPubInterstitial interstitial) {}
