Resumo: O sistema deverá trabalhar off line com sincronização de dados com base de dados na web sempre que houver conectividade. A ideia é que mesmo que não esteja aberto na tela, a app esteja sempre funcionando em background. O sistema consiste em mostrar no mapa pontos que o utilizador do app deverá visitar, para cada visita há alguns procedimentos a serem realizados, dados a inseri/atualizar/excluir/upload de imagens. O sistema deverá obter localização (lat + lng) de minuto em minuto(s), mesmo que a app esteja em background. Será necessário sempre que conseguir sincronizar as bases de dados, verificar se há notificações a mostrar ao usuário, mesmo que o app não esteja "aberto" no celular. Detalhar 100% ficaria inviável, para isso precisamos marcar reunião.

Hi, we have read all the requirements and we are very confident to do this project from start till end. We definitely have some questions when we discuss project with you. Due to the change of bid system at freelancer.com, they ask freelancer to submit the project proposal at the time of bid. But it is not the right way, initially we can go through the requirements but we definitely need to spend time to write the proposal. Also they provide no place or private message unless you contact us, therefore we cannot submit the portfolio, examples site and our creative work. Also we do not post the portfolio and work examples publically to avoid other people copying it and claiming as their own. Please check our profile and the reviews given by the clients who have worked with us and see how much they appreciate our work by giving us their wonderful word in shape of feedback. Please send us a message so we can submit the links of our portfolio and then you can review and if you like we can start discussing project to help you to reach the final decision. We shall finish this project in timely manner and will finish it in time. We offer IT, Web design, web development and Smart phone application development. We also give life time guarantee to our work. Thanks
