Android SDK location should not contain whitespace, as this cause problems with NDK tools

解决方案一：
The easiest solution is to move the SDK somewhere else, where there is no space or other whitespace character in the path, such as C:\Android\sdk. You can point both Android Studio installations to the new location.
解决方案二：
just change the path:

"c:\program files\android\sdk" to "c:\progra~1\android\sdk"
or
"c:\program files (x86)\android\sdk" to "c:\progra~2\android\sdk"
note that the paths should not contain spaces.
解决方案三：
There is another way:

Open up CMD (as Administrator)
Type: mklink /J C:\Program-Files "C:\Program Files" (Or in my case mklink /J C:\Program-Files-(x86) "C:\Program Files (x86)")
Hit enter
Magic happens! (Check your C drive)
Now you can point to C:\Program-Files (C:\Program-Files-(x86)).

最终采用方案三解决问题，最省力气。
