Getting java.lang.NoClassDefFoundError when using android-betterpickers library

Whenever I try using a Fragment that utilizes the android-betterpickers library, I get the following error.

I have my projected pointed to the android-betterpickers as a library for my project. Anyone know what may be going on here?

I am just extending one of the classes of android-betterpickers from one of my Fragments, shown below, just not showing the other functions like the onCreateView in the Fragment:

public class Fragment_time_addblock extends Fragment DatePickerDialogHandler {


@Override
public void onDialogDateSet(int reference, int year, int monthOfYear,
        int dayOfMonth) {
    // TODO Auto-generated method stub

}


}

The issue happens ONLY when run on a phone/emulator, but able to compile the project and run it successfully, only when I try to open this Fragment, the app crashes.

enter image description here

What can I try to fix this issue?

hate answering my own question, but i will pen down what i did, not the most elegant solution

I copied the right classes and interfaces from the Library into my own project. The issue I think is something to do with cross dependencies as I am using several libraries that reference some other common libraries.

Bringing the code into my own project also allows me to keep the size of the apk reasonably small.

Check if you have that library exported in Java Build Path > Order and Export tab
