android開發步步為營之68:Facebook原生廣告接入總結

         開發應用的目的是干嘛？一方面當然是提供優質服務給用戶，還有一方面最重要的還是須要有盈利。不然誰還有動力花錢花時間去開發app?

我們的應用主攻海外市場，所以主要還是接入國外的廣告提供商。本文就今天剛完畢接入facebook原生廣告功能，介紹一下怎樣接入fb的原生廣告。供大家參考。

         
        第一步：申請接入賬號（須要翻牆）
https://developers.facebook.com/docs/audience-network/getting-started#company_info
https://developers.facebook.com/docs/audience-network?

locale=zh_CN

        第二步：facebook sdk下載
https://developers.facebook.com/docs/android?locale=zh_CN
下載完畢后將AudienceNetwork.jar放入項目中的libs中
        

        第三步：接入參考文檔
        NativeAd單條廣告
https://developers.facebook.com/docs/audience-network/android/native-api?locale=zh_CN
        NativeAdsManager多條廣告
https://developers.facebook.com/docs/audience-network/android/nativeadsmanager?locale=zh_CN
        注意由於facebook原生廣告沒有提供廣告地址（比方app下載地址或者廣告的跳轉地址），須要使用這種方法來觸發廣告的跳轉：
nativeAd.registerViewForInteraction(view); 該方法將廣告跳轉事件傳給自己定義的view

        給出demo：
