Unity LevelPlay
Unity LevelPlay flutter guide for Custom Adapter (GMA SDK).
Prerequisites
Performed by: Developer
- See the Compatibility Matrix for the minimum Android and iOS versions for this package.
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_ironsource_flutter: ^1.0.3
google_mobile_ads: ^5.0.0
Note: AdMob and GAM adapters pin play-services-ads:25.0.0 on Android. AppLovin MAX and Unity LevelPlay adapters use compatible GMA version resolution so Gradle can align with your app.
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_ironsource_flutter: ^1.0.3
google_mobile_ads: ^5.0.0
Configure Unity LevelPlay
Performed by: Ad ops
Create the TapMind network: Monetize → Setup → SDK Networks → Available Networks → Manage Networks → select Custom Adapter → enter network key 15c11cb1d → Enter → Save. The network appears as TapMind.

Set up instances: Setup → Instances → select TapMind Marketplace → Add ad instance → select ad type →
Instance name : provided by your account manager
placementCODE : provided by your account manager
Mediation Group: Select your target mediation group
Rate : provided by your account manager
Note: Enter the rate for each placement - it determines waterfall order. Add one instance per ad format to start.
Verify integration
Performed by: Developer
After install and dashboard configuration:
- 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.
- Request an ad through your mediation SDK as you normally would.
- Confirm a TapMind ad fills. Check logs for the tag
TapMindAdapter. - 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.
