Answer 1

Had the same problem. Tried to update through Help > Check for Updates, but was getting an alert message like this:

Contacting software sites has encountered a problem

And after that the update process failed. Googled and found the solution.

You just need to add one line in eclipse.ini, which is located in Eclipse folder. Add this line to the end of the file:

-Djava.net.preferIPv4Stack=true

And after that the update process went normally.

The problem lies in the fact that the upload process goes through IPv6, but the internet service provider supports IPv4.

Answer 2

Go to your eclipse, click on Help -> install new software -> Add... -> type in 'ADT plugin' for name, type in 'https://dl-ssl.google.com/android/eclipse/' for URL, then a couple selections including ADT will show up in the window, click on the things you want to update then click okay, and you will be able to update your ADT.

Answer 3

Just update your Android Developer Toolkit. It's automatically done through the included GUI updater/manager.

Answer 4

Run software updates in Eclipse (Help > Check for Updates) and update the ADT.

Answer 5

First update your Android SDK (it looks like you already did this) Then perform update Eclipse

After the Eclipse is updated, make sure you have the latest Android plugins for Eclipse installed.

Last, in the Android SDK Manager plugin make sure your path to the updated Android SDK is correct.
