Unity LevelPlay Flutter Plugin #

A bridge plugin for LevelPlay SDKs.

• LevelPlay Knowledge Center
• Android SDK
• iOS SDK
• Flutter Plugin

Getting Started #

Installation #

flutter pub get unity_levelplay_mediation

Android Configuration #

• The LevelPlay SDK dependency is included in the plugin, so you do not have to add manually to your build.gradle.

Gradle Dependencies Required #

• Play Services dependencies must be added to PROJECT_ROOT/android/app/build.gradle.

// PROJECT_ROOT/android/app/build.gradle
dependencies {
  ...
    implementation 'com.google.android.gms:play-services-appset:16.0.2'
    implementation 'com.google.android.gms:play-services-ads-identifier:18.0.1'
    implementation 'com.google.android.gms:play-services-basement:18.3.0'
}

iOS Configuration #

• The LevelPlay SDK pod is included in the plugin, so you do not have to add it to your Podfile.

SKAdNetwork Support #

Add the SKAN ID of IronSource Network on info.plist

<key>SKAdNetworkItems</key>
<array>
   <dict>
      <key>SKAdNetworkIdentifier</key>
      <string>su67r6k2v3.skadnetwork</string>
   </dict>
</array>

App Transport Security Settings #

Set NSAllowsArbitraryLoads: true on info.plist to allow http as some mediated networks require http calls. (Note: LevelPlay Network calls are all encrypted.)

Note:

• Make sure that your info.plist does not contain other ATS exceptions such as NSAllowsArbitraryLoadsInWebContent.

<key>NSAppTransportSecurity</key>
<dict>
  <key>NSAllowsArbitraryLoads</key>
  <true/>
</dict>

App Tracking Transparency (ATT) Prompt #

TODO: Remove or keep this?

Implement the ATT prompt to request user authorization for app-related data.

• Note: This is not part of LevelPlay SDK but a bridge for AppTrackingTransparency ATTrackingManager.
• You have to add NSUserTrackingUsageDescription to your info.plist if you intend to call this API.

Future<void> checkATT() async {
  final currentStatus = await ATTrackingManager.getTrackingAuthorizationStatus();
  if (currentStatus == ATTStatus.NotDetermined) {
    final returnedStatus = await ATTrackingManager.requestTrackingAuthorization();
    print('ATTStatus returned: $returnedStatus');
  }
  return;
}

General Usage #

Implement Listeners #

final _adUnitId = 'YOUR_AD_UNIT_ID';
final _placementName = 'YOUR_PLACEMENT';

void _loadAd() {
  _bannerKey.currentState?.loadAd();
  // or store LevelPlayBannerAdView in variable and call '_bannerAdView.loadAd();'
}

@override
Widget build(BuildContext context) {
  return
    LevelPlayBannerAdView(
      key: _bannerKey,
      adUnitId: _adUnitId,
      adSize: _adSize,
      listener: this,

  _nativeAd = LevelPlayNativeAd.builder()
      .withPlacementName(_placementName)
      .withListener(this)
      .build();
}

Refer to the example app for the more detailed implementation sample.

Note:

• Make sure to read the official documents at [LevelPlay Knowledge Center](TODO: replace with the real KC link) for proper usage.
• Some configurations must be done before initialization.
• LevelPlayBannerListener is deprecated - Please use LevelPlayBannerAdViewListener with LevelPlayBannerAdView instead.
• LevelPlayInterstitialListener is deprecated - Please use LevelPlayInterstitialAdListener with LevelPlayInterstitialAd instead.

Mediation #

• You can use the LevelPlay's mediation feature by adding adapters/SDKs to your project.
• Some networks require additional configurations.
• Make sure to use the compatible adapter versions.

Android #

Make sure to follow LevelPlay Knowledge Center document for additional setup.

• Add dependencies to YOUR_PROJECT/android/app/build.gradle
• Add required settings to YOUR_PROJECT/android/app/src/main/AndroidManifest.xml

iOS #

Make sure to follow LevelPlay Knowledge Center document for additional setup.

• Add pod dependencies to YOUR_PROJECT/ios/Podfile: target 'Runner'
• Add required settings to YOUR_PROJECT/ios/Runner/info.plist

Note:

• For Podfile, transitive dependencies error will be thrown with use_frameworks!. The workaround is to add the code below to Podfile:

use_frameworks! :linkage => :static
