I have a Pirates android app on the store now. https://play.google.com/store/apps/details?id=com.greenrobot.pirates I'd like to put out an update, because people have been complaining in the reviews about a black screen and the app not working. I used Openfeint, Facebook, and an Android billing library that are all outdated. I'd like to remove Openfeint and update the other two libraries. I use Facebook for login. My server is using PHP and MySQL, although you shouldn't have to modify the server code much.

I have a simple program which reads data from a microcontroller board through serial and outputs it as a graph. Its written in processing language (processing.org) which is just simplified java. This program ran fine couple of years ago, however, I recently tried it on my new laptop right now and it gives me compile error regarding the library. My assumption is that its something to do with newer versions of one of the third party library used in the code. I am looking for someone familiar in java; I am attaching the program, please go through it and contact me if you think its something you can do. I just don't have the time necessary to sort out this issue but I am sure someone who does Java programming on day to day basis can solve this pretty quickly. EDIT: since a couple of folks emailed me back asking is processing language different than java? It has the same structure and syntax as Java except that it has some in built libraries which make it more "beginner accessible"...
