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：

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.

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:\Users\jack\AppData\Local\Android\sdk\temp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:\Users\jack\AppData\Local\Android\sdk\temp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！
