MobMuPlat android crashing on 'refresh midi devices'

[digitallilllies]

Hi, tapping 'Refresh Midi Devices' from the Audio + Midi menu crashes MobMuPlat when there is a midi device connected, but not when there isn't. i.e. i get 'USBMIDI: Found 0 MIDI device(s)' (and no crash) when there are no devices connected, but the app crashes and i get 'USBMIDI: Found 1 MIDI device(s)' when there is one connected.

Samsung S10+ Android 12 MobMuPlat ver 0.39

Thanks :)

That's the crash. The OS is killing the app because it uses SDK >= 31, but a call to a library to request permission (UsbDeviceWithInfo.requestPermission) is missing a required flag.

i see, is there any way i can resolve this? many thanks :)

No, this needs to be updated in the code, and a new version released.
