About the content

Here is one important question Android developers ask while making apps: "How can I do ________ in Android?" The following are versions of this question that we came across recently: - How can I add radio buttons to my app? - How can I play a sound? - How can I navigate between multiple screens? This course is a collection of such questions and their answers. By the end of this course you will have mastered the ability to implement new Android features by reading a blog or article — this is a critical skill possessed by professional Android developers. As a result, you will also be able to use several User Interface components — like Toggle Buttons, Menus, Grid View and many more — that are central to making functional and delightful Android apps.

  • Kunal Chawla - After obtaining a bachelor’s degree in computer science from the University of Texas at Austin, Kunal worked as a programmer for three years, but then decided to switch gears to education. He taught middle school science, worked with Google on a distance learning initiative, and eventually earned a master’s degree in educational technology from Stanford University before joining Udacity.



Udacity is a for-profit educational organization founded by Sebastian Thrun, David Stavens, and Mike Sokolsky offering massive open online courses (MOOCs). According to Thrun, the origin of the name Udacity comes from the company's desire to be "audacious for you, the student". While it originally focused on offering university-style courses, it now focuses more on vocational courses for professionals.
