To set up the ADT Bundle:
Unpack the ZIP file (named adt-bundle-.zip) and save it to an appropriate location, such as a "Development" directory in your home directory.
Open the adt-bundle-/eclipse/ directory and launch Eclipse.
Caution: Do not move any of the files or directories from the adt-bundle- directory. If you move the eclipse/ or sdk/ directory, ADT will not be able to locate the SDK and you'll need to manually update the ADT preferences.
