In-App Purchase API not giving proper response

[abdul.wahab]

Hi,

I have been facing this issue for the past few days. I have made a sample application to test In-App Purchase API so that I can have an understanding of how the API works. I have created the In-App Id for the available item on the Nokia Store and got it approved. I have followed all the steps in the Java Developer Library. However, every time I try to retrieve the Product Data, I get status value -16 in the productDataReceived method. I have found that value -16 stands for Invalid Product Data which is a Server specific error value. I have not been able to test the In-App Purchase API on both the Nokia emulator and Nokia Asha 303 device.

Please help me and provide some solution to this issue.

Thanks in advance.

Can you please update the time and date of your device to today's date and current time and try again? Can you also software update your Nokia Asha 303 to the latest software? We are aware that some older software versions were giving invalid response codes for the In-App Purchase API. If the problem persists, can you provide the Product ID (either here, or PM me) so that I can look into your issue?

Thanks skalogir

I have updated the device time and date. I am going to update its software. Please tell me how I can PM you.

Do you have any idea why this is not working on the emulator. If I do an in-app purchase simulation on the emulator, it works fine.

You said you got your item approved. What is the current publication state, on Nokia Publish web site for your Product ID? Can it be that for some reason your content has been rejected? In order to check the publication state you need to login to the publisher's web page and select:

Content > Select the Content Item > Select the In-App Purchases Tab > QA Status > "Publication state" should be set to "Published".

Keep in mind that your Product ID is the six digit number that appears under the In-App Purchase Tab that says:
In-app ID

This might be a code related issue. Can you please compile the following code with SDK 1.1 (replace XXXXXX with your Product ID)?

Also ensure that you can access the web from the emulator (visit a random page). If your publication state is set to Published, you can access the internet from the Emulator of the SDK 1.1 and the above code still gives you the code error -16, please PM me and provide your Product ID from Private Messages on this page > Send new message

Don't forget to test on Nokia's server by selecting on Emulator: Tools > In App Purchase Simulation > Application Details > Test with Nokia Publish Server
