Introduction

Widget applications (or simply widgets) are specialized applications useful in providing users with a quick view of specific information from the parent application. Also, widgets allow users to access certain features without launching the parent applications. Combined with the parent application, a widget can have various features to increase the usability of an application set.

To show the changes done by a widget in the UI app, communication between widget and UI app is required. Data sharing can be a way for this type of communication.
