因為最近有工作需求要在Unity使用fb sdk，才發現目前最新版的sdk7.10.1是有問題的無法使用，所以花了一些時間下載相關版本，目前找到比較好用的版本，是facebook-unity-sdk-7.2.0
下載網址:https://developers.facebook.com/docs/unity/downloads
下載facebook-unity-sdk-7.2.0後解壓縮後於Unity中匯入FacebookSDK後，還是會有錯誤產生，網路上已有解法，以下簡單說明一下
Assets/Facebook/Editor/android/ManifestMod.cs(29,20): error CS0234: The type or namespace name `Unity' does not exist in the namespace `UnityEditor.Facebook'. Are you missing an assembly reference?
因為namespace衝突所造成
請將namespace UnityEditor.FacebookEditor換成另一個名字，網路上是換成Whatever.FacebookEditor, 請尋找專案中所有檔案全部取代成Whatever.FacebookEditor，一共有9個檔案
PS: 若跳出API Update Required請選No Thanks
Assets/Facebook/Editor/android/FacebookAndroidUtil.cs(105,20): error CS0103: The name `EditorPrefs' does not exist in the current context
點擊此錯誤會跳到該行程式碼，顯示可能的修正選using UnityEditor即可
Assets/Facebook/Editor/FacebookPostprocess.cs(54,36): error CS0619: `UnityEditor.PlayerSettings.bundleIdentifier' is obsolete: `Use PlayerSettings.applicationIdentifier instead (UnityUpgradable) -> UnityEditor.PlayerSettings.applicationIdentifier'
由此錯誤可知，將PlayerSettings.bundleIdentifier更換成UnityEditor.PlayerSettings.applicationIdentifier即可
如此一來就可以正常使用fb sdk了
於Facebook Menu中設定你在https://developers.facebook.com中app的檔案名稱和應用程式編號
於Android Build Facebook Settings中點擊Regenerate Android Manifest
將Assets/Plugins/Android/AndroidMaifest.xml中的package換成Unity Build Setting中Player Settings的Package Name
於手機上測試時，請注意手機網路是否有開啟，最近怎麼測試都無法成功，最後才發現是網路問題Orz...
