Application that reads data from IOIO microcontroller and creates a new acitivity on click

Question

I am creating an application that reads in data from a IOIO microcontroller board and displays it to the screen after I hit a button. I have two classes, MainActivity, which has the button to hit, and AugiActivity which has all of the IOIO code, and display information.

When I hit the button to start the new activity the app crashes. Any ideas?

I had got a similar exception a few months ago. I found the the solution to my problem here: http://stackoverflow.com/questions/10741287/refering-from-one-android-project-to-another-eclipse. Could you make sure that you built your ioio library correctly? — wraith, Mar 15 '13 at 23:18
The onclick code is in the is MainActivity.xml which I posted. It calls the "call_ioio" method in MainActivity. The ioio library is good. When I run the code in AugiActivity by itself everything works fine. — The Starfox, Mar 15 '13 at 23:58
Ive added the stack trace to the LogCat in the original post. — The Starfox, Mar 16 '13 at 00:17
I see you are getting java.lang.NoClassDefFoundError. Check [these](http://stackoverflow.com/questions/2456562/approach-for-fixing-noclassdeffounderror) [links](http://stackoverflow.com/questions/8678630/noclassdeffounderror-android) for some possible solutions. As I see in those problems they were using some external libraries and faced problem. — Master Chief, Mar 16 '13 at 05:33
Master Chief was correct. Turns out there is a weird bug with Eclipse. Even though I imported the IOIO library files into the project, and it compiled with no errors, they were not properly linking together. After I physically copied the .jar files for the libraries, into the specific /lib folder for the project it ran without issue. — The Starfox, Mar 17 '13 at 00:35
