AdMob

AdMob flutter guide for Custom Adapter (GMA SDK).

Prerequisites

Performed by: Developer

App prerequisites

  • minSdkVersion of 24 or higher
  • iOS 15.0 or higher (platform :ios, '15.0' in your Podfile)
  • The Google Mobile Ads (GMA) SDK must be integrated in your app
  • An ad unit must already be in place which will be used for targeting

Install the SDK

Performed by: Developer

Ensure your android/build.gradle (project-level) includes the required repositories:

allprojects {
    repositories {
        google()
        mavenCentral()
        maven { url 'https://jitpack.io' }
    }
}

Note: On Gradle 7+, use Gradle Setup (Gradle 7+) instead - declare repositories in settings.gradle under dependencyResolutionManagement and remove the allprojects block. Use one approach, not both.

Android

Open the pubspec.yaml file.

Find the dependencies block and add:

dependencies:
  tapmind_ads_admob_flutter: ^3.0.1
  google_mobile_ads: ^5.0.0

iOS

Update Pod file as per below:

target 'Runner' do
  use_frameworks! :linkage => :static # Add this line for tapmind adapter

  flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))
  target 'RunnerTests' do
    inherit! :search_paths
  end
end

Open the pubspec.yaml file.

Find the dependencies block and add:

dependencies:
  tapmind_ads_admob_flutter: ^3.0.1
  google_mobile_ads: ^5.0.0

Configure your app

Performed by: Developer

Add your AdMob app ID to AndroidManifest.xml. Omitting this crashes the app on launch with Missing application ID.

<manifest>
  <application>
    <!-- Sample AdMob app ID: ca-app-pub-3940256099942544~3347511713 -->
    <meta-data
        android:name="com.google.android.gms.ads.APPLICATION_ID"
        android:value="YOUR_ADMOB_APP_ID"/>
  </application>
</manifest>

Replace YOUR_ADMOB_APP_ID with your AdMob app ID from the AdMob web interface. While testing, you may use Google's sample app ID shown above.

Add GADApplicationIdentifier to your app's Info.plist, plus the SKAdNetworkItems array for attribution.

<key>GADApplicationIdentifier</key>
<!-- Sample AdMob app ID: ca-app-pub-3940256099942544~1458002511 -->

Replace YOUR_ADMOB_APP_ID with your AdMob app ID from the AdMob web interface.

Include the complete SKAdNetworkItems list as published by Google - keep this snippet as your single source of truth so it never drifts between pages.

Configure AdMob

Performed by: Ad ops

Create the custom event (waterfall): Mediation → Create mediation group → select Android or iOS and ad format → name it (provided by your account manager) → Add ad units → select your app and ad units.

Add the ad source: Waterfall source → Set up ad source → Custom event → select your app/platform → select the ad unit, then enter:

Android

Mapping name : provided by your account manager
eCPM         : provided by your account manager
Class        : com.tapmind.mediation.TapMindAdmobAdapter
Parameter    : {"placementName": "provided by your account manager"}

iOS

Mapping name : provided by your account manager
eCPM         : provided by your account manager
Class        : TapMindMediationAdapterAdmob
Parameter    : {"placementName": "provided by your account manager"}

The placementName value is case-sensitive and must exactly match the Placement Name configured in the TapMind Dashboard.

Note: Official Google documentation: Create a custom event

Verify integration

Performed by: Developer

After install and dashboard configuration:

  1. Run your app in a debug build. TapMind's test mode is enabled automatically in debug builds and serves test ads at a high fill rate.
  2. Request an ad through your mediation SDK as you normally would.
  3. Confirm a TapMind ad fills. Check logs for the tag TapMindAdapter.
  4. When verified, build in release mode for production - test mode is disabled automatically in release builds, and live ads serve.

Note: Test mode is automatic. It follows your build type: debug = test ads, release = live ads. There is no flag to enable or disable, and nothing to turn off before going live.

Release build QA: There is currently no documented release-safe test path to validate R8/ProGuard without serving live ads. Consumer ProGuard rules from the TapMind AAR are applied automatically when you integrate the published adapter packages.

Troubleshooting

Performed by: Developer

Before diving into logs, confirm adapter class names and the LevelPlay network key against the Class & Network Key Registry, and placementName and eCPM/rate with your account manager.

See Troubleshooting for common symptoms, mediation-specific fixes, release vs debug guidance, and escalation steps. Partner-specific verification steps are under Verify integration above.
