Using the ADT Bundle
This appendix shows how you can create an Android application using the ADT Bundle. It also explains how to setup an emulator so you can develop, test, debug, and run Android applications even if you do not have a real Android device.
Installing the ADT
If you already have Eclipse on your local machine, you can install the ADT plug-in only and work with your existing Eclipse. However, note that it is easier to install the ADT bundle. If you choose to install the ADT plug-in, information on how to proceed with it can be found here.
To install the ADT Bundle, first download the ADT bundle from this site.
