Now that you have the SDK, you need an integrated development environment (IDE) to use it. It's time to download Eclipse!
Downloading the correct version of Eclipse is very important. At this writing, Android supports Eclipse versions Galileo and above. Check the Android System Requirements page at http://developer.android.com/sdk/requirements.html. If you're still unsure, download Eclipse Galileo (version 3.5), that's the version I'm currently using. When you download the file, you'll probably need to find the Older Versions link on the download page and select the latest Galileo version.
To download the correct version, navigate to the Eclipse downloads page (www.eclipse.org/downloads), select Eclipse IDE for Java Developers. Eclipse IDE for JAVA EE Developers works as well.
Eclipse is a self-contained executable file; after you unzip it, the program is installed. Even though you could stop here, I suggest pinning a shortcut to your Start menu if you're on Windows so that Eclipse is easy to find when you need it.
To install Eclipse, you need to extract the contents of the Eclipse .zip file to the location of your choice. For this example, I use C:\Program Files\Eclipse when on Windows. For OS X users, unzip the .gz file and simply drag the application into your applications folder.
