Integrate maio with Mediation

This guide shows you how to use the Google Mobile Ads SDK to load and display ads from maio using mediation, covering waterfall integrations. It covers how to add maio to an ad unit's mediation configuration, and how to integrate the maio SDK and adapter into an Android app.

The dashboard interface for maio uses Japanese text for its labels, buttons, and descriptions, and the screenshots in this guide have not been translated. In this guide's descriptions and instructions however, labels and buttons are referenced with their English language equivalents. "URL スキーム," for example, is "URL Scheme".

Supported integrations and ad formats

The mediation adapter for maio has the following capabilities:

Integration
Bidding
Waterfall
Formats
Banner
Interstitial
Rewarded
Native

Requirements

  • Android API level 21 or higher
  • maio SDK 1.0.7 or higher

Step 1: Set up configurations in maio UI

First, sign up or log in to your maio account. Click the Application management button on the left sidebar and click on New app.

Select the tab corresponding to your preferred Ad Type.

Interstitial

Enter the Name of your app, select the platform and provide your App URL. Select Video interstitial as the Ad Type, and then click Update.

Rewarded

Enter the Name of your app, select the platform and provide your App URL. Select Video Rewards as the Ad Type, and then click Update.

In the Application Management page, make a note of the Media ID. It's needed to set up your Ad Manager ad unit in the next section.

In the Zone Management page, make a note of the Zone ID. It will also be needed to set up your Ad Manager ad unit in the next section.

In addition to Media ID and Zone ID, you will need API ID and API KEY to set up your ad unit ID for mediation. In Reporting API page, make a note of API ID and API KEY.

Step 2: Set up maio demand in Ad Manager UI

Configure mediation settings for your 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 under Inventory and Mobile application to which you want to add mediation.

Next, click the Add yield partner button.

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

Select maio as the Ad network, enter a unique Name and enable Mediation.

Turn on Automatic data collection, and enter the API ID and API KEY obtained in the previous section.

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 Media ID and Zone ID obtained in the previous section. Then, enter a Default CPM value.

Click Save at the bottom of the page when done.

Step 3: Import the maio SDK and adapter

In your project-level settings.gradle.kts file, add the following repositories:

dependencyResolutionManagement {
  repositories {
    google()
    mavenCentral()
    maven {
      url = uri("https://imobile-maio.github.io/maven")
    }
  }
}

Then, in your app-level build.gradle.kts file, add the following implementation dependencies and configurations. Use the latest versions of the maio SDK and adapter:

dependencies {
    implementation("com.google.android.gms:play-services-ads:23.6.0")
    implementation("com.google.ads.mediation:maio:1.1.16.3")
}

Manual integration

  • Download the latest version of maio Android SDK and add it to your project.
  • Navigate to the maio adapter artifacts on Google's Maven Repository. Select the latest version, download the maio adapter's `.aar' file, and add it to your project.

Step 4: Add required code

No additional code is required for maio Android integration.

Step 5: Test your implementation

Enable test ads

Make sure you register your test device for Ad Manager.

Publishers using version 11.6.0 or higher of the Google Mobile Ads SDK will automatically receive test ads from maio on phones and tablets registered as test devices when making requests.

Verify test ads

To verify that you are receiving test ads from maio, enable single ad source testing in ad inspector using the maio (Waterfall) ad source(s).

Error codes

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

Format Class name
Interstitial jp.maio.sdk.android.mediation.admob.adapter.Interstitial
Rewarded jp.maio.sdk.android.mediation.admob.adapter.Rewarded

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

Error code Reason
0-10 maio returned an SDK-specific error. See code and maio's documentation for more details.
101 Maio does not have an ad available.
102 Invalid server parameters (e.g. missing Placement ID).
103 Context used to load an ad was not an `Activity` instance.
