Android development is probably easiest on Eclipse, but you can use other IDEs too, they just take a little more setup. Have a look at the Developing section in Android developer guide.
Intellij IDEA also has a plugin for Android, but I had trouble using it, and found it easier to just use the Ant build file created by activitycreator tool.

The recommended way to develop an Android application is to use Eclipse with the Android Development Tools (ADT) plugin, provided in the SDK. The ADT plugin provides editing, building,and debugging functionality integrated right into the IDE.
However, if you'd rather develop your application in another IDE, such as IntelliJ, or use Eclipse without the ADT plugin, you can do that instead. The SDK provides the tools you need to set up, build, and debug your application.
