Samsung Mobile SDK Tutorial 4
Welcome to part 4 of my Samsung Mobile SDK Tutorial. In this video I focus on Samsung S Look tools with a specific focus on Samsung WritingBuddy.
Samsung S Look provides specialized widgets like Samsung WritingBuddy, which recognizes hand writing as user input. S Look also provides AirButton which makes it easy to create popup menus. SmartClip allows you to capture and extract Metadata such as text and URLs and to crop screenshots using S-Pen.

Don’t forget to check out the Samsung Smart App Challenge and if it is still November 2013, don’t forget to sign up to win a Samsung Galaxy Note 3, or Samsung Galaxy Gear Smart Watch on my site.
