Samsung Galaxy apps

Extended functionality

Developer mode testing

Developer mode allows you to carry out IAP testing without incurring real-world monetary charges for products. To get started, create your configuration with an ISamsungAppsConfiguration instance, with its mode set to SamsungAppsMode.AlwaysSucceed:

var builder = ConfigurationBuilder.Instance(StandardPurchasingModule.Instance());

// Enable "developer mode" for purchases, not requiring real-world money

// SamsungAppsMode has: Production (developer mode "off"), AlwaysSucceed, AlwaysFail


Restoring transactions

Users restore transactions to maintain access to content they’ve already purchased (for example, when they upgrade to a new phone, they don’t lose all of the items they purchased on the old phone). The Samsung Galaxy App Store does not require previous transactions to be restored. However, you could improve in-app usability by providing users with a button allowing them to restore their purchases, for instance if they have installed the app on a different device.

During this process, the ProcessPurchase function of your IStoreListener is invoked for any items the user already owns. The following example illustrates such a call. This could be called from a Restore Purchases button:

/// <summary>

/// Your IStoreListener implementation of OnInitialized.

/// </summary>

public void OnInitialized(IStoreController controller, IExtensionProvider extensions)


    // The ProcessPurchase function is invoked for any items the user already owns

    extensions.GetExtension<ISamsungAppsExtensions>().RestoreTransactions(result => {

        if (result) {

            // This does not mean anything has been restored,

            // just that the restoration process succeeded.

        } else {

            // Restoration failed.




On Samsung Galaxy platforms, users may be required to input their Samsung Galaxy App Store password to retrieve previous transactions, if they haven’t already done so.
