Prerequisites

Flutter plug-in is supported from SDK version 7.2.1.2 for Android & iOS.
Support Flutter 3.0.0+

Add the LevelPlay Mediation plug-in to your project

Pub.dev Integration

There are 2 options of adding the LevelPlay Flutter plug-in to your project, using the pub.dev interface.

Run the Flutter CLI command


flutter pub get unity_levelplay_mediation

Update pubspec.yaml file by adding the

unity_levelplay_mediation

definition to your pubspec.yaml file.


dependencies:  flutter:    sdk: flutter   unity_levelplay_mediation: '>=9.1.0 <9.2.0'

Add Ad Quality SDK

注

As of Flutter Plug-in version 3.1.1, Ad Quality is part of the LevelPlay SDK and is automatically initialized when you implement LevelPlay. Use the following Manual integration steps for builds without LevelPlay integrated or for Flutter Plug-in versions earlier than 3.1.1.


dependencies {    implementation 'com.unity3d.ads-mediation:adquality-sdk:9.3.1'}


pod 'IronSourceAdQualitySDK','9.3.1'

Additional settings for iOS

SKAdNetwork support

To enable the display of ironSource network ads while using SDK 7+, make sure to include the ironSource ad network ID in your app property list file (Info.plist).

Select Info.plist in the Project navigator in Xcode.
Select the Add button (+) beside a key in the property list editor and press Return.
Type the key name SKAdNetworkItems.
In the Type column of the dialog, select Array.
Create a dictionary item and corresponding single sting item.
Enter Key name SKAdNetworkIdentifier, and the key value:
```
su67r6k2v3.skadnetwork
```
You can also add
```
SKAdNetworkIdentifier
```
to your Info.plist with the following code:


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

Use ironSource SKAdNetwork IDs Manager to create code snippet to support ironSource network and mediated network IDs. For more information on editing the property list, refer to the Xcode documentation.

Universal SKAN Reporting

To receive copies of winning install-validation postbacks from all of the demand sources for your advertised app, add the NSAdvertisingAttributionReportEndpoint key in your app's Info.plist.

Select Info.plist in the Project navigator in Xcode
Select the Add button (+) beside a key in the property list editor and press Return
Type the key name NSAdvertisingAttributionReportEndpoint
Choose String from the pop-up menu in the Type column
Type the URL:
```
https://postbacks-is.com/
```

App transport security settings

To ensure uninterrupted support for ad delivery across all mediation networks, it's important to make the following changes in your

info.plist

Add in a dictionary called
```
NSAppTransportSecurity
```
. Make sure you add this dictionary on the Top Level Key.
Inside this dictionary, add a Boolean called
```
NSAllowsArbitraryLoads
```
and set it to YES.
Make sure that your info.plist doesn't contain any other exceptions besides
```
NSAllowsArbitraryLoads
```
, as this might create a conflict.
Find more information on ATS in the Apple documentation.

Additional setup for Android

Play Services Dependencies

Add Play Services Dependencies to your app level build.gradle as follows:


dependencies {   implementation 'com.google.android.gms:play-services-ads-identifier:18.2.0'   implementation 'com.google.android.gms:play-services-appset:16.1.0'}

Android 12 Support

Apps updating their target API level to 31 (Android 12) will need to declare a Google Play services normal permission in the manifest file as follows:


<uses-permission android:name="com.google.android.gms.permission.AD_ID"/>

Read more about Google Advertising ID changes here.

Replace Label on AndroidManifest.xml

To prevent the label-related error on AndroidManifest, do the following:

Add ‘xmls:tools’ to AndroidManifest.xml of your project
Add ‘tools:replace=”android:label”’ to the ‘application’ tag

Initialize LevelPlay SDK

To initialize the LevelPlay SDK, follow these steps:

LevelPlay SDK 8.6.0 and later

Implement callbacks for initialization success and failure.
Define the list of ad formats to initialize in the session.
Create an init request using
```
LevelPlayInitRequest.builder
```
. The builder receives the following parameters:
- Your appKey (mandatory)
- User ID (optional: required if you're using server-to-server callbacks or using Ad Quality user journey)
Call LevelPlay.init and pass the context and init request.


class MyLevelPlayInitListener implements LevelPlayInitListener {    @override    void onInitFailed(LevelPlayInitError error) {	      // Provided when init is failed    }    @override    void onInitSuccess(LevelPlayConfiguration configuration) {	      // Provided when init is successfully executed    }}LevelPlayInitRequest initRequest = LevelPlayInitRequest.builder([APP_KEY])                .withUserId("userId") // required for server-to-server callbacks or Ad Quality user journey (optional otherwise)                .build();LevelPlay.init(initRequest, MyLevelPlayInitListener());

LevelPlay SDK before 8.6.0

Implement callbacks for initialization success and failure.
Define the list of ad formats that require support from legacy LevelPlay API. This should include REWARDED.
Call the LevelPlay.init API using the appKey, ad formats, and user ID if relevant.

Add the user ID as part of the initialization API if you're using server-to-server callbacks to reward your users, or using Ad Quality user journey.


class MyLevelPlayInitListener implements LevelPlayInitListener {  @override  void onInitFailed(LevelPlayInitError error) {	// Provided when init is failed  }  @override  void onInitSuccess(LevelPlayConfiguration configuration) {	// Provided when init is successfully executed  }}// Init the SDK when implementing the Multiple Ad Units Interstitial and Banner APIs, and Rewarded using legacy APIs  List<AdFormat> legacyAdFormats = [AdFormat.REWARDED];LevelPlayInitRequest initRequest = LevelPlayInitRequest.builder([APP_KEY])                .withLegacyAdFormats(legacyAdFormats)                .withUserId("userId") // required for server-to-server callbacks or Ad Quality user journey (optional otherwise)                .build();LevelPlay.init(initRequest, MyLevelPlayInitListener());

LevelPlay Init Listeners

```
onInitSuccess
```
: Triggered when the init completes successfully, and ads can be loaded.
```
onInitFailed
```
: The configuration wasn't received successfully, and ads can't be loaded. The recommended best practice is to try and init the LevelPlay SDK later.

Consider the following best practices:

All APIs called before the init API were not changed and should have remained as is, in terms of functionality and syntax. This includes advanced settings, regulations settings or other APIs related to specific ad format
If initialization fails, you can try and initialize the SDK again. Only after a successful initialization process will you be able to load ads.

Verify your integration

Use the LevelPlay integration test suite to test your app's integration, verify platform setup, and review ads related to your configured networks. To enable the test suite in your app, call the setMetaData API before setting the init:


LevelPlay.setMetaData({'is_test_suite': ['enable']});

After mediation init is completed successfully, launch the test suite by calling the following method (Application Context is required):


LevelPlay.launchTestSuite();

For more details and an implementation example of the LevelPlay integration test suite navigate to this article.

Adapters Debug

Call the following API to enable debug logs of mediated network adapters & SDKs:


LevelPlay.setAdaptersDebug(true);

For Proguard Users Only

If you are using ProGuard with the LevelPlay SDK, you must add the following code to your ProGuard file (Android Studio: proguard-rules.pro or Eclipse: proguard-project.txt):


-keepclassmembers class com.ironsource.sdk.controller.IronSourceWebView$JSInterface {    public *;}-keepclassmembers class * implements android.os.Parcelable {    public static final android.os.Parcelable$Creator *;}-keep public class com.google.android.gms.ads.** {   public *;}-keep class com.ironsource.adapters.** { *;}-keep class com.ironsource.unity.androidbridge.** { *;}-dontwarn com.ironsource.mediationsdk.**-dontwarn com.ironsource.adapters.**-keepattributes JavascriptInterface-keepclassmembers class * {    @android.webkit.JavascriptInterface <methods>;}
