    Hi,

    I have a little app for creating QR Barcode offline.
    It is based on the great library Zint.dll.
    It is easy to use and sometimes helpful, if you need to create a QR Code without having an internet access.
    It runs on Windows.

    I don't really know why someone would need to create QR Code on his Android device :sign0137:.

    But i am interested in the routine creating it :)

    Hi Kamac,

    it is not creating a QR Code on the Android device.:eek:
    It creates the QR Code on the Windows desktop.
    If you want to provide your own Android app for downloading from your own homepage via QR Code you have to create a QR image.
    Usually we can create one via internet.
    But sometimes we are travelling - lets say in Germany, working in the hotel during the evening and there is no internet access. (Germany is very underdeveloped in this case :sign0137:).
    Regardless we want to finish our work. Therefor we have this little tool ;)

    The tool is a very simple Delphi prog, based on this library:

    O. I understand. I just wonder how you've made a desktop app with B4A. Or was it B4PPC?

    He has already told you in post #3 that it was written in Delphi!

    Must have missed it :sign0161:

    Yet, it's not supposed to be here i think.


    Althrought it doesn't seem that there are any restrictions in what our creations should be made here :p

    Cool!
    Can't we get a D4A (Delphi for Android - I would buy that in a second!!!) working the same way as B4A (translating to java etc)

    I miss my Delphi! Or even C4A (C# for Android) - an no, Mono won't work (dependencies ...)

    He, he, he ...

    C#?

    ...

    C++ is nicer!


    It would be useless throught because there is NDK for C++ Android development.

    @Delphi

    It's easier as it is. ;)

    It may not be what your app needs but the QuickMark application gives users the ability to create and save QRcode and QuickCode images from several data sources, including user entered free text.

    This....

    And here is the reason, as I know some might wonder why would you need to generate a QR code on your phone. Keep in mind, Airline industries do this all the time for paperless entries.

    Why do I need it? Because in my internal app, I need to generate a digital Business Card based on the sales rep that is using the app so they can send a digital copy to anyone that can read a QR code. I would use NFC, but of course not all phones have NFC.

    Thanks.

    @Johan Schoeman Have you tried my QuiQRun! barcode scanner?
    Code:
    https://play.google.com/store/apps/details?id=com.gorgeousapps.quiqrunfree
    I have read codes up to 25 on my Galaxy S4 (not saying it didn't had any trouble, but hey, since we're measuring... :)

    Yes @Johan Schoeman, this is so weird. I even developped the whole app on my nexus 7 tablet where it worked just fine, but once I put it on the play store, I even can't install it on the nexus because it's 'incompatible'. I thought it had something to do with the nexus not having a 'back' camera. In the app developer console there are no complains either after I added the drawable-hdpi folder. Maybe @Erel can shine some light on this?
