The MIDI Keyboard app uses Google's new MIDI library for Android 6 or higher. That also explains why you have to pick the thing you want to connect to in the dropdown - that's basically what I'm going to have to do as well. I'm going to let users pick what they want to connect to instead of automatically connecting to devices that are correctly detected as a MIDI USB device. I'm going to have to see if I can do the same thing with my existing library for Android devices below 6.
