以下是我对ReadMessages类所做的一些更改，但新消息通知仍需要30-45秒。
Service.getInstance().S.CNMI_EMULATOR_INTERVAL = 2; Service.getInstance().S.WATCHDOG_INTERVAL = 3;
我最小化了应用程序检查是否有新消息并将其设置为2的时间段。
对代码或建议的任何更改将不胜感激。
以下是ReadMessages类。

为了考虑实施IInboundMessageNotification的通知的接收速度，
不要忘了很多，取决于您的物理环境，设备和运营商的服务质量。
我有时也会遇到高达20到30秒的等待时间，并且在高质量的载体上有良好的接收效果。
您是否尝试在USB Dongle中使用自己手机中的SIM卡并比较接收时间？ 如果您的手机具有相同的接收速度，请不要让您的希望更好。
org.smslib.Settings类中的标准轮询间隔已经在200毫秒内非常严格地定义。
public int SERIAL_POLLING_INTERVAL = 200;
如果你仍然想要搞乱设置，你可以考虑在调用 Service.getInstance().startService() 之前设置常量
Service.getInstance().S.CNMI_EMULATOR_INTERVAL = 2;
Service.getInstance().S.WATCHDOG_INTERVAL = 3;
另外，尝试使用setter setSettings(Settings settings)来做这些事情，
我正在使用smslib v3.5.4，Settings S变量在该版本中是私有的。
如果您正在搞乱源代码，您可能无法轻松地将代码升级到包含错误修正的更高版本。
