I lookedin the package andthe classitappears. I found thefollowing solution, but does not work.
NoClassDefFoundError for code in an Java library on Android - Stack Overflow
"

1. Go to "Properties" of the project.
2. Select "Java Build Path"
3. Select "Order and Export" Tab
4. You should see the selected project's "src" and "gen" paths and dependencies here.
5. The order how they listed were first "src" and then "gen" path
6. I switch them, so that "gen" folder is build before the "src"

Thank you
