I am looking at making use of QR codes in an application of mine.
I did some research / Googling and I found that this library is apparently a good option to use: http://sourceforge.net/p/zbar/news/
But I read there it says that is still needs an application that can read qr codes for it to work?
Is there not a library that just makes use of the camera and then decodes the qr code in the application that is using the library?
ZBar can be installed as a library in the project, and used as any other activity. You can Check:
That's the example of how to use ZBAR to read a QR, in the onActivityResult you can handle the results (in this case the example makes a toast).
You can follow the installation explanation here:
