Integrate IAP Helper into Your App

To prepare for integrating IAP features and testing the integration, perform the following.

Download IAP Helper and sample apps

Download the IAP SDK from this site.

The zipped file contains the SDK and sample projects that uses the IapHelper:

Location	Module	Description
./Libs	IAP6Helper	IAP SDK
./Samples	IAP6Sample	Sample Java app using IAP SDK
./Samples	IAP6SampleKotlin	Sample Kotlin app using IAP SDK

NoteIAP v6.0 is supported since Android API 18 or higher. It does not work properly in lower versions.

Create a project with a unique package name

Create a project in Android Studio with a package name that is different from the app registered in other app stores.

CautionIf package names are not different, app update malfunctions and problems with marketing and promotional support may occur.

Add the IAP Helper to your app

Click File → New → Import module.
Select the IAP6Helper folder from the Source Directory, and click Finish.
From Project Explorer, click Open Module Settings or press F4 → Dependencies tab.
Select your app module, and click + → Module Dependency from Declared Dependencies.
Select the IAP6Helper module, and click OK.

Add permissions to AndroidManifest.xml

Add these permissions to AndroidManifest.xml:

com.samsung.android.iap.permission.BILLING to connect to IAP and enable in-app item registration in Seller Portal.
android.permission.INTERNET because IAP uses the internet.

<uses-permission android:name="com.samsung.android.iap.permission.BILLING"/>
<uses-permission android:name="android.permission.INTERNET"/>

Register an app and in-app items in Seller Portal

During IAP integration, you may need to test IAP features.
Samsung IAP needs information about your app and in-app items registered in Seller Portal.

With the com.samsung.android.iap.permission.BILLING permission added to your app’s AndroidManifest.xml file, you can register an incomplete app and one or more in-app items.

NoteYour app does not need to have IAP features integrated in order to register the app and its in-app items.
As IAP integration proceeds, you can upload new versions of your app and new in-app items as needed.

Sign in to Seller Portal using your Samsung account.
Click Add New App
Click Android, select the default language, and click Next.
