Serviço da Web WSDL Android ksoap2

Estou tentando conectar-me a um serviço da Web por meio de um dispositivo Android usando a biblioteca ksoap2. Consegui fazê-lo funcionar em dois serviços diferentes, mas agora encontrei um problema. Sempre que passo um objeto em vez de um tipo primitivo, isso gera um erro. Eu implementei as classes usando KvmSerializable e ainda sem sorte. Aqui está o xml da solicitação enviada de um navegador da Web que funciona e o xml da solicitação enviada do dispositivo Android que não funciona. Qualquer sugestão seria ótima!
