Android：将数据备份到互联网的最佳方式？

标签： java android database jdbc

将数据备份到外部位置（即Web服务器）的最佳方法是什么？香港专业教育学院调查了sql和电子邮件和文件上传，但这些似乎没有使用Android sdk吗？ （我可能是错的）我试图将短信息备份到互联网上某个地方的数据库，任何人都可以建议这样做吗？据我所知，在Android上无法访问JDBC？

提前感谢。

继承了添加JDBC时出现的错误：

看看SMS-backup-plus，它可能就是你想要的。

答案 1 :(得分：0)

您可以查看Android的Backup Manager。这不一定适用于需求，但会让用户保留他/她的数据以备不时之需。

如果你有一个SQL数据库，你可以通过你需要的任何方法发送文件（例如，上传到你自己的服务器）。

答案 2 :(得分：0)

我不明白为什么你不能使用JDBC。您是否检查了所有权限，以确保您的应用可以使用互联网或其他任何您需要的权限？
