I am not able to access /dev directory in Android 6.0 device without root access(Tried run time permissions also WRITE_EXTERNAL_STORAGE) Using native code to access RS232 serial port(tty) files inside /dev directory and transfer data, but with Android 6.0 I am unable to open the port(permission denied ona ccessing /dev). I do not want to root my device or to create my app as a system app. Is there any other way to achieve this?
