The following is the first few sections of a chapter from The Busy Coder's Guide to Android Development, plus headings for the remaining major sections, to give you an idea about the content of the chapter.


Restricted Profiles and UserManager

Android 4.2 introduced the concept of having multiple distinct users of a tablet. Each user would get their own portion of internal and external storage, as if they each had their own tablet.

Android 4.3 extends this a bit further, with the notion of setting up restricted profiles. As the name suggests, a restricted profile is restricted, in terms of what it can do on the device. Some restrictions will be device-wide (e.g., can the user install apps?), and some restrictions will be per-app. You can elect to allow your app to be restricted, where you define the possible ways in which your app can be restricted, and the one setting up the restricted profile can then configure the desired options for some specific profile.

This chapter will explain how users set up these restricted profiles, what you can learn about the device-wide restrictions, and how you can offer your own restrictions for your own app.
