更新android sdk出現 A folder failed to be renamed or moved

在啟動並執行過程中提示錯誤

-= 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 ‘D:\training\android\android-sdk_r06-windows\android-sdk-windows\tools’.
When ready, press YES to try again.

解決方案：
關閉SDK Setup.exe。先備份tool檔案夾。然後將temp檔案夾下的tools開頭的檔案夾下的全部檔案複製到tools下。
重新運行SDK Setup.exe。會彈出下面視窗

點擊install可以正常安裝

注意你可以通過 Avaliable Packages 安裝只需要的包。如果你的網速不快可以嘗試離線安裝（網上有相關文章介紹）。
