IllegalArgumentException usando el paquete de compatibilidad de panal

Question

Añadido la compatibilidad .jar a mi proyecto (el que usa fragmentos, etc.), pero ahora cada vez que construyo mi aplicación Eclipse lanza el error a continuación.Lo agregué copiando la carpeta .jar en la carpeta libs / y luego usé Agregar frasco ... en las propiedades del proyecto / em> diálogo.¿Estoy haciendo esto bien?

Answer 1

Su proceso descrito es correcto.Sin embargo, las herramientas de construcción de Android creen que lo ha agregado dos veces.¿También lo agregó como un proyecto de biblioteca de Android que su proyecto está haciendo referencia a su proyecto, o algo así?
