问题描述
Android Studio 1.5是当前最新Android手机应用开发平台，下载bundle版安装后，启动Studio后出现“SDK Manager: failed to install”问题。详细信息如下：

Installing SDK Platform Android 6.0, API 23, revision 2
Failed to rename directory C:UsersjackAppDataLocalAndroidsdkplatformsandroid-23 to C:UsersjackAppDataLocalAndroidsdk empRemotePlatformPkgInfo.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:UsersjackAppDataLocalAndroidsdkplatformsandroid-23'.
When ready, press YES to try again.
Note: you can use --force to override to yes.
问题分析
1，网上根据“SDK Manager: failed to install”关键词查了一下，基本都是和以前老版本相关的，不得要领。
2，Studio本身的提示是关闭杀毒程序，其实和杀毒程序无关，仍不得要领。
3，其实问题现象很明显，是C:UsersjackAppDataLocalAndroidsdk emp这个目录不能写入，查看此目录，发现设置了“只读”属性。
问题解决
C:UsersjackAppDataLocalAndroidsdk emp这个目录是Andriod Studio安装程序自建的，安装程序自己给自己挖了个坑，把SDK下的Temp目录设为只读，导致程序启动更新SDK要写入Temp目录时出错。
将Temp目录的只读属性去掉，Android Studio重启后SDK更新成功！
