According to: Android Studio: how to update after adding a file?
There is no update option for this on AndroidStudio
In Build -> Build Project there is only an option for Make project .
But I think this parameter will use the update parameter:
File->Synchronize . Or, which is the same thing, Ctrl + Alt + Y or a small circle with an arrow menu button.
Update: This feature is available in the new Android Studio. Thanks Jason.
