最近因公司需要在導入Sdk，項目需要導入Mopub 的sdk，下面記錄下導入unity的步驟和導出安卓包和iOS包時遇到的坑和解決方式

1.mopub 導入unity

1.導入mopub 的unity的sdk，是一個unitypackge的包，直接點擊導入即可，注意區別在sdk的版本問題(在寫本文的時候用的sdk版本是5.6的，別用最新版本，因爲在導入最新的Sdk的時候直接報錯，導出安卓包時unity直接崩潰閃退了)，sdk的github鏈接如下：https://github.com/mopub/mopub-unity-sdk/releases/ （注意下5.6的）

2.下好後直接導入unity，導入成功後在unity上面出現

下面介紹下這個這些按鈕，重要的時這個Manager SDKs..(從裏面可以下載一些mopub支持的第三方廣告插件)，有需要就可以下載裏面的第三方sdk，沒有需要就算了。

3.其實到這一步，unity導入Mopub Sdk的初步工作就完成了，下面的步驟是在代碼調用sdk，直接上代碼

(代碼思路就是先完成sdk的初始化，然後在代碼中用代碼導入各種廣告的插件)，然後給每種類型的廣告綁定好各自的回調，是一個代理，直接綁定自己的函數即可，然後提供好外部調用的接口，就可以直接傳入廣告ID，播放廣告了.(代碼條理比較清晰，可以直接用)

特別注意：初始化我寫在Start函數中，只用初始化一次即可。

下面分別介紹各種廣告的啓動和回調

1.Banner廣告（橫幅廣告）

創建橫幅廣告

此方法調用最佳時機爲要展示橫幅廣告的時候。

//第一個參數爲banner的廣告單元ID，第二個參數爲顯示的位置
 MoPub.CreateBanner (bannerAdUnit, MoPubBase.AdPosition.BottomCenter);

展示或者隱藏橫幅廣告

MoPub.ShowBanner (bannerAdUnit, true);   // 展示banner

MoPub.ShowBanner (bannerAdUnit, false);  // 隱藏banner

銷燬橫幅廣告

MoPub.DestroyBanner (bannerAdUnit);

橫幅廣告回調監聽

OnAdLoadedEvent (string adUnitId, string height)//橫幅廣告加載成功時
OnAdFailedEvent (string adUnitId, string errorMsg)//橫幅廣告加載失敗時
OnAdClickedEvent (string adUnitId)//橫幅廣告被點擊時
OnAdExpandedEvent (string adUnitId)//橫幅廣告展開時
OnAdCollapsedEvent (string adUnitId)//橫幅廣告收縮時

2.Interstitial(插屏廣告)

請求插屏廣告

調用的最佳時機爲初始化完成的回調監聽裏。

MoPub.RequestInterstitialAd(interstitialAdUnit);

展示插屏廣告

MoPub.ShowInterstitialAd (interstitialAdUnit);

插屏廣告回調監聽

OnInterstitialLoadedEvent (string adUnitId)//橫幅廣告加載成功時
OnInterstitialFailedEvent (string adUnitId, string errorCode)//橫幅廣告加載失敗時
OnInterstitialDismissedEvent (string adUnitId)//橫幅廣告隱藏時
OnInterstitialExpiredEvent (string adUnitId)//橫幅廣告失效時
OnInterstitialShownEvent (string adUnitId)//橫幅廣告顯示時
OnInterstitialClickedEvent (string adUnitId)//橫幅廣告被點擊時

2 RewardedVideo(激勵視頻)
請求激勵視頻

此方法調用最佳時機在初始化完成回調裏。

MoPub.RequestRewardedVideo(rewardedVideoAdUnit, mediationSettings, keywords, latitude, longitude, customerId);

展示激勵視頻

MoPub.ShowRewardedVideo(rewardedVideoAdUnit);

激勵視頻回調監聽

OnRewardedVideoLoadedEvent (string adUnitId)
OnRewardedVideoFailedEvent (string adUnitId, string errorMsg)
OnRewardedVideoExpiredEvent (string adUnitId)
OnRewardedVideoShownEvent (string adUnitId)
OnRewardedVideoClickedEvent (string adUnitId)
OnRewardedVideoFailedToPlayEvent (string adUnitId, string errorMsg)
OnRewardedVideoReceivedRewardEvent (string adUnitId, string label, float amount)
OnRewardedVideoClosedEvent (string adUnitId)
OnRewardedVideoLeavingApplicationEvent (string adUnitId)

OK了，現在相信你在unity上的配置都已經配置完，並且，已經知道怎麼在unity導入該SDK，那現在我們開始導出安卓apk和iOS的Ipa，注意這個Sdk在手機上才能看到廣告，pc端就不用糾結爲什麼怎麼都看不到廣告了

安卓apk的導出

1.我們先看unity的asset目錄下的Plugins文件夾下的Android文件夾
