[SOLUCIONADO]
Hi,

I have a problem testing in-app billing v3.

Everything works fine, I can buy a product, I even receive a paypal charge, but when the purchase ends, the google payments window closes and the app returns to activity main. It doesn't launch the PurchaseCompleted event.

The code I use is based on the forum example, I use an exclusive activity for purchases, and I do not use a class.

Although I have seen in the forum that someone had similar problems, I have not found a solution and I'm not able to solve it.

Can somebody help me?

Thank you very much.

This is the log since the start of the purchase.

Can you post your code? From the look of your log, there seems to be a problem with the purchasecompleted sub signature. I have an app that uses IAP with no problems, so if you post your code I can compare it to mine & see if I can spot the issue.

Hi Colin,

This is the code:

B4X: 
Sub Process_Globals
    'Purchases
    Dim manager As BillingManager3 
    Private key As String = "MIIBIjAN...."

End Sub

Sub Activity_Create(FirstTime As Boolean)

    Activity.LoadLayout("L_compras")
   
    'purchase
    If FirstTime Then
        manager.Initialize("manager", key)
        manager.DebugLogging = True
    End If
   
End Sub

Sub Manager_BillingSupported (Supported As Boolean, Message As String)
   
    manager.GetOwnedProducts
   
End Sub

Sub manager_OwnedProducts (Success As Boolean, mapPurchases As Map)
           
    If Success Then
        For Each p As Purchase In mapPurchases.Values
            If p.ProductId = "basic" And p.PurchaseState = p.STATE_PURCHASED Then
                manager.ConsumeProduct(mapPurchases.Get("basic"))
            End If
        Next
    End If
   
End Sub


Sub bt_compra1_click
   
    Dim ProdId As String
    ProdId = "basic"
    manager.requestpayment(ProdId, "inapp", "aaaa basic pack")
   
End Sub

Sub manager_PurchaseCompleted(success As Boolean, mapPurchases As Map)
    If success = True Then
        If mapPurchases.ContainsKey("basic") Then
            Aplica_compra("basic")
            manager.ConsumeProduct(mapPurchases.Get("basic"))
        End If
    End If

End Sub

Sub Aplica_compra(sProducto As String)
   
    If sProducto = "basic" Then
        Main.nCreditos = Main.nCreditos + 1000
        Main.mapINI.Put("Creditos", Main.nCreditos)
    End If
       
End Sub

Sub bt_volver6_click
    Activity.Finish
End Sub

Thank you,
Carmen

OK - there's your problem. The PurchaseCompleted sub has a signature of:
B4X: 
Sub manager_PurchaseCompleted (Success As Boolean, Product As Purchase) ' not Map

So you would need to change your code to:

B4X: 
Sub manager_PurchaseCompleted(Success As Boolean, Product As Purchase)
    If Success Then
        If Product.ProductId = "basic" Then
            Aplica_compra("basic")
            manager.ConsumeProduct(Product)
        EndIf
    EndIf
End Sub

Hint: If you're not sure what the sub signature should be you can have IDE to insert the sub signature in your code for you. Type "Sub" then hit space, then tab & select the object you're wanting the signature for (in this case you would find BillingManager3 in the list). Click on the object & a list of available events will come up for you to select from.

- Colin.

Thank you Colin.

After all this time programming with B4A and had no idea that I could know the sub signature as well.
You have helped me a lot.
Thanks again.
