Answer : The problem was with android studio indexing. Follow the steps.. Go to 'File' > 'Invalidate caches/restart' Now the studio will shut down and restart. Now indexing begins. On completion of indexing you will find the Suggestion boxes with every possible suggestions. For me, the problem was that "Show import popup" was not checked at File > Settings > Editor > General > Auto Import > Java.

Answer : 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: 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) ). 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.
