[SNMP] NoClassDefFound Error
Bonjour,
Je suis en train de développer une application Android utilisant la librairie SNMP4J (version de SNMP pour Java) afin de controler l'allumage et l'extinction d'une salle de recherche holophonique. Tout se passe bien lorsque j'ai un projet java de base mais lorsque j'injecte mon code dans un projet Android, rien ne va plus.
Voici mon code :
