Eu poderia realmente usar alguma ajuda. Estou com problemas para fazer com que meu dispositivo Android Wear reconheça as alterações de dados feitas pela minha atividade executada no meu tablet Android. Sou relativamente novo no Android e muito novo nas APIs do Wear, por isso posso estar perdendo algo completamente óbvio ou trivial sem perceber. Reunimos um projeto de alguns exemplos das páginas de documentos do Android Wear e do exemplo do TwoToasters no github. Eu só quero configurar a comunicação de dados entre os dispositivos para poder editar o código para exibir imagens do meu tablet no meu dispositivo Wear. Por fim, quero poder iniciar / interromper uma apresentação de slides no meu dispositivo Wear do meu tablet, mas devo poder chegar lá sozinho assim que o protocolo de comunicação de dados estiver configurado e funcionando, então estou realmente procurando por ajudar com isso. Aqui esta o meu codigo ate agora:

Tudo "parece" ter sucesso, até onde eu sei, mas o método "onDataChanged" do Toast in the Wear nunca aparece no visor do Wear, o que me faz pensar que não está vendo os dados mudarem por algum motivo. Qualquer ajuda seria muito apreciada!
