Multiple Serial Connections on QGC Android

I am testing out a RTK Base Station supported build on android here at Looking at it seems that how android handles the different serial connections is bit different than on desktop (comments indicate there is a memory leak in the serial code so calling availablePorts() is not done so they stop probing after the first serial port.

Is there a fundamental limitation in android preventing having multiple serial connections? Even if I have the RTK code working is it possible to have a SiK radio and RTK Gps connected to QGC on android?
