eclipse android sdk update to v20 broke my install

Question

My AVD informed me of an update to v20. But after doing so I cannot use Eclipse for Android development any more.

When I try to use Help -> Check for updates:

and click Next I then get the error shown below. I can't see to find a way to fix this? I'm not verging on uninstalling eclipse and going from the ground up.

    An error occurred while collecting items to be installed
session context was:(profile=epp.package.jee, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).

Answer 2

Go to Window -> Preferences -> Install/Update -> Available Software Sites, find url to ADT Plugin and change https to http (e.g. https://dl-ssl.google.com/android/eclipse/ to http://dl-ssl.google.com/android/eclipse/). When you finalize update operation revert changed url to https. It should help.

Answer 3

There is a hint in this ticket: https://bugs.eclipse.org/bugs/show_bug.cgi?id=290782

Delete all urls from window -> preferences -> Install/Update -> available software sites and retry your update.

Answer 4

As soon as moved eclipse to the c:\ drive everything worked OK. Thanks.

Answer 5

I had a similar problem though I had all the right requirements.

Java 1.6 and 1.7, Eclipse Indigo (v3.7), ADT v18 and SDK 18 (with Android v4.0.3). I wanted to upgrade to v20 ADT and SDK but Eclipse threw the same bug listed above. I upgraded the SDK manually but Eclipse refused to upgrade. I uninstalled ADT v18 in hope that I could install a fresh ADT v20, but to no avail, even with the ADT v20 download from http://developer.android.com/sdk/installing/installing-adt.html.

Finally, I upgraded to Eclipse Juno (v4.2) and everything is working fine.

Answer 6

I think the problem can be solved when you update your Android SDK Tools and Android SDK Platform-tools from revision 19 to revision 20 (using SDK Manager to update). After successful update these tools, you can return to Eclipse and update your ADT plugin.

As it stated here: http://developer.android.com/tools/sdk/eclipse-adt.html

Dependencies:

Java 1.6 or higher is required for ADT 20.0.2. Eclipse Helios (Version 3.6.2) or higher is required for ADT 20.0.2. ADT 20.0.2 is designed for use with SDK Tools r20.0.1. If you haven't already installed SDK Tools r20.0.1 into your SDK, use the Android SDK Manager to do so.

Bug fixes:

Fixed keybindings in various XML editors for Eclipse 4.x. Fixed bug when creating layout configurations that already exist.

Answer 7

Check whether the directory where your Eclipse is in is writable or not. For ex, if it's in Program Files, it is not writable.

If yes, then move Eclipse to a writable location, such as My Documents/Eclipse.
