Check for SDK useless in this situation..

I would suggest you to use little bit of chatgpt because its crazy how its written.. I can appreciate a lot of research and testing probably that you made to write this library and that you share it, but style and code quality is very bad.

@Override
   public void onCharacteristicChanged(@NonNull BluetoothGatt gatt, @NonNull BluetoothGattCharacteristic characteristic, @NonNull byte[] value) {
       if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.TIRAMISU) {
           Set<MidiInputDevice> midiInputDevices = midiInputDevicesMap.get(gatt.getDevice().getAddress());
           if (midiInputDevices != null) {
               for (MidiInputDevice midiInputDevice : midiInputDevices) {
                   ((InternalMidiInputDevice) midiInputDevice).incomingData(value);
               }
           }
       }
   }

   @Override
   public void onCharacteristicChanged(BluetoothGatt gatt, BluetoothGattCharacteristic characteristic) {
       if (Build.VERSION.SDK_INT < Build.VERSION_CODES.TIRAMISU) {
           Set<MidiInputDevice> midiInputDevices = midiInputDevicesMap.get(gatt.getDevice().getAddress());
           if (midiInputDevices != null) {
               for (MidiInputDevice midiInputDevice : midiInputDevices) {
                   ((InternalMidiInputDevice) midiInputDevice).incomingData(characteristic.getValue());
               }
           }
       }
   }
