For more information about managing policies for device administration, read the * Device Administration * developer guide.
*A managed profile allows data separation for example for the usage of a * device as a personal and corporate device. The user which provisioning is started from and * the managed profile share a launcher. * *
This intent will typically be sent by a mobile device management application (mdm). * Provisioning adds a managed profile and sets the mdm as the profile owner who has full * control over the profile * *
This intent must contain the extra {@link #EXTRA_PROVISIONING_DEVICE_ADMIN_PACKAGE_NAME}. * *
When managed provisioning has completed, an intent of the type * {@link DeviceAdminReceiver#ACTION_PROFILE_PROVISIONING_COMPLETE} is broadcasted to the * managed profile. * *
If provisioning fails, the managedProfile is removed so the device returns to its * previous state. * *
Input: Nothing.
