Through the above library, you can generate and analyze QR codes in’JAVA MODE’.

However, when you set’ANDROID MODE’,  
No processing due to’BufferedImage’.

Is there any good solution?

I can’t run it from within Android.  
I don’t know how to make it because there is no library.

So, I changed the method for now.

1. Smartphone camera ON
2. TOUCH-Camera OFF
3. Send photo data to server
4. QR code interpretation within the server
5. Sending ‘QR code text’ from the server to the smartphone

The best thing is to interpret it within the smartphone. If there is a good way, please share.
