Download the latest version of the Android SDK from the Android Developers website at http://developer.android.com/sdk/index.html. For Ubuntu, you need the Linux version, which is made available as a TGZ archive file. Unpackage the file in the location where you want the development kit to reside (for example,
/home/matthew). Doing so creates a new directory called
android-sdk-linux_x86. Note where you put this directory; you will need the information later.
