android how to read the serial data

            
Can be simulated on the simulator?
Or how to read with java?
Reply:
I have not used the simulator do not know, but that's not something that should simulate serial come? ?

java can write the application layer, the bottom can be used to achieve
linux c
fd = open (device, permissions);
bytes = read (fd, buf, n);

The corresponding interface passed to java package

Looks quite complicated, I should look at what to write information? ?
