Characteristics of ONE store In-App Purchase V5

  • Improvements made in IAP V5 (SDK V17) are as follows.

    ItemImprovement DetailsDescription


    Introduce 'Consume' concept

    If an item is failed to be provided, a logic is provided for recovery of the item in the app.

    Provide support for Custom PID

    Developers can directly enter an In-App ID (PID), and therefore create and manage an intuitive PID.

    Provide a universal IAP interface

    Apps which have been developed for other markets can be launched on ONE store without significant development efforts made in coding.

    Billing Test Environment

    Provide separate development/commercial test environments

    ONE store's test environment is provided which is almost equal to a developer's verification environment.In the development environment of developers, development/tests can be performed by being interworked with ONE store's Sandbox. The commercial environment of developers enables billing to be made in ONE store's commercial environment. In case when the billing is made by logging in to ONE store with an ID which is registered as ONE store ID on ONE store's Developer Center, developers are allowed to freely cancel the purchase.

    Payment Window UI

    Available to select a full payment screen, a payment pop-up screen.

    In addition to the existing full payment screen, a pop-up payment screen is newly provided. Among these two types of the payment screen, you set the screen in the app depending on the UI style you prefer.(refer to '4. Preparatory Work' > 'Set Android Manifest File')

    Interworking Method

    IAvailable to select IAP SDK, and AIDL

    Not only through the existing SDK method, you can directly interwork with the OSS by using AIDL.

    However, IAP does not work in terminals without the OSS installed (refer to '4. Preparatory Work' > ' Install ONE store App )

    Developer Center

    Improve a feature for crawling other market's app product information.

    Apps which were already registered on other markets can be easily registered on ONE store.

    Provide a feature to 'import' in-app product information from other markets.

    Authentication Center

    Issue/Authenticate/Manage OAuth

    Data security is enhanced at the time when a developer's server and ONE store's IAP server are interworked with each other.

Migration to API V5

  • Once you have adopted an API V4(below SDK V16.04.00) in your app, you are not allowed to upgrade it to the API V5(SDK V17).

  • You can maintain your app without applying the newest SDK, and ONE store will continuously support the billing services for the API V4.
