DESCRIPTION
Developers are used to using a single distribution channel for their Android applications. Yet submitting apps to only one store, even if it's the market leader, significantly limits the app’s potential user audience. On the other hand, uploading an app to multiple stores can be time-consuming and complicated, especially when it comes to having to integrate in-app purchase into your app for each new store. In my session I will tell you about useful open-source tools, which will make your cross-store app publishing a breeze, and show you some coding technique for a fast and easy in-app purchase API integration. As presented in DroidCon Tel Aviv 2014 by: Anastasia Karimova, Yandex http://il.droidcon.com

1. Samsung In App Purchase v2.0 IAP (In-App Purchase) v2.0 lets you use Samsung’s payment services inside apps. While v1.0 linked to the library jar file, v2.0 uses the AIDL (Android Interface Definition Language) to help the IAP process and applications communicate with each other. The latter makes it easier to link than the former.
1.1 Product Purchase The below figure shows the process where an application uses IAP to request the purchase of a product.
① Proceed with the Samsung account authorization process. ② Bind IAPConnector to enable the IAP API. ③ Call the init() method start resetting IAP and receive the results as a bundle.
