Faced the same problem and success with following steps
- Download the ADT Plugin zip file ADT-21.1.0.zip from http://dl.google.com/android/ADT-21.1.0.zip
- (do not unpack it):
- Start Eclipse, then select Help > Install New Software.
- Click Add, in the top-right corner.
- In the Add Repository dialog, click Archive.
- Select the downloaded ADT-21.1.0.zip file and click OK.
- Enter "ADT Plugin" for the name and click OK.
- In the Available Software dialog, select the checkbox next to Developer Tools and click Next.
- In the next window, you'll see a list of the tools to be downloaded. Click Next.
- Read and accept the license agreements, then click Finish.
- If you get a security warning saying that the authenticity or validity of the software can't be established, click OK.
- When the installation completes, restart Eclipse.

Open Eclipse -> Help -> Check for updates
Eclipse will do the rest. Please make sure to restart Eclipse once the update is done for the changes to take effect.

Go to eclipse > help > Check for updates.
It should list the latest update of adt. If it doesn't work, try this :
go to eclipse > help > Install new software
Click on add
add this url : https://dl-ssl.google.com/android/eclipse/
It will list the updates available- which should ideally be adt 21.1.0 (latest)
install the latest adt and everything should be fine.
