Android Question QrCOdes Read and Generate

[Humberto]

I´m trying to write an APP the generate Qr Codes and I´m trying to use this two library CRZXing ( Version 2.00) and jhsicezxing1 ( version 1.00)

If I compile using one at the time both work well but when I setup both library I get this error

Seems that both libraries are importing
com/google/zxing/aztec/AztecDetectorResult

You should decide which one you want to use. A or B.

Just my 2cent

 

[Humberto]

But each one do one thing, one read and the other generate the code.

There is a way to disable one for loading this library ?

You cant have the same lib imported more than one time.

In the forum are posted several libs also based on the zxing project. Some of them had both functions, scan and create codes.

Just use the search function in the forum.

I tried this two libraries after tested many solutions posted here, but unfortunately didn´t work together

I use this two solutions that works together and I post the sample project here for someone who need too.

You can also add QRCode.bas to Password Protected QR Codes. It should work too.

In "Qrcode.Bas" I tried to change the "shape" from "s" to "c" ( circle ) and the Qrcode doesn´t appear.

I also tried to change the "back color" and I could not see a change.

In the project that you have posted in post #5 ? I might have stripped out some of the functionality in the "generate password protected qr codes" to make it simple. This should have the complete functionality for amongst others QR Codes (also PDF 417, Aztec Codes, etc)
