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

As the warning message states, the SDK location should not contain whitespace.

Your SDK is at C:\Users\Giacomo B\AppData\Local\Android\sdk. There is a whitespace character in Giacomo B.

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.

There is another way:

1. Open up CMD (as Administrator)
2. Type: mklink /J C:\Program-Files "C:\Program Files" (Or in my case mklink /J C:\Program-Files-(x86) "C:\Program Files (x86)")
3. Hit enter
4. Magic happens! (Check your C drive)

Now you can point to C:\Program-Files (C:\Program-Files-(x86)).

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.
