How to access serial port from Android MM application ?

SE Policy prevents access of serial ports by android application (by default).

 

I added "allow" to untrusted_app.te

allow untrusted_app tty_device:chr_file rw_file_perms;

 

However, still the avc denial message comes up that untrusted_app not permitted to write to tty_device.

 

How can this be resolved ?
