Erel when I use this library I have problem with it.
"Sub manager_purchasecompleted signature does not match expected signature"
I checked with real accaunt
I checked my key
But nothing changed...

 

[Erel]

How have you declared this sub?

 

[shaxboz]

Sub Manager_PurchaseCompleted()
    reklama=True
    ImageView12.Visible=False
End Sub

 

[Erel]

The signature is incorrect.
See this thread: http://www.b4x.com/forum/basic4android-getting-started-tutorials/6546-ide-tips.html

You should let the IDE to build the event sub.

Using this lib and this type of billing...
Do I need to use the licence lib? or this is enough to be sure you sell the in-app to only one device?

Draft apps are not allowed any more.
Does this lib adds the BILLING permission to the apk?

Thanks

you do not need to add the lib license, in-app manages all.
You look also THIS

Hi, I need my beta testers not to be billed for the add-ins.
Any way to do it?
Thanks

 

[Erel]

You can add their accounts as test accounts. You can also cancel their transactions.

Testing with a Android 2.2 emulator I got this error (see image) in line:

        manager.Initialize("manager", key)

 

[Erel]

You should test this feature on a real device.

 

[Alberto Michelis]

Ok, any idea of since what version of android does it work?

 

[Alberto Michelis]

and... if I need to test with an emulator, is it enought just to comment this line ?

 

[Erel]

It should be supported on all versions.

and... if I need to test with an emulator, is it enought just to comment this line ?

You can catch this error with a Try / Catch block.

Adding Billing to a new app it cant locate any SKU and I can find why!

My code is identical to my old app wich works ok, except the key...

    Private key As String = "MIIBIjANBgkqhkiG9w0BA......"
    Dim Productid1, Productid2 As String
    Dim Producttype As String
    Dim DeveloperPayload As String
    DeveloperPayload="pac" 
    Producttype="inapp" 
    Productid1 = "profesional"

And this is what I get when I run it:

Billing service connected.
Checking for in-app billing 3 support.
In-app billing version 3 supported for armi.pac
Subscriptions AVAILABLE.
true, Setup successful. (response: 0:OK)
Info: Subscriptions supported: true
Starting async operation: refresh inventory
Querying owned items, item type: inapp
Package name: armi.pac
Calling getPurchases with continuation token: null
Owned items response: 0
Continuation token: null
Querying SKU details.
queryPrices: nothing to do because there are no SKUs.
Querying owned items, item type: subs
Package name: armi.pac
Calling getPurchases with continuation token: null
Owned items response: 0
Continuation token: null
Querying SKU details.
queryPrices: nothing to do because there are no SKUs.
Ending async operation: refresh inventory

But the app does has a SKU as you can see in the image.

What can be wrong?
Thanks

Have you already published the app? In some cases IAP only works after you publish the app. You can temporary publish it and then remove it.
