Android：将数据备份到互联网的最佳方式？

【问题标题】：Android: Best way to backup data to the internet?Android：将数据备份到互联网的最佳方式？
【发布时间】：2011-07-12 15:58:10
【问题描述】：

将数据备份到外部位置（即 Web 服务器）的最佳方式是什么？我查看了 sql 和电子邮件和文件上传，但这些似乎都不能使用 android sdk 工作？ （我可能是错的）我试图将短信最好备份到互联网上某处的数据库中，任何人都可以提出这样做​​的方法吗？据我所知，Android 上无法访问 JDBC？

提前致谢。

这是我在添加 JDBC 时遇到的错误：

    标签： java android database jdbc


    【解决方案1】：

    看看SMS-backup-plus，它可能就是你想要的。

    【讨论】：

    • 除了上传方法之外，我的所有方法都已准备就绪，我真的不想使用 k9 电子邮件作为电子邮件发送工具。我只是想知道如何连接到 sql 数据库并将项目添加到表中或能够将文件上传到服务器。
    【解决方案2】：

    您可以查看适用于 Android 的 Backup Manager。这不一定会按需工作，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，你可以通过任何你需要的方法发送文件（例如上传到你自己的服务器）。

    【讨论】：

      【解决方案3】：

      我不明白您为什么不能使用 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您可能需要的任何其他内容？
