Android Development Tool 23.0.0 and Android L Update error in eclipse [duplicate]

I had the same problem and just solved it. what I did is uninstall entirely the android plugin from eclipse (from the "about" section..) including trace view..

Do not restart eclipse at this point!

then added again the ADT Plugin (https://dl-ssl.google.com/android/eclipse/)

the problem solved!

I guess it's a bug with the SDK manager or ADT Plugin update mechanism..

It saves my day...!

If for some reason you installed an ADT preview and need to revert back to the current stable, you can't use the dialog to install "new" software since what you want is actually an older one. Instead do this:

• Open Help > About Eclipse... on Windows or Linux. On Mac, use theapp's menu > About...
• Click the "Installation Details" button.
• Select the "Installation History" tab.
• Select one of the previous configurations.
• Click the "Revert" button at the bottom.

I am depending on this article How to install plugin for Eclipse from .zipand I made it sorta work. still needs some fix from me. I'll update soon.

This is based on the idea of opening the ADT plugin zip file and copy it's contents by hand , an old fashioned copy-paste method. I still could not yet make it well configured, but the tools do work.

Don't forget to uninstall older ADT before doing this.
