Eclipse is by far the best tool right now to use but you should keep an eye on android studio because even though it is still a work in progress it looks like it will be a very promising IDE and similar to eclipse in many ways. http://developer.android.com/sdk/installing/studio.html
@bCubed I'm gone be cruel but you been living under rock. Eclipse lost profesional developers support+interest+appeal over last 2 years because of the never ending issues with Maven support and proper application testing and people slowly moved to IntelliJ.
Android Studio is gone be nothing like Eclipse, because Android Studio is based on open source version of IntelliJ. On top of that Android Studio is designed with Gradle as top priority
