Samsung In-App Purchasing

About

Samsung In-App Purchase (IAP) is a payment service that makes it possible to sell a variety of items in applications for Samsung Galaxy Store and internally manages communication with supporting IAP services in the Samsung ecosystem, such as Samsung Account, Samsung Checkout, and Samsung Rewards.

This section describes how to setup your AIR application to use Samsung In-App Purchase (IAP) with this extension.

Install

The simplest way to install and manage your AIR native extensions and libraries is to use the AIR Package Manager (apm). We highly recommend using apm, as it will handle downloading all required dependencies and manage your application descriptor (Android manifest additions, iOS info additions etc).

However you can choose to install it manually, as you would have done in the past.

info

Note: All of the commands below should be run in a terminal / command prompt in the root directory of your application, generally the level above your source directory.

If you don't have an APM project setup, expand the guide below to setup an APM project before installing the extension.

Setup APM

Install APM

If you haven't installed apm follow the install guide on airsdk.dev.

Setup an APM project

You will need an APM project for your application.

There are many ways to do this and for more options see the APM documentation. Here we will just initialise a new empty project:

apm init

Check your github token

We use github to secure our extensions so you must have created a github personal access token and configured apm to use it.

To do this create a token using this guide from github and then set it in your apm config using:

apm config set github_token ghp_XXXXXXXXXXXXXXXXXXXXXXXXXXXX

If you don't do this correctly you may find the install will fail.

Install the extension

Install the package by running:

apm install com.distriqt.InAppBilling-Samsung

This will download and install the extension, required assets, and all dependencies.

Once complete apm will have created something like the following file structure:

.
|____ ane
| |____ com.distriqt.InAppBilling.ane # InAppBilling extension
| |____ [dependencies]
|____ apm_packages # cache directory - ignore
|____ project.apm # apm project file
  • Add the ane directory to your IDE. See the tutorials located here on adding an extension to your IDE.
info

We suggest you use the locations directly in your builds rather than copying the files elsewhere. The reason for this is if you ever go to update the extensions using apm that these updates will be pulled into your build automatically.

caution

Only install one variant of an package. The base variant is installed when no variant is specified and cannot be included alongside another variant. You will likely get an error if you attempt to install multiple variants with apm

Application Descriptor

Updating your application descriptor will insert the required extensionID's and generate the manifest and info additions for your application.

You update your application descriptor by running:

apm generate app-descriptor src/MyApp-app.xml

Change the path (src/MyApp-app.xml) to point to your application descriptor.

caution

This will modify your application descriptor replacing the manifest additions and info additions with the ones generated from apm.

You should backup your application descriptor before running this command to ensure you don't lose any information.

If you need to insert custom data into these sections see the guides for Android and iOS

Checking for Support

You can use the isSupported flag to determine if this extension is supported on the current platform and device.

This allows you to react to whether the functionality is available on the device and provide an alternative solution if not.

if (InAppBilling.isSupported)
{
// Functionality here
}
note

This only checks if there is some functionality supported, not whether a particular billing service is available.
