ne pouvait pas trouver la classe référencée à partir de la méthode android java.lang.NoClassDefFoundError

Je vais appeler pour une catégorie distincte j'ai écrit dans le même paquet que mon MainActivity classe est enregistré. mais quand je lance l'application il me donne java.lang.NoClassDefFoundError. Je ne comprends pas pourquoi une autre classe définie dans un même colis ne peut pas être identifié. J'ai essayé de nombreuses méthodes suggèrent pour java.lang.NoClassDefFoundError, mais pas tous d'entre eux résolu l'erreur.

Mise à JOUR:

Je crois que j'ai trouvé quelle est la cause de l'erreur. C'est les bibliothèques que j'ai utilisé à l'intérieur de la classe de faire des exceptions. Je suis à l'aide d'httpclient-4.2.5.jar, jackson-core-2.2.0.jar, json-lib-2.4-jdk15.jar, json-simple-1.1.1.jar et rt.jar à l'intérieur de ma classe. Existe t'il une méthode que je peux utiliser ces bibliothèques sans causer de l'exception?
