Error after updating ADT in eclipse

Question

Last version of ADT in my eclipse was API 16, so I updated ADT (eclipse->Help->Install new software->Work with: ADT ) and then multiple errors occurred!!!

I can not even open Android SDK Manager !

There are some Screenshots from error :

How can I roll it back?!

Ps : Before Updating ADT I tried to add "SQLiteManager" PLugin by copying a jar file into "eclipse/dropins/" folder, but eclipse did not run anymore. So I removed the jar file and eclipsed lunched successfully!

Answer 1

Update your ADT Plugin

open HELP > About Eclipse > Installation Details

And also update Android SDK with 23.0.0

Answer 2

Recently i faced the same problem, it simply fails to update. It was mainly due to a packaging bug of Android. This is a problem many people might face. here is the workaround:

1. Go to Help (in Eclipse)> about Eclipse SDK> Installation details and remove Android Development Tools (ADT).
2. Go to Help (in Eclipse) > install new software > beside the 'work with' box click ''Add'' , type ADT as name and as location give this url: https://dl-ssl.google.com/android/eclipse/
3. Then you will see developer tools, select Android development tools from there and click Finish. this should update your Android Development tools and solves many other consequential issues while updating SDK. So, basically you have to remove your old ADT and then only you can update from Google' repo given in the URL.
