Android Question Billing Manager 3 "Weak reference error"

[Javier Alonso]

Hi,

I'm getting the error:

Billing service connected.
Checking for in-app billing 3 support.
In-app billing version 3 supported for xxxxxxxxxxxxxxxx
Subscriptions AVAILABLE.
Subscriptions supported: true
** Activity (principal) Resume **
Error occurred on line: 89 (DownloadService)
java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.Object java.lang.ref.WeakReference.get()' on a null object reference

when running in-app billing from a service using the code:

Sub Service_Start (StartingIntent As Intent)
    manager.Initialize("manager", key)
    manager.DebugLogging = True
End Sub

Sub Buy (producto As String, payload As String)
    manager.RequestPayment(producto, "inapp", payload)
End Sub

Sub Manager_BillingSupported (Supported As Boolean, Message As String)
    Log("Subscriptions supported: " & manager.SubscriptionsSupported)
End Sub

The line cousing the error is the call to requestpayment. What is wrong? It used to work when I embedded it in the main activity.

1. You can only call RequestPayment from an Activity.
2. You shouldn't initialize objects in Service_Start. Only Service_Create.

Note that you can make it a public variable and use it from an Activity. The PurchaseCompleted event will be raised in the activity.

Thank you, I got it working.
