Midi sequencer android porting issue

Hi there, I would like to convert the following midi sequencer to android An error occurred; Failed resolution of: Ljavax/sound/midi/MidiSystem I think something wrong around MidiBus, The sketch never open it's self on my phone. There is someone who could help me?

Thanks a lot! Giammy
