Download Sample App

You can download the IAP sample app at Github.

Add IAP Library

ONE store IAP library V6(SDK V19) and above does not support AIDL.

Refer to the followings on how to add ONE store IAP SDK.

Install ONE store app

ONE store Service (OSS) app is necessary for the developer or the user to use ONE store IAP.

OSS has been installed by default on Android smartphones released by local mobile carriers (SKT, KT, U+), but it has been installed by default neither on terminals (Pixel, etc.) nor on tablets released overseas.

Depending on the conditions of the terminals developing ONE store IAP modules, you need to download OSS and keep it up to date by using the guides below.

  • Smartphones released by local mobile carriers ONE store apps have been installed by default on Android smartphones launched by mobile carriers. The developer can update ONE store apps to the latest version by using ONE store client (OSC) app, a built-in app. Execute ONE store (or T Store or Olleh Market or U+Store) installed on the smartphone to update OSC and OSS (older devices may not be supported with automatic updates).

  • Smartphones/tablets released overseas & terminals distributed by manufacturers

    Since ONE store apps are not installed by default on the smartphones or tablets released oversea and on the terminals distributed by manufacturers, you must download and install OSC and OSS. Click on the link below and install ONE store apps necessary for IAP development (only available on mobile)

    Go to download OSC & OSS

    ONE store IAP API V6 (SDK V19) works on Android devices with Android OS 4.1 and above. Check the OS version of the terminals prior to interworking with the IAP module.
