    Nokia Asha IN app purchasing

    Hi I have made two apps for Nokia Asha one is the demo version and I integrated the IAP sdk
    into it successfully the second file is the full version app that the user can purchase it by
    purchasing it through the first app .now that I want to upload both in Nokia ovi store and submit to QA it only have one place
    for uploading jar and jad content files ,so I just wonder where should I place my second full version
    .Do I need to make two profiles one for the full version and the second for the demo version
    with in app purchasing ?!!!
    Or should I redesign and merging the two apps into one (Hope not)
    Can I place the second file as a zip file in (additional documentation )place!!!?

    Please advice and help

    Thanks to all

    You cant have 2 different binaries to be distributed to the same device in the same content item.
    What you need to do is the latter option you mentioned, which is redesign and merge the two app into one and lock all the features that are not part of the demo
    and once the user buys through the in-app purchase the full version then you unlock them.
    Its not that hard to do and I've done so in the past with one of my apps called Package Tracker http://store.ovi.com/content/352191 (hopefully its available in your area as it is not available globally).

    Re: Nokia Asha IN app purchasing

    Hi Shai
    Your app is not available in eastern-Eu ,,,but anyways should I provide the user the password to open the full version
    then how the user who paid can get the password .?!!I don't want to go in that way since it requires preparing lots of passwords
    for each purchasing.
    or do you place a variable in a file then modify it when purchasing!!!this way also is too easy to be cracked and opened .
    could you say what secure method you have used !!!or
    Can I use new profile for demo version so the user can not receive the full version at the beginning and only can get it once he paid .

    thanks

    I use the RMS to store variables on Lock/Unlock status of the app.
    The RMS is completely private and users don't have access to it (unless the entire phone is hacked which is far more harder)
    You should also allow users that have paid for the in-app and deleted the app and installed it again to have an option to re-activate the in-app without re-paying for it and you can do that with the Nokia in-app purchase API.

    Re: Nokia Asha IN app purchasing

    Your welcome,

    Here are my answers:

    1) there is no permission for IAP, however I think that it always good to add javax.microedition.io.Connector.http,javax.microedition.io.Connector.https for Internet use and sometimes I also add javax.microedition.io.Connector.file.write,javax.microedition.io.Connector.file.read if I want to store my vars on both the RMS and the File system to see if they had been tamper with.
    2) Nokia-MIDlet-On-Screen-Keypad: no only works for Nokia Symbian touch devices which prevent them from showing the navigate dpad on the screen for j2me content I don't see how this relate to your app which uses j2me IAP which is only available on Asha devices.
    3) You cant control the IAP orientation AFAIK
    4) Nokia offers free java verified signing for all apps that are submitted to the Nokia store and passes QA (which test the java verified criteria)
