Challenges
Many problems arose during the development of the application: fighting with the android sdk, getting google play services jar imported correctly, messing up my version control, and working with InteliJ instead of Android Studio. It is kind of hard to look backwards in retrospect to identify the exact problems because most if not all of them were eventually solved. Oh well, it was definitely a very long yet very helpful journey.
