Join Albert Lo for an in-depth discussion in this video Set up for querying purchased Items, part of Android App Development: In-App Purchasing.
- [Instructor] Before we can query the IAB Gateway…for purchase items, we need to set up an interface.…The purpose of this interface is to enable…IAB Gateway to talk to our app without having…to know any details about our app.…So to create our interface, let me first clear out…some of these files…and then I'm going to open the project view,…and under the project view, we're going…to create a new package.…A new package will be under photos integration.…
And I select new package and I will call it IAB.…And then in this new package, let's create…a new Java class.…We will name the interface IAB Gateway Listener.…And the type will be interface.…So in this listener we're going to define…a couple of methods.…First one is onProgress.…We'll pass in an optional boolean parameter…to begin.…
Let's also define a method for handling errors…and then now we have some IAB methods.…The first one will be onSubscriptionAdded…and it'll take two parameters.…The first one, isSuccess.…The second one is a boolean parameter also…called isRestored.…
