Restricted Profiles are a feature introduced in Android Jelly Bean 4.3 that enables you to give users of your applications improved control when sharing their tablet.
On Android tablets, users can now create restricted profiles based on the primary user. When users create a restricted profile, they can enable restrictions such as which apps are available to the profile. A new set of APIs in Android 4.3 also allow you to build fine-grain restriction settings for the apps you develop. For example, by using the new APIs, you can allow users to control what type of content is available within your app when running in a restricted profile environment.
