android sdk for windows出现A folder failed to be renamed or moved 解决办法

安装过程错误信息如下：

-=Warning !=-
A folder failed to be renamed or 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
Please also close any running,programs that may be accessing the directory
'G:\software\android-sdk-windows\tools'.
When ready,press Yes to try again.

解决方法有两种：

第一种方法(老外研究的方法)：

1.复制 tools目录 为一个新的目录 tools-copy ,此时在android-sdk-windows 目录下有两个目录 tools 和 tools-copy
2.在tools-copy目录运行 android.bat ，这样就可以正常 update all 了
3.重新运行SDK Setup.exe

 

第二种方法（推荐）：

 1.进入sdk的temp文件夹，下载好后会有一个tools_r10-windows.zip(版本号可能会不一样，如r09)
 2.解压此文件,将解压出来的文件覆盖tools中的文件
 3.重新运行SDK Setup.exe

如果报如下的错误 是因为有些资源没有下载下来 而想要下载这些必须的资源则需要上面的那些操作 当下载完毕后下面的这个问题也就自然而然的解决了：
