A little earlier this summer, our Michael Fisher was wondering about the state of multi-user support on tablets, and looked into a couple solutions available for iOS and Android users. Especially with tablets, arguably more so than smartphones, the likelihood that they’ll be shared among multiple family members makes having separate settings for each all the more useful. While there’s still no official support for this kind of user switching on the major platforms, it turns out that Android is quite a long way towards seeing that goal realized, with some major revisions for multi-user support already in place.
Probably the most substantial change that’s happened under the radar has been the creation of support for multiple app data directories. That way, every user will have his or her own copy of stored data for any apps on the phone or tablet, extending across everything from saved games to stored bookmarks. In Jelly Bean, this system appears to already be in place, but there’s no way to add or change users; instead, the current user’s app data is permanently configured as the primary data directory.
There are also signs of this coming support in other parts of the OS, like how code for the Android lockscreen now features hooks for “onUserChanged” events.
It may still be some time before everything get fleshed-out and we’re quickly and painlessly jumping between user profiles on Android, but it’s clear that’s where things are heading.
