"How do applications know where to save data to? They write to a well
known directory under XDG_{CACHE,CONFIG,DATA}_HOME, so use that. Count
the logs and other stuff (if that actually does happen) as in use by the
system if it's too hard to do it any other way.
From
https://wiki.ubuntu.com/SecurityTeam/Specifications/ApplicationConfinement:
Applications will always have read access to their install directory
and have write access to directories they own as determined by the XDG
base directory specification. Specifically:
XDG_CACHE_HOME/<APP_PKGNAME>, XDG_RUNTIME_DIR/<APP_PKGNAME>,
XDG_RUNTIME_DIR/confined/<APP_PKGNAME> (for TMPDIR),
XDG_DATA_HOME/<APP_PKGNAME> and XDG_CONFIG_HOME/<APP_PKGNAME>. Apps
can discover these paths using standard APIs and appending the package
name as defined by the 'name' field of the manifest."

Title:
Storage view does not count correctly space used by app
Status in Canonical System Image:
Confirmed
Status in click package in Ubuntu:
Confirmed
Status in ubuntu-system-settings package in Ubuntu:
Confirmed
Bug description:
When going to Settings->About phone -> Storage
Storage used per app count does not include space used by app in
~/.local/<app>/
This makes is hard to determine which app is actually eating all the storage.
It also makes whole list kinda pointless, since we can have easily app
easting 1G or more and never see it in the lis.
Apps like podcast, browser, twitter can easily eat hundreds of MB without
being spotted in the list.
Expected result:
space occupied by all is calculated from the size of application itself, plus
data used by application under ~/.local/<app>/
tested on RTM krillin (stable/bq-aquaris.en/krillin) v22
