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.
