android开发步步为营之68:Facebook原生广告接入总结

         开发应用的目的是干嘛？一方面当然是提供优质服务给用户，还有一方面最重要的还是须要有盈利。不然谁还有动力花钱花时间去开发app?

我们的应用主攻海外市场，所以主要还是接入国外的广告提供商。本文就今天刚完毕接入facebook原生广告功能，介绍一下怎样接入fb的原生广告。供大家參考。

         
        第一步：申请接入账号（须要翻墙）
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下载
https://developers.facebook.com/docs/android?locale=zh_CN
下载完毕后将AudienceNetwork.jar放入项目中的libs中
        

        第三步：接入參考文档
        NativeAd单条广告
https://developers.facebook.com/docs/audience-network/android/native-api?locale=zh_CN
        NativeAdsManager多条广告
https://developers.facebook.com/docs/audience-network/android/nativeadsmanager?locale=zh_CN
        注意由于facebook原生广告没有提供广告地址（比方app下载地址或者广告的跳转地址），须要使用这种方法来触发广告的跳转：
nativeAd.registerViewForInteraction(view); 该方法将广告跳转事件传给自己定义的view

        给出demo：
