我尝试使用“sendTextMessage”或“sendMultipartTextMessage”从我自己的应用程序发送短信。对于高于 API 19 (KitKat) 的手机，此消息将保存到已发送文件夹中。然而，在我的 Android 8.0 Oreo 手机上，它没有保存到已发送的项目中。
我创建了一个非常基本的测试应用程序，以便在此处发布。该应用程序将简单地检查权限并在 MainActivity 的 Resume 功能触发时发送文本。这是代码。

如前所述，这不会将消息保存到我的 Android Oreo 手机的发送文件夹中。
根据 Android 文档，这是注定要发生的。
注意：从 Android 4.4（API 级别 19）开始，当且仅当应用程序
未选为默认短信应用，系统自动
将使用此方法发送的消息写入 SMS 提供程序（
默认短信应用程序始终负责将其发送的消息写入
短信提供商）。有关如何表现得默认的信息
SMS 应用程序，请参阅电话。
作为解决方法，我尝试手动保存消息。在 SendSMS 函数的底部，这被注释掉了。但是，运行此代码不会导致异常，但也不会将短信保存到发送文件夹。这在旧手机上也能正常工作。我不确定这是否是一个相关问题。
我在这里错过了什么吗？有人可以帮忙吗？ :)
