Android SDK: set-up in IDE

It is a good practice to maintain a Stand Alone version of Android SDK (also called ADT for Eclipse) that is residing on your file system independently of your IDE (Eclipse, or Android Studio).

Getting Android SDK

Open:
http://developer.android.com/sdk/index.html

Download:

http://developer.android.com/sdk/index.html#download

Once you download the SDK (ADT) put it in a convenient location, I keep it on my Mac here:

/Applications/Android/SDK/android-sdk-macosx

The reason for this location is that it is being backed up with all Apps and moved to another Mac when upgrading. We aware that after you download all kinds of versions this folder will grow, mine is about 13 Gb most of that are system-images -- and I don't even have all previous versions of Android downloaded. You will need every version you are building for, so for example I am currently using API 17 and 19.
