Integrating MoPub with Mediation

This guide is for publishers who want to use the Google Mobile Ads SDK to load and display ads from MoPub via mediation. It covers how to add MoPub to an ad unit's mediation configuration, how to set up Ad Network Optimization (ANO), and how to integrate the MoPub SDK and adapter into an Android app.

Supported ad formats and features

The AdMob mediation adapter for MoPub has the following capabilities:

Requirements

• Android SDK 4.4 (API level 19) or higher

• Latest Google Mobile Ads SDK

Step 1: Set up MoPub

First, sign up and log in to your MoPub UI. Navigate to the Apps page and click the Add a New App button.

Select Android as the Platform for your app, enter the App name and Package name of your app. Then select a primary and secondary category of your app from the provided list.

MoPub requires you to create your first ad unit before you can finish adding your app.

For additional instructions on creating an ad unit, select the tab corresponding to your preferred ad format.

Click Save and View Code Integration to get your Ad Unit ID.

In addition to the Ad Unit ID, you'll also need to obtain your MoPub API Key and Inventory Report ID to set up your AdMob ad unit ID. To find your API Key and Inventory Report ID, navigate to the Reports page and click View API Access Details.

MoPub Marketplace

To get ads from MoPub, your account must be approved for MoPub Marketplace. During your initial account setup, you will be prompted to go through the process for Marketplace approval. Part of this process includes entering your payment information.

See the Marketplace setup guide for more details.

Step 2: Configure mediation settings for your AdMob ad unit

You need to add MoPub to the mediation configuration for your ad unit. First sign into your AdMob account.

Next, navigate to the Mediation tab. If you have an existing mediation group you'd like to modify, click the name of that mediation group to edit it, and skip ahead to Add MoPub as an ad source.

To create a new mediation group, select Create Mediation Group.

Enter your ad format and platform, then click Continue.

Give your mediation group a name, and select locations to target. Next, set the mediation group status to Enabled. Then click Add Ad Units, which will open up the ad unit selection overlay.

Associate this mediation group with your existing AdMob ad unit. Then click Done.

You should now see the ad units card populated with the ad units you selected.

Add MoPub as an ad source

In the Ad Sources card, select Add Ad Network. Then select MoPub.

Enable the Optimize switch. Enter the API Key and Inventory Report ID obtained in the previous section to set up ANO for MoPub. Then enter an eCPM value for MoPub and click Continue.

Next, enter the Ad Unit ID obtained in the previous section. Then click Done.

Finally, click Save.

Using rewarded video ads

In the settings for your rewarded video ad unit, provide values for the reward amount and reward type. Then, to ensure you provide the same reward to the user no matter which ad network is served, check the Apply to all networks in Mediation groups box.

If you don't apply this setting, the MoPub adapter passes back the reward specified in the MoPub dashboard.

Step 3: Import the MoPub SDK and adapter

Android Studio integration (recommended)

Add the following Maven repository and the implementation dependencies with the latest versions of the MoPub SDK and adapter to your app-level build.gradle file:

repositories {
    jcenter()
}

...
dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'androidx.appcompat:appcompat:1.0.2'
    implementation 'com.google.android.gms:play-services-ads:19.5.0'
    implementation 'com.google.ads.mediation:mopub:5.14.0.0'
}
...

Migrate project to AndroidX

The MoPub SDK depends on Android support libraries but the latest Google Mobile Ads SDK uses Jetpack libraries.

To ensure the MoPub SDK and the Google Mobile Ads SDK are compatible, create a gradle.properties file in the top-level of your project, and add the following code:

android.useAndroidX=true
android.enableJetifier=true

This will rewrite the MoPub SDK binary to use use Jetpack libraries. See AndroidX migration guide for more information about these settings.

Manual integration

Download the latest version of the MoPub SDK's source from their GitHub repo and add it to your project.

Download the latest .aar file of the MoPub adapter from Bintray, located under the Files tab, and add it to your project.

Step 4: Additional code required

No Additional code required for MoPub integration.

Step 5: Test your implementation

To get test ads from MoPub, you need a guaranteed or backfill line item. MoPub recommends adding the Demo line item to your ad unit to get test ads. The Demo line item is added to your MoPub account by default.

The Demo Line Item contains test creatives for native and banner ad units by default, but does not have a test creative for interstitial ad units. To add your own test creative for interstitial ads, you need to upload a simple image to the MoPub UI by navigating to the Demo Line Item and clicking the Add a New Creative button. Choose Tablet Full Screen format. Fill the form with the necessary details and click Save to add your test creative to the Demo Line Item.

That's it! You now have a working mediation integration with MoPub.

Optional steps

EU Consent and GDPR

Under the Google EU User Consent Policy, you must ensure that certain disclosures are given to, and consents obtained from, users in the European Economic Area (EEA) regarding the use of device identifiers and personal data. This policy reflects the requirements of the EU ePrivacy Directive and the General Data Protection Regulation (GDPR). When seeking consent, you must identify each ad network in your mediation chain that may collect, receive, or use personal data and provide information about each network's use. Google currently is unable to pass the user's consent choice to such networks automatically.

To collect consent for MoPub, MoPub asks that you use its consent mechanism. See the MoPub GDPR Publisher Integration Guide for more information.

Permissions

If the user's location needs to be used for the targeting, MoPub recommends adding the following optional permission into your app's AndroidManifest.xml file:

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

MoPub recommends adding the following optional permission for MRAID 2.0:

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

Using native ads

Network-specific parameters

The MoPub adapter supports an additional request parameter which can be passed to the adapter using the MoPubAdapter.BundleBuilder class. This class includes the following method:

• setPrivacyIconSizeDp(int)
  • Sets the privacy icon size in dp. Values can range from 10 to 30 inclusive. The default size for the privacy icon is 20 x 20 dp.

Here's a code example of how to set this ad request parameter:

Bundle bundle = new MoPubAdapter.BundleBuilder()
   .setPrivacyIconSizeDp(15)
   .build();
AdRequest adRequest = new AdRequest.Builder()
   .addNetworkExtrasBundle(MoPubAdapter.class, bundle)
   .build();

val bundle = MoPubAdapter.BundleBuilder()
   .setPrivacyIconSizeDp(15)
   .build()
val adRequest = AdRequest.Builder()
   .addNetworkExtrasBundle(MoPubAdapter::class.java, bundle)
   .build()

Ad Rendering

The MoPub adapter returns its native ads as UnifiedNativeAd objects. It populates the following fields for a UnifiedNativeAd.

Impression and Click Tracking

MoPub and Google Mobile Ads SDKs track impressions and clicks in their own way, so there may be discrepancies.
