Line とメディエーションを統合する（ベータ版）

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

The dashboard interface for Line 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 Line has the following capabilities:

Integration
Bidding
Waterfall  1
Formats
Banner
Interstitial
Rewarded
Native

1 Waterfall integration is in closed beta, reach out to your account manager to request access.

Requirements

  • Android API level 21 or higher

Step 1: Set up configurations in Line UI

Log in to your Line account.

Add a new application

Click 広告枠管理 (Ad Slot Management) > メディア (Media). Then, click 新規作成 (Create New).

Fill out the form and click 登録 (Register).

Take note of the Application ID.

Create an ad placement

Click the ID of the application you want to add an ad placement. Then, select 詳細 (Detail).

Click スロット 追加 (Add Slot).

Fill out the form and once done, click (登録) Register.

Take note of the Slot ID.

Step 2: Set up Line demand in アド マネージャー UI

Step 3: Import the Line SDK and Adapter

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

dependencies {
    implementation("com.google.android.gms:play-services-ads:23.3.0")
    implementation("com.google.ads.mediation:line:2.8.20240827.0")
}

Manual integration

  1. Download the latest version of the Line SDK's .aar file and add it to your project.

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

Step 4: Add required code

No additional code is required for Line integration.

Step 5: Test your implementation

アド マネージャー。

Line のドキュメント の手順に沿って、LINE テスト広告を有効にします。

テスト広告を確認する

Lineからテスト広告を受信していることを確認するには、広告インスペクタで Line (Waterfall) 広告ソースを使用して単独の広告ソースのテストを有効にします。

Optional steps

Network-specific parameters

The Line adapter supports an additional request parameter which can be passed to the adapter using the LineExtras class. This class constructor includes the following parameters:

enableAdSound
A boolean to specify the default sound start state of banner, interstitial and rewarded ads.

Here's a code example of how to create an ad request that sets these parameters:

Java 

LineExtras lineExtras = new LineExtras(true);
Bundle extras = lineExtras.build();

アド マネージャー広告リクエスト request = new アド マネージャー広告リクエスト.Builder()
   .addNetworkExtrasBundle(LineMediationAdapter.class, extras)
   .build();

Kotlin 

val lineExtras = LineExtras(true)
val extras = lineExtras.build()

val request = アド マネージャー広告リクエスト.Builder()
   .addNetworkExtrasBundle(LineMediationAdapter::class.java, extras)
   .build()

Using native ads

Ad rendering

The Line adapter populates the following fields for a NativeAd.

Field Assets always included by Line adapter
Headline
Image
Body
App icon 1
Call to action
Star rating
Store
Price

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

Error codes

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

com.line.ads
com.google.ads.mediation.line.LineMediationAdapter

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

Error code Domain Reason
1-10 com.five_corp.ad Line SDK returned an SDK-specific error. See Line's documentation for more details.
101 com.google.ads.mediation.line Missing or invalid Application ID.
