Android java.lang.NoClassDefFoundError using JODA libraries

I got stuck in about 2 hours over a problem that, in my opinion, is easy to solve. I am creating a custom time collection for the Android platform, and because of the slowness of the standard classes java.util.Calendar and java.util.Date, I decided to use the JODA library.

Unfortunately, I have no experience with "JAR" links (forgive me ... I came from COM and .NET assemblylies world =) ...), but I find out some tips on the Internet, but obviously they seem , wrong ... These are the steps I took to use the library in my project:

  • Download the latest JODA 2.1 library
  • Create the "lib" folder in the project folder
  • Add 'joda-time-2.1.jar' to the 'lib' folder.
  • Add the library "joda-time-2.1.jar" to the build path.
  • Add 'joda-time-2.1-javadoc.jar' and 'joda-time-2.1-sources.jar' to the 'lib' folder
  • Set the indicated libraries as “java source attributes” and “javadoc location” for the library referenced by joda-time-2.1.
  • Use the new library in my code (ehm ehm 'intelli-sense "and the compiler does not generate any errors or warnings)
  • Run debug on a real or virtual device.

When it comes to the next line (the first that uses JODA BTW), debugging stops:

DateTime newDate = new DateTime(2012, 5, 3, 12, 0, 0);

And it returns the following stack trace:
