java - 如何使用 Java android 代码发送多条短信？

Question

我正在创建一个能够从 PC 向手机发送短信的程序。无论是使用在线网关还是使用加密狗发送短信都没有关系（但是，你知道，只有当我们使用加密狗时，发件人的原始号码才会出现，不是吗？）。我在互联网上找到的大多数示例都是在 2006-2010 年编写的，它们都使用 JavaMail 和 Java Communication API，而现在几乎没有通信 api，可能是 oracle 放弃了它。

我正在寻找一些最新的并且正在运行的技术。这是我的第一次尝试。我很高兴看到教程。谢谢

在做了几次 Try & Error 之后，我在一年前创建了以下代码，它工作正常。它使用 GSM 调制解调器发送短信。您的 GSM 调制解调器应该连接到您的 Comm 端口。您将需要 Comm.jar 库来运行此代码，您可以从http://llk.media.mit.edu/projects/picdev/software/javaxcomm.zip下载它

我的代码是触发AT 命令的简单程序版本。它只是在 GSM 调制解调器上触发 AT 命令来发送 SMS。
