I have a question about achartengine. My first question is posted here: 
http://stackoverflow.com/questions/8522639/achartengine-inserting-dates-as-x-values-in

I was also wondering if the code used for the PowerTutor was available via opensource (Tuning Android Applications):

My next question was if you have suggestions for updating applications that aren't on the market. How do we set it up to detect changes and send a message to the device?
