I wrote a blog about open sourcing the first android application I ever made when I started to learn mobile development. The idea behind the app was that I wanted a way to store all the WiFi passwords from coffee shops in my city so that I could always connect to a network if I needed it while I was out. The app is still functioning and has new entries from time to time.
