Question

在我的代码中，调用FileConnection方法（open，create，mkdir，delete）;因此，在启动应用程序时，有问题要求应用程序想要从设备读取文件。所以我搜索了我正在使用的手机，如果有签名应用程序的证书，那么我在Java目录下找到了这些证书。以下列出了“受信任的证书”：

我可以使用其中一个吗？如果是这样我该怎么用呢？

Answer 1

这些是您设备上安装的证书颁发机构的根证书。您需要使用来自这些机构的代码签名证书对您的代码进行签名。以下是verisign http://www.verisign.com/code-signing/sun-java/index.html

我可以将这些证书与FileConnection一起使用吗？
