Dear, Mr I try read data from usb serial port and it is like (23610). Then convert it to string then split "(" ")" but it crashes. Would you have any idea? image

Not necessarily all bytes arrive in a single message. You should buffer until complete, see https://github.com/mik3y/usb-serial-for-android/wiki/FAQ#When_reading_a_message_why_dont_all_bytes_arrive_at_the_same_time
