Android平臺上集成海康SDK
以上是我之前寫的一篇Android平臺上集成海康SDK的文章，其中對於Android平臺上集成海康SDK、基於海康SDK進行二次開發基本上進行了詳細地介紹。
這篇文章，在之前的基礎上我對代碼進行了優化和封裝，我們來看，

這個類是已經封裝好的可以直接拿去用的。這裏做幾點說明：
1、代碼中有一處是動態換算通道號。這是因爲在我們業務系統下，我們是在一個Web的設備管理系統中添加上設備，而在這裏添加上的設備的通道號是默認從1開始的，1、2、3、4…這種，所以我們在APP中需要動態換算通道號。我們並沒有在APP中調用海康SDK的接口去獲取通道號。
2、在停止實時預覽和停止遠程回放的方法中，我們並沒有對關閉聲音的結果做判斷。這是因爲我們經過測試發現，關閉聲音可能失敗，但是實時預覽或者遠程回放仍然可以停止，並且有些視頻就是聽不到聲音的，對於是否可以聽聲音，這個國內國外貌似還有不同的政策上的限制，也許是前端設備上的設置導致聽不到聲音並且關閉聲音失敗，具體原因不清楚。
3、在PlayerHikvision中我們沒有寫出切換畫質。其實這個很簡單，這裏就說一下，
切換畫質：
我們在調用live方法時傳入不同的碼流類型即可實現切換畫質，注意：切換畫質只支持實時預覽，不支持遠程回放。
