Android Studio 0.8.6：安装 Android SDK 平台 20 时出错

Question

应用来自Android Studio 0.8.6: Failure [INSTALL_FAILED_OLDER_SDK] 和Android Studio : Failure [INSTALL_FAILED_OLDER_SDK] 的修复程序，我收到错误：

Loading SDK information...

  Downloading SDK Platform Android 4.4W, API 20, revision 1
  Installing SDK Platform Android 4.4W, API 20, revision 1
  Failed to rename directory C:\android-studio\sdk\platforms\android-20 to C:\android-studio\sdk\temp\PlatformPackage.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:\android-studio\sdk\platforms\android-20'.
When ready, press YES to try again.
Note: you  can use --force to override to yes.
[y/n] =>
  Done. Nothing was installed.

我做错了什么，我该如何解决？

您已将项目保存在 SDK 文件夹中。当 SDK 尝试更新时，整个文件夹将被新数据替换。由于项目是在 IDE 中打开的，并且 SDK 正在尝试替换显示此错误的文件夹。将您的项目文件夹复制到其他文件夹中并关闭您当前的项目并尝试更新。
