You are now a Google Certified Associate Android Developer

Congratulations! You passed all of the requirements for the Associate Android Developer Certification exam!

I recently took a break between terms of Udacity’s Android Developer Nanodegree program so that I could take Google’s Associate Android Developer exam. Finally, the results are in! Pretty happy to pass it on the first try. Queue the emojis! 😜😁

It turns out, Android 9 includes a documented change that requires certs to include a subjectAltName field.
