In Android development there are some folder with files that are generated when the build is run and don't need to be included in our repository since they differ between the developers.
Can I tell the repository to not include and/or stop including the folder tree in the update/delete commands?
Yes. SVN's excellent documentation tells you how.
Assuming you're using TortiseSVN, the instructions are listed at the link above. Excerpt:
In most projects you will have files and folders that should not be subject to version control. These might include files created by the compiler, *.obj, *.lst, maybe an output folder used to store the executable. Whenever you commit changes, TortoiseSVN shows your unversioned files, which fills up the file list in the commit dialog. Of course you can turn off this display, but then you might forget to add a new source file.
The best way to avoid these problems is to add the derived files to the project's ignore list. That way they will never show up in the commit dialog, but genuine unversioned source files will still be flagged up.
If you right click on a single unversioned file, and select the command TortoiseSVN → Add to Ignore List from the context menu, a submenu appears allowing you to select just that file, or all files with the same extension. Both submenus also have a (recursively) equivalent. If you select multiple files, there is no submenu and you can only add those specific files/folders.
If you choose the (recursively) version of the ignore context menu, the item will be ignored not just for the selected folder but all subfolders as well. However this requires SVN clients version 1.8 or higher.
If you want to remove one or more items from the ignore list, right click on those items and select TortoiseSVN → Remove from Ignore List You can also access a folder's svn:ignore property directly. That allows you to specify more general patterns using filename globbing, described in the section below. Read the section called “Project Settings” for more information on setting properties directly. Please be aware that each ignore pattern has to be placed on a separate line. Separating them by spaces does not work.
If you're not using Tortoise, you can look in the SVN-book.red-bean.com documentation.
