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 Automatic data collection, and how to integrate the MoPub SDK and adapter into an Android app.

Supported ad formats and features

The Ad Manager mediation adapter for MoPub has the following capabilities:

Formats
Banner
Interstitial
Rewarded
Native
Features
Adaptive banner
Automatic data collection

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.

Note: To add an ad unit to an existing app, navigate to the Apps page in the MoPub UI and select the app for which you want to add the ad unit. On your app's details page, click the Add an Ad Unit button.

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

Banner

Choose Tablet as the Device type. Choose a banner format that matches the ad size you're requesting in your app. Enter a Name for your ad unit.

The refresh rate is handled by the Google Mobile Ads SDK according to your refresh rate setting in the Ad Manager UI. So, we recommend using a high value for the Refresh Interval here (e.g. 1000 seconds).

Note: The Banner size chosen here should match the request size in your app. The adapter ignores the size passed during the banner ad request.

Interstitial

Choose Tablet as the Device type. Choose Tablet Full Screen as the Format. Enter a Name for your ad unit. Choose the type of Layout to present the ad in.

Native

Choose Tablet as the Device type. Choose Native (Custom layout) as the Format. Enter a Name for your ad unit.

Note: Your app is responsible for placing the ad when integrating native ads with the Google Mobile Ads SDK. The MoPub adapter is not responsible for ad positioning, only for passing back the native ad assets. It does not use the AdPlacer code. Therefore, the Ad positions setting is ignored.

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

Note: To find your Ad Unit ID for an already existing ad unit, navigate to the Apps page in the MoPub UI, select your ad unit under the Ad Units section and click the Code Integration button.

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 Ad Manager 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 Ad Manager ad unit

Sign in to your Ad Manager account. Navigate to Delivery > Yield groups and click the New yield group button.

Enter a unique Name for your yield group, set the Status to Active, select your Ad Format, and set the Inventory type to Mobile App. Under the Targeting > Inventory section, select the Ad Unit ID to which you want to add mediation.

Next, click the Add yield partner button.

If you already have a Yield partner for MoPub, you can simply select it. Otherwise, select Create a new yield partner.

Select MoPub as the Ad network and enter a unique Name. Enable Mediation and turn on Automatic data collection, and enter the API Key and Inventory Report ID obtained in the previous section. You don't need to enter a Username and Password. Click Save when finished.

Once the Yield partner is selected, choose Mobile SDK mediation as the Integration type, Android as the Platform, and Active as the Status. Enter the Ad Unit ID obtained in the previous section and a Default CPM value.

Click Save at the bottom of the page when done.

Note: Automatic data collection takes a few days to gather data before it can accurately calculate a Dynamic CPM value for a mediation network. Once the eCPM can be calculated, it will be automatically updated on your behalf.

Using rewarded ads

In the settings for your rewarded 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 Override reward settings from third-party ad networks when using mediation 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 {
    google()
    jcenter()
}

...
dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'androidx.appcompat:appcompat:1.0.2'
    implementation 'com.google.android.gms:play-services-ads:20.0.0'
    implementation 'com.google.ads.mediation:mopub:5.16.3.0'
}
...

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.

Navigate to the MoPub adapter artifacts on Google's Maven Repository. Select the latest version, download the MoPub adapter's .aar file, 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:

JAVA

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

KOTLIN

val bundle = MoPubAdapter.BundleBuilder()
   .setPrivacyIconSizeDp(15)
   .build()
val adRequest = PublisherAdRequest.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.

Field	Populated by MoPub adapter
Headline
Image
Body
App icon
Call to action
Star rating
Store
Price

Impression and Click Tracking

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

Error codes

If the adapter fails to receive an ad from MoPub, publishers can check the underlying error from the ad response using ResponseInfo.getAdapterResponse() under the following classes:

com.google.ads.mediation.mopub.MoPubAdapter
com.google.ads.mediation.mopub.MoPubMediationAdapter

Here are the codes and accompanying messages thrown by the MoPub adapter when an ad fails to load:

Error code	Reason
101	MoPub server parameters configured in the Ad Manager UI are missing/invalid.
102	The requested banner size does not map to a valid MoPub ad size.
103	Activity context is null.
104	Mopub SDK not initialized.
105	Wrong native ad type.
107	An ad is already loaded for this network configuration.
108	Ad expired.
110	Requires native ads.
111	Native ad is missing required assets.
112	Ad is not ready.
0-99	MoPub SDK error. See code for more details.
