問題描述
Android Studio 1.5是當前最新Android手機應用開發平台，下載bundle版安裝后，啟動Studio后出現“SDK Manager: failed to install”問題。詳細信息如下：
Android SDK was installed to C:\Users\jack\AppData\Local\Android\sdk
Installing Archives:
Preparing to install archives
Installing SDK Platform Android 6.0, API 23, revision 2
Failed to rename directory C:\Users\jack\AppData\Local\Android\sdk\platforms\android-23 to C:\Users\jack\AppData\Local\Android\sdk\temp\RemotePlatformPkgInfo.old01.
SDK Manager: failed to install
-= Warning ! =-
A folder failed to be moved. On Windows this typically means that a program is using that folder (for example Windows Explorer or your anti-virus software.)
Please momentarily deactivate your anti-virus software or close any running programs that may be accessing the directory 'C:\Users\jack\AppData\Local\Android\sdk\platforms\android-23'.
When ready, press YES to try again.
Note: you can use --force to override to yes.
問題分析
1，網上根據“SDK Manager: failed to install”關鍵詞查了一下，基本都是和以前老版本相關的，不得要領。
2，Studio本身的提示是關閉殺毒程序，其實和殺毒程序無關，仍不得要領。
3，其實問題現象很明顯，是C:\Users\jack\AppData\Local\Android\sdk\temp這個目錄不能寫入，查看此目錄，發現設置了“只讀”屬性。
問題解決
C:\Users\jack\AppData\Local\Android\sdk\temp這個目錄是Andriod Studio安裝程序自建的，安裝程序自己給自己挖了個坑，把SDK下的Temp目錄設為只讀，導致程序啟動更新SDK要寫入Temp目錄時出錯。
將Temp目錄的只讀屬性去掉，Android Studio重啟后SDK更新成功！
