Detailed off-line installation method of Android SDK

Android SDK has been always very slow to download and sometimes it could make a little bit all night. So only choose to use off-line installation. Now there gives the method.
First, you should download the installation package, android-sdk_r10-windows.zip， to extract the directory, such as my directory: D:\programs\android-sdk-windows. Download address: https://dl.google.com/android/android-sdk_r10-windows.zip
Second, creating the following folders: platforms，docs，samples，usb_driver，market_licensing.
Third, remove all contents from tools. This step is optional, because the contents maybe are outdated, but it may still be available.
