ownCloud's worked pretty well for me the past few months, but v7.0.3 caused all sorts of breakage on Android when accessing WebDAV shares. Switching photo uploads from FolderSync to the ownCloud Android client fixed that, but Keepass2Android still won't open my password archive directly. I can get to it over WebDAV with ES File Explorer and open it read-only in Keepass2Android, but that's a kludge I didn't need with the previous version. I'd downgrade, but the previous version is only available as source and the downloaded .deb for the previous version is gone from /var/cache/apt/archives. Hopefully they'll undo this breakage in 7.0.4.
