Banner Ad Unit’s API

This guide explains how to integrate the LevelPlay APIs using an ad unit ID as a waterfall identifier, to load and display banner ads.

Min supported SDK: 8.2.1

Step 1:  Locate the ad unit ID in the LevelPlay platform

To load and display banner ads, you need to use the ad unit ID available in LevelPlay mediation platform:

1. In your LevelPlay account, navigate to Setup → Ad Units  
2. Copy the Banner’s ad unit ID and integrate it into your code

Step 2: Init the ironSource SDK

To initialize the ironSource SDK, follow these steps:

1. Define the list of ad formats to initialize in the session. This should include all the ad formats that you would like to use in LevelPlay, integrating the ironSource APIs (supported for SDK < 8.1.0). 
2. Implement callbacks for initialization success and failure. 
3. Call LevelPlay init API using the appkey, ad formats, and user ID if relevant.

// Define ad formats which are not part of Multiple Ad Units flow   
LevelPlayAdFormat[] legacyAdFormats = { LevelPlayAdFormat.BANNER, LevelPlayAdFormat.INTERSTITIAL, LevelPlayAdFormat.REWARDED};
// Define new listeners 
LevelPlay.OnInitSuccess += LPInitSuccess;
LevelPlay.OnInitFailed += LPInitFailed;
// Init API 
LevelPlay.Init(appKey,userId, adFormats); 

Ad Formats

• If you want to use the LevelPlay Init API with ironSource banner, interstitial or rewarded APIs (<8.1.0) , activate all ad formats as part of your code. 
• If you plan to use the LevelPlay banner API, it is not required to add LevelPlayAdFormat.BANNER to your adFormats list. 
• For using Test Suite: please add all LevelPlayAdFormats to your adFormats list 

Full adFormat implementation:

LevelPlayAdFormat[] legacyAdFormats = { LevelPlayAdFormat.BANNER, LevelPlayAdFormat.INTERSTITIAL, LevelPlayAdFormat.REWARDED };

 Partial adFormat implementation:

LevelPlayAdFormat[] legacyAdFormats = {LevelPlayAdFormat.INTERSTITIAL, LevelPlayAdFormat.REWARDED };

LevelPlay Init Listeners

• OnInitSuccess – triggered when the init is completed successfully. After you receive this indication, ads can be loaded.
• OnInitFailed – the configuration was not retrieved successfully and ads cannot be loaded. It is recommended to try and init the ironSource SDK later (when internet connection is available, or when the failure reason is resolved)

Step 3: Create and load the banner ad 

Using this LevelPlay API, you’ll be able to load banner ads related to a specific ad unit, as defined in the LevelPlay platform.  

1. Create the ad size follow one of this options
   1. Adaptive ad size that adjusts to the screen width (recommended):
      It will return BANNER or LEADERBOARD according to the device type. Networks that supports adaptive feature (Google, Yandex) will return the a height based on their optimization logic.

      LevelPlayAdSize adSize = LevelPlayAdSize.CreateAdaptiveAdSize();

   2. Adaptive ad size using fixed width ad size:
      This option allows you to set a specific width. Networks that support adaptive- banner feature (Google, Yandex) will return a height based on their optimization logic based on the provided width. All other networks will return the fallback size (either BANNER or LEADERBOARD) according to the width provided.
      

      LevelPlayAdSize adSize = LevelPlayAdSize.CreateAdaptiveAdSize(400);

      
      

   3. Specific banner size:
      This option allows you to set specifically a banner size: BANNER, LARGE, MEDIUM_RECTANGLE. The size will be assigned when creating the banner ad object.
      

      LevelPlayAdSize adSize = LevelPlayAdSize.BANNER;

      
      
      Important! To get the size defined for the adaptive banner, you can use the following APIs:
      getBannerScreenWidth() – returns banner width, based on screen width
      getMaximalAdaptiveHeight(Width) – returns banner height, based on width param   

2. Create the banner ad using the relevant parameters:
   1. Ad Unit ID – mandatory 
   2. LevelPlayAdSize – default value Banner (320X50) 
   3. LevelPlayBannerPosition – mandatory    
   4. Placement – optional, used for reporting 
   5. displayOnLoad (optional) – default true, determine if banner will be automatically available on screen 
3. Implement the banner listeners 
4. Load the banner ad

   // Create banner ad objects, without being displayed on screen 
   LevelPlayAdSize adSize = LevelPlayAdSize.CreateAdaptiveAdSize();
   m_BannerAd = new LevelPlayBannerAd(YOUR_AD_UNIT, adSize, LevelPlayBannerPosition.TopCenter, YOUR_PLACEMENT, false);
   // Define listeners for banner ad obj
   m_BannerAd.OnAdLoaded += BannerOnAdLoadedEvent;
   m_BannerAd.OnAdLoadFailed += BannerOnAdLoadFailedEvent;
   m_BannerAd.OnAdDisplayed += BannerOnAdDisplayedEvent;
   m_BannerAd.OnAdDisplayFailed += BannerOnAdDisplayFailedEvent;
   m_BannerAd.OnAdClicked += BannerOnAdClickedEvent;
   m_BannerAd.OnAdExpanded += BannerOnAdExpandedEvent;
   m_BannerAd.OnAdCollapsed += BannerOnAdCollapsedEvent;
   m_BannerAd.OnAdLeftApplication += BannerOnAdLeftApplicationEvent;
   // Load banner ad
   m_BannerAd.LoadAd();

Listeners

// Ad was loaded successfully 
private void BannerOnAdLoadedEvent(LevelPlayAdInfo adInfo)
{
    Debug.Log("Banner Ad Loaded");
    
    //To get actual banner size(either custom/standard size or adaptive)
    LevelPlayAdSize size = adInfo.adSize;
    int width = size.Width;
    int height = size.Height;
}
// Ad load failed
private void BannerOnAdLoadFailedEvent(LevelPlayAdError error)
{
}
// Indication that banner appeared on screen
private void BannerOnAdDisplayedEvent(LevelPlayAdInfo adInfo)
{
}
// Optional: Indication that banner failed to be displayed - iOS only
private void BannerOnAdDisplayFailedEvent(LevelPlayAdDisplayInfoError error)
{
}
// Banner was clicked 
private void BannerOnAdClickedEvent( LevelPlayAdInfo adInfo)
{
}
// optional: Ad is opened on full screen
private void BannerOnAdExpandedEvent(LevelPlayAdInfo adInfo)
{
}
// optional: Ad was restored to original size 
private void BannerOnAdCollapsedEvent(LevelPlayAdInfo adInfo)
{
}
// User pressed on the ad and was navigated out of the app 
private void BannerOnAdLeftApplicationEvent(LevelPlayAdInfo adInfo)
{
}

Banner additional APIs

Pause and resume banner refresh 

You can pause banner refresh in your code if the refresh value is defined in the LevelPlay platform. Use the following methods to stop the automatic refresh of the banner ad or re-enable it after pausing.  

• PauseAutoRefresh – pauses the auto-refresh of the banner ad.
• ResumeAutoRefresh –  resumes auto-refresh of the banner ad after it has been paused.

// Pause refresh
m_BannerAd.PauseAutoRefresh(); 
// Resume refresh
m_BannerAd.ResumeAutoRefresh(); 

Hide and show banners 

As part of the banner constructor, you can load your banner in the background and share it on screen only when relevant. To control the ad visibility after loading, you can use these APIs: 

• ShowAd – banner will be displayed on screen 
• HideAd – banner will be hidden

// show ad 
m_BannerAd.ShowAd();
// hide ad
m_BannerAd.HideAd();
