Integrate i-mobile with mediation

This guide shows you how to use the Google Mobile Ads SDK to load and display ads from i-mobile using AdMob 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 an Android 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.

Supported integrations and ad formats

The mediation adapter for i-mobile has the following capabilities:

Integration

Requirements

• Android API level 21 or higher

• Latest Google Mobile Ads SDK

• Complete the mediation Get started guide

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.

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

Note: i-mobile has to approve your registration. Once you are approved, you can create an Advertising Spot.

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

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.

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.

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

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.

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

Configure mediation settings for your ad unit

You need to add i-mobile to the mediation configuration for your ad unit.

First, sign in to 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 i-mobile 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.

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

Add i-mobile as an ad source

Under the Waterfall card in the Ad Sources section, select Add Ad Source. Then select i-mobile.

Select i-mobile and enable the Optimize switch. Enter the Login name and API Password obtained in the previous section to set up ad source optimization for i-mobile. Then enter an eCPM value for i-mobile and click Continue.

Note: You only need to set up ad source optimization once per network.

If you already have a mapping for i-mobile, you can select it. Otherwise, click Add mapping.

Next, enter the Publisher ID, Media ID and Spot ID obtained in the previous section. Then click Done.

Note: Ad source optimization takes a few days to gather enough data to accurately calculate eCPM for a mediation network. In the meantime, the ad source optimization status is PENDING, so you must manually set an eCPM value for the network. Once the eCPM can be calculated, the ad source automatically starts updating the eCPM on your behalf.

Step 3: Import the i-mobile SDK and Adapter

Note: Failure to integrate the compatible i-mobile and Google Mobile Ads SDK versions might lead to build issues.

Android Studio integration (recommended)

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

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

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

dependencies {
    implementation("com.google.android.gms:play-services-ads:23.5.0")
    implementation("com.google.ads.mediation:imobile:2.3.2.0")
}

Manual integration

1. Download the latest version of the i-mobile SDK and extract the android-ad-sdk.aar under the sdk folder and add it to your project.

2. Navigate to the i-mobile adapter artifacts on Google's Maven Repository. Select the latest version, download the i-mobile adapter's .aar file, and add it to your project.

Step 4: Add required code

No additional code is required for i-mobile integration.

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.

Important: Disable test mode for AdMob and i-mobile before releasing your app.

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).

Optional steps

Using native ads

Ad rendering

The i-mobile adapter populates the following Native ads advanced field descriptions for a NativeAd.

Field	Assets always included by i-mobile adapter
Headline
Image
Body
App icon	^1
Call to action
Star rating
Store
Price

¹ For native ads, the i-mobile SDK does not provide an app icon asset. Instead, the i-mobile adapter populates the app icon with a transparent image.

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.getAdapterResponses() under the following classes:

Format	Class name
Banner	com.google.ads.mediation.imobile.IMobileAdapter
Interstitial	com.google.ads.mediation.imobile.IMobileAdapter
Native	com.google.ads.mediation.imobile.IMobileMediationAdapter

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

Error code	Reason
0-99	i-mobile SDK returned an error. See code for more details.
101	i-mobile requires an Activity context to load ads.
102	i-mobile server parameters configured in the AdMob UI are missing/invalid.
103	The requested ad size does not match an i-mobile supported banner size.
104	i-mobile's native ad load success callback returned an empty native ads list.
