However it still didn't work because it complains about conflicting packages Ubuntu In the end the only solution is to completely apt-get remove eclipse, and download it from the eclipse website.
Then everything works properly. I just upticked cause everybody else did For those wondering: once you add the link, you can just switch to the ADT link and you should be able to get the components to install without manually installing anything from the Eclipse link — Cameron.

I encountered the same problem in eclipse 3. So thanks. And for the Juno- version : You just have to add it - not to install anything. David Fraser. Bob Housedorf. Just Russell. Jatinder Bal. Setyo N. Give any name in name field say ADT.
In that case u have required wst packages installed. Or not Android developer For those using eclipse 3. Nelson Patricio Jimenez. About the CSIF. Android SDK in Eclipse. Hadoop Setup.

Our philosophy is that it is the model itself that should decide if there would be a delay or a separate thread required to reconcile itself. For small and fast models, there is no need to do this on a separate thread and the user's experience will appear much more responsive.
For other cases a longer time may be required, but when handled correctly, the model can still give immediate feedback to the user that a longer operation is in progress. A structured document implements the core runtime's IAdaptable interface allowing clients to associate their own data with the document, independent of the implementation. A structured document allows regions of the text to be set as "read-only" so that users can not simply type over something that is intended to remain as part of the document.
The main constraint on what types of languages are appropriate for structured documents and structured regions is whether or not it has the concept of having a syntactically determined end. This is used to know how to correctly handle reparsing deciding what is a "safe start" and "safe end" for the reparse operation. They must be able to handle any text legal or not and must return regions that completely cover the input text for example, whitespace can not simply be ignored.
More difficult to implement, another constraint is that for any correctly specified subset of text, the reparser must give the same results that the parser would if parsed from top to bottom. It might be useful to note, for anyone looking at detail at the parsers and re-parser implementations, for cases involving "invalid input", heuristics are often used to make these decisions so sometimes we can and do "guess right" based on what a user might be in the process of typing and sometimes not -- in other words, its not always easily predictable as it is for "clean" text but is based on doing a reasonable job which would not invalidate subsequent reparsing.
Structured models are mostly interesting due to is extended types and implementers and exists as an abstraction to provide a consistent way to manage shared models and also to access its underlying structured document. In addition to IAdaptable and whole model state listeners, many "Node" structures in SSE related models make use of a finer level of adaption and notification.
This mechanism can be used to have improved UI updates or can be used to keep related models "in synch" for example, a DOM model change can cause a change in an EMF model, and vis versa. Another important contribution of sse. Its purpose is to provide a StructuredModel, appropriate to contentType, that can be shared between many clients at runtime.
This increases efficiency since each client doesn't have to re create their own, but just as importantly, it is an easy way for clients to all stay "in synch"--a change in the model made by one client will be known by all others clients. The other motivation for this is it allows looser coupling, since clients who may not even know about each other can share the resource model without passing it around to each other.
