I'm calling for a separate class I have written in same package as my MainActivity class is saved. but when I run the application it gives me java.lang.NoClassDefFoundError. I can't understand why another class defined in same package cannot be identified. I have tried many methods suggest for java.lang.NoClassDefFoundError but not any of them resolved the error.

UPDATE:
I think I found what's causing the error. It's the libraries I used inside the class make that exceptions. I'm using httpclient-4.2.5.jar, jackson-core-2.2.0.jar, json-lib-2.4-jdk15.jar, json-simple-1.1.1.jar and rt.jar inside my class. Is there any method I can use these libraries without causing the exception?

Right Click on your
project -> Build Path -> Configure Build Path -> Order and Export Tab.
Make sure that "Android Private Libraries" is checked for Export.
If you've added any libraries from the libs/ folder, remove them as they are automatically added in the "Android Private Libraries" section.
