I DO need your help.I followed this steps for installing ADT 22.0.5 . this step is declared in developer.android.google.com for installing ADT:

4.In the Add Repository dialog, click Archive.

5.Select the downloaded ADT-22.0.5.zip file and click OK.

6.Enter "ADT Plugin" for the name and click OK.

7.In the Available Software dialog, select the checkbox next to Developer Tools and click Next.

8.In the next window, you'll see a list of the tools to be downloaded. Click Next.

9.Read and accept the license agreements, then click Finish.

10.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.

Answer 1

This is due to lower version of the Eclipse.

In Eclipse Help -> Install New Software

Add this Url https://dl-ssl.google.com/android/eclipse/

Answer 2

I had this error and was not able to overcome it without downloading ADT again and installing/extracting it again. I think that will be the fastest coarse of action for anyone experiencing this. Fortunately, the new ADT has the updates already applied.

In my case, I extracted ADT on top of my existing install. This kept my existing non-standard extensions in place, which was nice. There could be adverse side effects to doing this though. So, I would only recommend it if you are prepared to identify and deal with any oddities that come up.
