推荐答案
我用的是USB转串口库，你可以在这里找到:适用于 Android 的 USB 串口.它不需要任何根访问权限.您需要检查您的 Android 设备是否支持 USB 主机模式.然后，使用 USB OTG 电缆和 USB 转串口适配器电缆，您可以开始通过 RS232 与您的串行设备通信.在 USB 转串口库的 Github 页面上有一些代码示例可以帮助您入门.
I use the USB to serial library, you can find it here: USB Serial for Android. It doesn't require any root access. You'll need to check if your Android device supports USB host mode. Then, using a usb OTG cable and a USB to serial adapter cable you can start communicating with your serial device via RS232. There are code examples to get you started on the Github page of the USB to Serial library.
