However, prospective students of the Udacity Android Development Nanodegree program still has to take everything with a grain of salt. After all, learning to code is only the first step. Becoming a Google-worthy developer takes talent, hard work, and maybe a lot of experiences. This being said, if your ultimate goal is to work for Google, may be you should check out these Udacity courses. If you are just learning Android development for the sake of learning to program, may be Couriers courses are much better and affordable (Udacity's $200/month versus Coursera 's $49-$79 for an entire course).
I will let you judge for yourself, please see a screenshot of the email below and links to the two Udacity landing pages mentioned.
