Connection refused by Android SDK and AVD manager

I am trying 开发者_C百科to set up Eclipse 3.5 with the Android plugin. I followed all the steps and everything installed fine. However, running the SDK and AVD Manager throws a connection refused error. I am behind a firewall at work and can not bypass it.

How can I install the Android platforms without using the manager?

Go to this page: http://developer.android.com/sdk/eclipse-adt.html

Check the Troubleshooting ADT Installation section. You will find the instruction on how to set up a proxy in Eclipse or download the plug-in directly.
