Hi all.

Firstly - Happy New Year!

I developed an app with IAP and uploaded to Google. I set-up the IAP details in Google too. Using a device and a user, I download the app, clicked a button and as I needed, the purchase dialog came up, which I completed. However, at the end of this purchase, I got a Signature Verification Failed, code 1003.

Looking at Google, it seems to be related to using Google In-App testing and that it will not be a problem for real/live apps. Although I am using a live app etc.

Has anyone experience this and maybe can help suggest a way to work around this, maybe with code change etc. I've added my code for the IAP. Additionally, even though Google merchant confirms the purchase, the code is not bringing back confirmation of this, with the variable 'Bought' not being set to a 1. Is there a time delay between purchase and having it available/readable in apps?

+ Code Snippet

rem
rem AGK Application
rem

rem Portrait App
SetDisplayAspect( 0.66 )
SetVirtualResolution (400 ,600)

Global Bought

InAppPurchaseSetTitle ("Buy Me") // Name for alert dialogs etc.
InAppPurchaseAddProductID ("buyme", 0) // IAP product ID you configured through iTunes / Google
InAppPurchaseSetup()

Rem see if bought already !!

If GetInAppPurchaseAvailable(0) = 1 Then Bought = 1


button = createsprite(loadimage("button.png"))
setspriteposition(button,100,100)
setspritescale(button,0.4,0.4)

rem A Wizard Did It!
do

    Print ("In-app purchased : " + Str(Bought))

    if GetPointerReleased() = 1 And GetSpriteHitTest(button, GetPointerX(), GetPointerY()) = 1

        InAppPurchaseActivate(0) // 0 = id of product
        // Wait for user to purchase or cancel prompt
        While GetInAppPurchaseState() = 0
             Sync()
        EndWhile

        If GetInAppPurchaseAvailable(0) = 1

             Bought = 1

        Endif

    endif

 Sync()
loop

Thanks in adavance.

Ian.

Ok, after studying a little more, seems the InAppPurchaseSetKeys() instruction is needed prior to the InAppPurchaseSetup().

The example code in the help doesn't have this, but I guess it's logical when you think about it.

Just need to understand why the code 'If GetInAppPurchaseAvailable(0) = 1 Then Bought = 1' is not being resolved when the app is run and only being set when you attempt to purchase again.

Cheers, Ian.

Think I'm there and to save anyone else having to fiddle about, I've added the code to the codebase libary and below.

I moved GetInAppPurchaseAvailable(0) into the main do/loop, as calling it just the once was not enough, as it can take a few seconds to register, so by repeatedly checking, you do get back what your expecting if the product was bought.

Cheers, Ian.
