==広告が出なくなった時の対応方法==
 +
以下どれかでなおるかも
 +
===広告idを変更===
 +
androidの場合は"設定/google/広告/広告リセット"で広告idをリセットする
 +
iPhoneの場合は"設定/プライバシー/adadvitising identifierをリセット"で広告idをリセットする
 +
===unity-androidのビルドオプションをminifyからNoneへ変更===
 +
UnityのPlayer SettingsのandroidのpublisingSetting/MinifyをProguardからNoneへ
 +
 +
===再度unityadmobプラグインを入れる===
 +
#dllなどが抜けてないか確認
 +
#Assets/PlayserviceResolver/AndroidResolver/ForceResolver
 +
 +
==D8: Program type already present: com.google.unity.ads.Banner$12エラーが出たら==
 +
GoogleMobileAdsのversionを更新したなどででるようであれば、一旦Plugins/AndroidやPlugins/iOSを削除
 +
 +
*mainTemplate.gradleのフォーマットが変わってた。
 +
 +
==アダプティブバナー==

canvasScalerを使ってない場合は、scaleFactorじゃなくて、canvas.transform.localScale.yを使う。

    {
        bannerView.Destroy();
        bannerView = null;
    }
}

呼び出す側 

AdMob admob;
void Start()
{
    admob = new AdMob();
    admob.Init();
    admob.RequestBanner();
}
void OnClickPlay() {
    admob.Destroy();
    admob = null;
    SceneManager.LoadScene ("PlayScene");
}

広告が出なくなった時の対応方法

以下どれかでなおるかも

広告idを変更

androidの場合は"設定/google/広告/広告リセット"で広告idをリセットする iPhoneの場合は"設定/プライバシー/adadvitising identifierをリセット"で広告idをリセットする

unity-androidのビルドオプションをminifyからNoneへ変更

UnityのPlayer SettingsのandroidのpublisingSetting/MinifyをProguardからNoneへ

再度unityadmobプラグインを入れる

  1. dllなどが抜けてないか確認
  2. Assets/PlayserviceResolver/AndroidResolver/ForceResolver

D8: Program type already present: com.google.unity.ads.Banner$12エラーが出たら

GoogleMobileAdsのversionを更新したなどででるようであれば、一旦Plugins/AndroidやPlugins/iOSを削除

  • mainTemplate.gradleのフォーマットが変わってた。

アダプティブバナー

320x50の横幅いっぱいのようなレイアウト

サンプル 

AdSize adaptiveSize = AdSize.GetCurrentOrientationAnchoredAdaptiveBannerAdSizeWithWidth(AdSize.FullWidth);
bannerView = new BannerView(adUnitId, adaptiveSize, AdPosition.Bottom);
  • AdSize.GetLandscapeAnchoredAdaptiveBannerAdSizeWithWidth（横向き）
  • AdSize.GetPortraitAnchoredAdaptiveBannerAdSizeWithWidth（縦向き）
  • AdSize.GetCurrentOrientationAnchoredAdaptiveBannerAdSizeWithWidth（実行時の向き）

参考：https://developers.google.com/admob/unity/banner/adaptive?hl=ja

広告の高さのサイズを取得

注意：テスト環境でのみ有効で、本番環境では"ADAPTIVE(Clone)"のGameObjectが取得できないので、使えなかった。 

bannerView.OnBannerAdLoaded += () =>
{
	GameObject adaptive = GameObject.Find("ADAPTIVE(Clone)");
	float scale = adaptive.transform.localScale.y;
	float adaptiveAdHeight = scale * bannerView.GetHeightInPixels();
        Debug.Log($"ad loaded height: {adaptiveAdHeight}");
};

出力 

bannerView.GetHeightInPixels()=100 
height=169.1667

参考：https://stackoverflow.com/questions/77169439/get-admob-adaptive-banner-height-on-unity

広告の高さのサイズをfitさせる例

[SerializeField] RectTransform contentImage;
private AdMobBanner admobBanner;
private void RequestAdmobBanner()
{
	admobBanner = new AdMobBanner();
	admobBanner.Init();
	System.Action<float> callback = (float adaptiveAdHeight) =>
	{
		AdjustContentBottom(adaptiveAdHeight);
	};
	admobBanner.RequestAdaptiveBanner(callback);
}
// imageのstretchのbottom更新
private void AdjustContentBottom(float bottom)
{
	if (contentImage != null)
	{
		Vector2 offset = contentImage.offsetMin;
		offset.y = bottom;
		contentImage.offsetMin = offset;
	}
}

AdMobBanner.cs 

public void RequestAdaptiveBanner(System.Action<float> callback = null)
{
	AdSize adaptiveSize = AdSize.GetCurrentOrientationAnchoredAdaptiveBannerAdSizeWithWidth(AdSize.FullWidth);
	bannerView = new BannerView(GetAdUnitId(), adaptiveSize, AdPosition.Bottom);
	bannerView.OnBannerAdLoaded += () =>
	{
		GameObject adaptive = GameObject.Find("ADAPTIVE(Clone)");
		float scale = adaptive.transform.localScale.y;
		adaptiveAdHeight = scale * bannerView.GetHeightInPixels();
		// Debug.Log($"ad loaded height: {adaptiveAdHeight}");
		callback(adaptiveAdHeight);
	};
	bannerView.LoadAd(request);
}

広告の高さのサイズをfitさせる例(LayoutElementの場合)

LayoutElement layoutElement = footAdObj.GetComponent<LayoutElement>();
if (layoutElement != null)
{
	float space = 10f;
	CanvasScaler canvasScaler = canvas.GetComponent<CanvasScaler>();
	float scaleFactor = Mathf.Min(
		Screen.width / canvasScaler.referenceResolution.x,
		Screen.height / canvasScaler.referenceResolution.y
	);
        layoutElement.minHeight = adaptiveAdHeight / scaleFactor + space;
	// Debug.Log("scaleFactor layoutElement.minHeight=" + layoutElement.minHeight);
}

canvasScalerを使ってない場合は、scaleFactorじゃなくて、canvas.transform.localScale.yを使う。
