I have seen from this question that Intellij Idea (Ultimate) comes configured with all Android Studio plugins.
But I reckon Android Studio also comes with a preconfigured Android SDK.
I believe Intellij doesn't come with Android SDK does it ? So should I install Android SDK normally or are there special things to do to make it work nicely with Intellij ?
You need to download and extract the SDK manually.
Make sure you enable android support: File->Settings->Plugins->Android Support
For better workflow I recommend adding the android specific actions to the menu bar:
File->Settings->Appearance & Behaviour -> Menus and Toolbars
