I've realized that the Eclipse IDE puts all packages in a project (at least in a Java one) at the same level, e.g.:

packages at same level

However, browsing the file system, you can find that packages are treated in the expected multi-leveled way. Does this have any logical explanation?

This is just a presentation feature. You can click on the little down arrow you see on the left of your screen shot and select Package Presentation -> Hierarchical to have it like your filesystem.

You can see this answer for more information.

  • Certainly it's a hard to find option. Thanks for letting known. Upvoting for that. Didn't yet find a "reasonable reason" for this to be the default view, but since what PSIXO says, as you pointed out, is wrong (I think I remember this view was in eclipse IDE prior to Android), I'm marking yours as accepted answer. – Jorge Antonio Díaz-Benito Mar 12 '13 at 13:34

I asked the same question a couple of times and found the link in above answer helpful in order to change the presentation because it's an option hard to find.

About the Why part, I think it's because of Eclipse being DE-facto standard IDE for Android development and having the packages organized this way is more useful and it forces you to think about a way your classes are organized according to Android project guidelines. It also looks quite like help files on http://developer.android.com/guide to me personally. Also another argument for this might be that in old versions of Eclipse (pre Android time) default view was different.

    The justification of this presentation because of android does not seem right as this presentation has been in Eclipse long before Android. To me, it just a matter of presentation, some likes it some don't : your pick ! The advantage of this presentation is if you have a lot of packages with deep level and not a lot of leafs. – benzonico Mar 12 '13 at 13:21
