I am new to Android Studio and want to know about shortcuts. In Eclipse we use shift-ctrl-O for importing. In Android Studio we use alt-enter. My ques
Alt+enter is a 'fast solving problems option'. If you try it over class name after writing 'implements XXXX' it will suggest you to autoimplemnt that methods.
The correct shortcut for 'Organice imports' is Ctrl+Alt+O
You can find a really good Android Studio/IntellyJ shortcuts cheatsheet here: IntellyJ shortcut cheatsheet
------Hint-----
Give a try to Live Templates in Android Studio (It's like magic). Just press Ctrl+J
