Kay. So now that we've completed our …purchasing observer class let's start initiating some purchases from within our …application. So we're going to start in Game.java, and …that's the main activity where you're actually playing the game. …Now, the first thing you're going to need to do in any activity where you want to …provide In-APp purchases is in the onStart override method here. …What we need to do is create an instance of that In-App observer class.…
I'll just call it obs for short, is equal to new InAppObserver. …And remember, it's expecting the calling activity in which we can just say is …this. So now that we have that instance, now, …we need to register it as an observer with the purchasing manager. …It's going to be a static method of the PurchasingManager class and its going to …be registerObserver. And we're going to pass in that obs …property that we just created. So now, once we do this, it's now …going to go out register that observer, and when that's finished, the …onSDKAvailable call back method will actually be called in our observer class.…
The course also covers multiscreen development and testing with the Kindle Emulator, as well as actual deployment to the Kindle store.
