Cannon is a basic trajectory simulation. You create the target via coordinates and change a variety of variables to try hitting it.

Cannon originated as a graphing calculator program and excluding the calculator this is my first 2D-animated program. That said, don't expect much from it.
Due to the many negative comments and my lack of time to improve the app, Cannon has been restricted to only a few English-speaking countries.

Backstory

This is the timeline of Cannon and my programming experiences from initial creation to release on Android.

~1997: With the help of my dad for the basic trajectory equation, I originally programmed Cannon on my Casio fx-7400G graphing calculator. I eventually added wind, a target, and a fuze.

My 2010 New Years resolution was to extensively learn a programming language by the end of the year, which essentially means decent 2D or basic 3D applications.

April 15, 2010: I began learning Java with an online friend using Eclipse SDK and quickly became hooked to the point of holding off sleep well into the next day on several occasions.

May 1, 2010: I learned Swing (Java GUI) with my project for calculating the value of building purchases in the \'World War\' game for Android/iPhone.

May 6, 2010: I began learning Android development with my other app, Coinflip.

May 15, 2010: Coinflip was my first app to be released on the Android Market.

June 16, 2010: Began working on Cannon for Android and learning 2D animated rendering.

June 27, 2010: Cannon released to the Android Market!
