ADT Plugin Won't Install

Question

I am using Eclipse Indigo on Windows 7 and have repeatedly tried to install the ADT Plugin for android but to no avail. I have tried: using Eclipse 3.6, downloading the .ZIP file, checking for updates and trying again, using the "http" protocol instead of the "https" in the repository. None of them worked.

However, whenever I try to install it, it either freezes at "calculating dependencies and requirements" or says

"Cannot complete the install because one or more required items could not be found. Software being installed: Android Development Tools 16.0.1.v201112150204-238534 (com.android.ide.eclipse.adt.feature.group 16.0.1.v201112150204-238534)"

Someone please help, I desperately need android for my projects.

Answer 1

It seems this issue is due to proxy. Please try to download plugin locally, by link:

dl.google.com/android/ADT-16.0.1.zip

extract zip file. In Eclipse go to help-> install new software-> Select add

Select to local, and browse to your downloaded package. If problem still persists, try without proxy.

Answer 2

Run Eclipse as Administrator, if you're not already.

Answer 3

What package of Eclipse did you download? Perhaps the package you have doesn't include some pre-requisite that ADT needs.See if my answer to this question help solve your problem.

Also, it would help to see more of the failure reason. We know you're trying to install ADT, what's important is what comes after that, the part that tells which requires items can't be found.
