Update

To do same thing which I described above, you can do same just pressing Ctrl+Alt+O, it will optimize imports of your current file and your entire project depends on your selection in a dialog.

You can do it on the fly. You don't need to call (Ctrl+Shift+O) or "Project/Optimize Imports..." each time.

Just set this checkbox in Settings -> Editor -> General -> Auto Import -> Optimize Imports on the fly.

On OSX: Preferences -> Editor -> General -> Auto Import -> Optimize imports on the fly

Press Ctrl + Alt + O.

A dialog box will appear with a few options. You can choose to have the dialog box not appear again in the future if you wish, setting a default behavior.

Enjoy!!

On Mac use control + option + O

Sorry for the late answer.. For mac users command + option + o Try this.. It is working for me..

Ctrl+Alt+O works pretty well and removes unused imports

there is also an Android Studio (1.4) setting to optimze imports on the fly: see Settings->Editor->General->Auto Import.

I think Ctrl + Alt + O works when the import is unused but a valid import. However, say you try to import a class from a package that does not exist or no longer exists (which can happen during refactoring), the shortcut command does not work (atleast it didn't for me). If you have more than one file like this, things can get problematic.

To solve this problem, click on Analyse -> Inspect code -> (select your module / project). Let it perform the analysis. Go down to Imports -> Unused imports. Click on the "Delete unnecessary import" button that appears on the right.

Press Alt + Enter with the cursor on top of the import. The Optimize imports menu will show. Press Enter again. Your unused imports will be removed.

Since Android Studio 3+, this can be done by open the option "Optimize imports".

Alt+Enter the select "Optimize imports".

This must be enough to removed the unused imports.
