七牛雲直播SDK之推流端快速開發

前言

七牛雲直播SDK疊代快，但是官方文檔跟不上疊代速度，導緻快速開始這部分文檔的還沒更新，很多被廢棄的類、方法還在文檔中，本文是基于2.3.0版本進行的快速開發，由于是第一次接觸直播，存在着許多不足歡迎批評指正。

官方文檔位址：https://developer.qiniu.com/pili/sdk/3718/PLDroidMediaStreaming-quick-start
官方Demo位址：https://github.com/pili-engineering/PLDroidMediaStreaming
SDK位址：https://github.com/pili-engineering/PLDroidMediaStreaming/tree/master/releases
本文代碼位址：https://github.com/infoSafe/LiveBroadcastDemo

快速開始

建立項目（軟編要求 MinimumSDK API 15 ；硬編要求 MinimumSDK API 18）本文使用的是18
導入SDK，在 app/src/main 目錄下建立 jniLibs 目錄。将檔案導入對應的目錄（如下圖）。

添加 happy-dns 依賴（

compile 'com.qiniu:happy-dns:0.2.8'

）

實作自己的 Application
