有log吗，最新版本已经修复了呀。

TonyEasy commented 6 years ago

我是在Activity开启，在onDestory时调用SerialPortManager.getInstance().closeSerialPort();日志是这些， java.lang.NoSuchFieldError: no field with name='mFd' signature='Ljava/io/FileDescriptor;' in class Lcom/kongqw/serialportlibrary/b; at com.kongqw.serialportlibrary.SerialPort.close(Native Method) at com.kongqw.serialportlibrary.b.b(SourceFile:96)

您是如何使用的？导入Library 还是 gradle 导入？ SerialPortManager.java 有改过 FileDescriptor 变量名 mFd 吗

TonyEasy commented 6 years ago

我导入的Library，没有修改这个的变量名，唯一的改动就是改成了单例模式，可以加下我的QQ吗？1245793728请教你一下

kongqw commented 6 years ago

Library， 不排除是您导入的问题或者修改了什么内容，可以先尝试一下gradle 导入，判断下是否是库的问题。

TonyEasy commented 6 years ago

好的 ，我试一下

kongqw commented 6 years ago

@TonyEasy 结果如何？如果gradle导入仍然有问题，请reopen issue

混淆之后，关闭串口也是闪退 ， 报错一样

MarcoJF888 commented 4 years ago

也是关闭串口的时候报错

  if (null != mFd) {
        close();
        mFd = null;
    }

这个close这里
