[Bug 1486618] Re: Clear cache and cookies when uninstalling a WebApp

[Peter Bittner]

A more elaborate approach to address this problem is described at
https://lists.launchpad.net/ubuntu-phone/msg14910.html

- When you try to uninstall an app, and you click on the [ Uninstall ] button in Applications, you're taken to a confirmation screen.
- On this confirmation screen place a checkbox (or the like) below the [ Confirm ] button, labelled "Remove application data", unchecked by default.
- There could be some additional small print explaining what this is all about, either immediately or as soon as the checkbox is being checked (preferred). There's plenty space on the confirmation page. At least on the Aquaris E5.
- (In addition, I feel the [ Confirm ] button should say [ Uninstall ] to make it more explicit what's going to happen.)

I know this additional choice clutters the confirmation page a bit, but
... it's for a good purpose.

Title:
  Clear cache and cookies when uninstalling a WebApp

Status in click package in Ubuntu:
  New

Bug description:
  When a WebApp is uninstalled both cache and cookies should be removed
  to ensure a new installation will start from a clean state.

  - Cache: $ rm -r /home/phablet/.cache/<name-of-app>
  - Cookies: $ rm -r /home/phablet/.local/share/<name-of-app>

  This issue has been discussed in "How clear cache and cookies of
  WebApp? (Gmail WebApp)" on the ubuntu-phone mailing list. A possible
  negative side-effect of *not* clearing cookies and cache is described
  in the thread.
