Set List Maker 2.2 and BandHelper 2.2, released today, can use the native Android MIDI framework on Android 6 and above. This should offer smoother connections to USB MIDI interfaces, and offers Bluetooth MIDI on Android for the first time. However, it removes support for RTP (wi-fi) MIDI.
The new framework is not enabled by default, but you can go to Help > Utilities and turn off Use Old MIDI Framework to try it.
