Flutter-SDK

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

LevelPlayRewardedAdListener

class LevelPlayRewardedAdListenerClass with LevelPlayRewardedAdListener {
  @override
  void onAdLoaded(LevelPlayAdInfo adInfo) {
    // Provided when the ad is successfully loaded
  }

  @override
  void onAdLoadFailed(LevelPlayAdError error) {
    // Provided when the ad fails to load. Ad Unit information is included
  }

  @override
  void onAdDisplayed(LevelPlayAdInfo adInfo) {
    // Provided when the ad is displayed. This is equivalent to an impression
  }

  @override
  void onAdDisplayFailed(LevelPlayAdError error, LevelPlayAdInfo adInfo) {
    // Provided when the ad fails to be displayed
  }

  @override
  void onAdClicked(LevelPlayAdInfo adInfo) {
    // Provided when the user clicks on the ad
  }

  @override
  void onAdClosed(LevelPlayAdInfo adInfo) {
    // Provided when the ad is closed

  @override
  void onAdInfoChanged(LevelPlayAdInfo adInfo) {
    // Provided when the ad info is updated. Available when another ad has loaded, and includes a higher CPM/Rate
  }

  @override
  void onAdRewarded(LevelPlayReward reward, LevelPlayAdInfo adInfo) {
    // The user completed to watch the video, and should be rewarded. 
    // The reward parameter will include the reward data.
  }

Show Ads Example

LevelPlayRewardedVideo

final LevelPlayRewardedAd _rewardedAd = LevelPlayRewardedAd(adUnitId: [YOUR_AD_UNIT]);

@override
void initState() {
  super.initState();
  _rewardedAd.setListener([YOUR_LISTENER]);
}

void _loadRewarded() {
  _rewardedAd.loadAd();
}

Future<void> _showRewarded() async {
  if (await _rewardedAd.isAdReady()) {
    _rewardedAd.showAd(placement: [YOUR_PLACEMENT]);
  }
}

// Rest of the class

LevelPlayInterstitial

final LevelPlayInterstitialAd _interstitialAd = LevelPlayInterstitialAd(adUnitId: [YOUR_AD_UNIT]);

@override
void initState() {
  super.initState();
  _interstitialAd.setListener([YOUR_LISTENER]);
}

void _loadInterstitial() {
  _interstitialAd.loadAd();
}

Future<void> _showInterstitial() async {
  if (await _interstitialAd.isAdReady()) {
    _interstitialAd.showAd(placement: [YOUR_PLACEMENT]);
  }
}

// Rest of the class

LevelPlayBanner

final _bannerKey = GlobalKey<LevelPlayBannerAdViewState>();
final _adSize = LevelPlayAdSize.BANNER;
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,
      placementName: _placementName,
      onPlatformViewCreated: () {
        _loadAd();
      },
    );
}

LevelPlayNativeAd

LevelPlayNativeAd? _nativeAd;

@override
void initState() {
  super.initState();
  _nativeAd = LevelPlayNativeAd.builder()
      .withPlacementName(_placementName)
      .withListener(this)
      .build();
}

@override
Widget build(BuildContext context) {
  return
    LevelPlayNativeAdView(
      height: _height,
      width: _width,
      nativeAd: _nativeAd,
      templateType: _templateType,
    );
}

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
