updating to Android SDK Tools出现问题解决办法

问题由来

      用 Android SDK Manager 更新 Android SDK Tools 出现以下错误信息：

-= warning! =-

A folder failed to be renamed or moved. On Windows this typically means that a program Is using that Folder

(for example WindowsExplorer or your anti-virus software.)

Please momentarily deactivate your anti-virus software. Please also close any running programs that 

may be accessing the directory F':\android-sdk-working-dir\android-sdk_r04-windows\android-sdk-windows\too!s'.

When ready, press YES to try again.

解决办法

1、 进入sdk\temp文件夹，下载好后会有一个tools_r+版本号-windows.zip 文件 

2、 解压此文件到tools_r20-windows目录下（tools_r20-window 可以随意起名)

3、进入tools_r20-windows文件夹，将tools_r20-windows里文件覆盖掉sdk\tools文件夹中的文件
