Integrate i-mobile with AdMob Mediation

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

The dashboard interface for i-mobile uses Japanese text for its labels, buttons, and descriptions. The screenshots in this guide have not been translated. In this guide's descriptions and instructions however, labels and buttons are translated with their English language equivalents in parentheses.

Prerequisites

Before you continue, verify the following:

Step 1: Set up configurations in i-mobile UI

Sign up or log in to your i-mobile account.

Add your app to the i-mobile dashboard by clicking the サイト／アプリ管理 (Site/Application Management) tab and the button for your app's platform.

Android

iOS

Fill out the form and click the 新規登録 (Sign up) button.

Android

iOS

To create a new Advertising Spot, select your app under the サイト／アプリ管理 (Site/Application Management) tab.

Android

iOS

Navigate to the 広告スポット管理 (Ad Spot Management) tab and click the 新規広告スポット (New Ad Spot) button.

create_ad_spot

Next, fill out the form by providing the 広告スポット名 (Ad Spot name), 広告スポットサイズ (Ad Spot size) and other details. Then, click the 新規登録 (Sign up) button.

new_ad_spot_form

Your new Ad spot is ready. To view its integration details, click the アプリ設定取得 (Get App settings) button.

ad_spot_list

Take note of the パブリッシャーID (Publisher ID), メディアID (Media ID), and スポットID (Spot ID). You'll need these parameters later when configuring i-mobile for mediation in the AdMob UI.

Android

iOS

Update your app-ads.txt

Authorized Sellers for Apps app-ads.txt is an IAB Tech Lab initiative that helps ensure your app ad inventory is only sold through channels you've identified as authorized. To prevent a significant loss in ad revenue, you'll need to implement an app-ads.txt file. If you haven't done so already, set up an app-ads.txt file for your app.

To implement app-ads.txt for i-mobile, see their Frequently Asked Questions.

Step 2: Set up i-mobile demand in AdMob UI

Configure mediation settings for your ad unit

Android

For instructions, see step 2 in the guide for Android.

iOS

For instructions, see step 2 in the guide for iOS.

Step 3: Import the i-mobile SDK and adapter

In your project's root directory, install the Google Mobile Ads SDK for React Native mediation adapter for i-mobile. Complete the following:

  1. Copy the Google Mobile Ads SDK for React Native adapter tar file from the gma-sdk-react-native/adapters/imobile/ directory into your project's local_packages/ directory. If you don't have the adapters folder, see Prerequisites.

    mkdir -p local_packages
cp EXTRACT_DIR/gma-sdk-react-native/adapters/imobile/gma-mediation-imobile-0.1.0.tgz local_packages/

    Replace EXTRACT_DIR with the path to the directory where you extracted the archive.

  2. Install the adapter package using your preferred package manager:

    npm

    npm install ./local_packages/gma-mediation-imobile-0.1.0.tgz

    yarn

    yarn add ./local_packages/gma-mediation-imobile-0.1.0.tgz

  3. If you're building for Android, add the following repository to the build.gradle file in your project's android directory:

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

Step 4: Additional code required

Android

No additional code is required i-mobile integration.

iOS

SKAdNetwork integration

Follow i-mobile's documentation to add the SKAdNetwork identifiers to your project's Info.plist file.

Step 5: Test your implementation

Enable test ads

Make sure you register your test device for AdMob. i-mobile provides test Spot ID, Media ID, and Publisher ID for testing, you can find them here.

Verify test ads

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

Error codes

If the adapter fails to receive an ad from i-mobile, publishers can check the underlying error from the ad response using ResponseInfo under the following classes:

Android
