How to install Android SDK on Ubuntu?

For my [Ubuntu][1] machine, I downloaded the latest version of Android SDK from [this][2] page. After extracting the downloaded [`.tgz` file](http://dl.google.com/android/android-sdk_r24.4.1-linux.tgz), I was trying to search for [installation instructions][3] and found: >**To get started on Linux:** > >Unpack the .zip file you've downloaded. The SDK files are download separately to a user-specified directory. > >Make a note of the name and location of the SDK directory on your system—you will need to refer to the SDK directory later when using the SDK tools from the command line. What *exactly* are we supposed to do? [1]: http://www.ubuntu.com/ [2]: http://developer.android.com/sdk/index.html#Requirements [3]: http://developer.android.com/sdk/installing/index.html?pkg=tools
