The Android GUI toolkit is quite different from what you get on the PC with regards to application lifetime. Essentially, every screen is a class called Activity and every screen transition is a call to a different Activity. The cool thing about that is that you can also call Activities from

Hi, I remembering reading one of the pdf's for sage when I found this peice of code that turns a number into a list of individual numbers. I can't seem to find this code again. An example of this code would be taking Pi out to 100 sig figs, and get an output of each individual sig fig in a list.
