Android sdk文件夹下有个.android文件夹，里面的东西有用么，可以删么？
还有platforms等几个文件夹，下面的文件夹从android-14到android-L。这些都有用么，可以删不？

Do not delete the folders in the SDK casually, otherwise you cannot guarantee whether the functions are missing. For files related to each API version, please use SDK manager to manage them.

platforms is the location of the sdk image, which accesses the corresponding idk image file according to APIlevel
