In Android, ZXing. jar is used to identify the simplified version of the QR code (simplified configuration and code)

Recently, the company made an OTP token activation product. Because the mobile phone token was activated before, a lot of activation information needs to be entered for activation. After a period of use, it is found that the ease of use is not very strong, consider if you add the QR code scanning function does not greatly increase the ease of use. I found a lot of information on the Internet. If it weren't for too many configurations, or the amount of code was too large, I couldn't just write and streamline it, and finally compress it to the current version. If you have a better version, contact me.
