Here's the official spiel:
Android Fundamentals is an online training course featuring Google Developer Advocates Reto Meier, Dan Galpin, and Katherine Kuan, working with the team at Udacity that’s advanced and technical enough for experienced developers who are new to Android (maybe even new to mobile ) but not new to programming.
The course offers step-by-step training in which you’ll build an Android app, and learn best practices of mobile development in general and Android development in particular.
The full course materials (all videos, quizzes, and forums) are available FREE for all students by selecting “View Courseware”. Personalised ongoing feedback and guidance from coaches is also available to anyone who chooses to enroll in Udacity’s guided program.
