在您的网站上，我将创建仅公开您在 Android 应用程序中需要的信息的服务.永远不要传递 SQL 字符串.正如罗宾所说，这是一个重大的安全问题.然后只需在您的应用中使用这些服务.

On your website, I would create services that expose just the information you will need in your Android application. Never pass SQL strings. As Robin said, that's a major security issue. Then just consume these services in your app.
