Integrating maio with Mediation

This guide is intended for publishers who want to use the Google Mobile Ads SDK to load and display ads from maio via mediation. 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," and so on.

Step 2: Configure mediation settings for your AdMob ad unit

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

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 maio 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, and then click Add Ad Units.

Associate this mediation group with one or more of your existing AdMob ad units. Then, click Done.

Add maio as an ad source

In the Ad Sources card, select Add Ad Network.

Select maio as the ad network and enter the API ID and API KEY obtained in previous section to set up ANO for maio. Then enter an eCPM value for maio and click Continue.

Enter the Media ID and Zone ID obtained in the previous section and click Done.

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 maio adapter defaults to a reward of type "" (empty string) with a value of 1. The maio SDK does not provide specific reward values for its rewarded video ads.

For more information on setting reward values for AdMob ad units, see Create an ad unit.

Step 3: Import the maio SDK and adapter

Add the following maio Maven repository and implementation dependency with the latest version of the maio SDK in the app-level build.gradle file:

repositories {
        url ""

dependencies {
   implementation ''
   implementation 'com.maio:android-sdk:1.1.7'
   implementation ''

  • Download the latest .aar file of the adapter from Bintray and add it to your project.
