Eclipse Install New Software

After installation is completed, restart Eclipse. When Eclipse restarted, I was supposed to get a window that said “Welcome to Android Development” where the option Use existing SKDs needed to be selected. Then you need to select the directory to where u downloaded the Android SDK. The window did not appear for me. Instead, I went to Window and selected Preferences. 

Eclipse Preferences

(before that, you should install android sdk toot kit by http://developer.android.com/sdk/index.html)

you go to http://developer.android.com/sdk/index.html

Other Download Options

SDK Tools Only

If you prefer to use a different IDE or run the tools from the command line or with build scripts, you can instead download the stand-alone Android SDK Tools. These packages provide the basic SDK tools for app development, without an IDE. Also see the SDK tools release notes.
