How to Use the Sample

  2. Open the project file:
    • Object Pascal: CapitalTrivia.dproj
    • C++: CapitalTriviaCpp.cbproj
  3. Follow the steps below.

Define the Required Products

On the constants definition section of the Main unit, the application defines the ID of two products. You must define in your store (Google Play, iTunes or both) two new products with the same properties as these two non-consumable products:

Object Pascal:

const
  EuropeID = 'com.embarcadero.capitals.europe';
  NoAdsID = 'com.embarcadero.capitals.noads';

C++:

const String EuropeID = "com.embarcadero.capitals.europe";
const String NoAdsID = "com.embarcadero.capitals.noads";

To define these products in your store, follow the instructions bellow for your in-app payment service or services:

Google Play In-app Billing iOS In-App Purchase
Prerequisites Prerequisites

After you define these products in your store, update Main.pas with the actual IDs that you specified in your store for these four products.

Configure Your Google Keys

For the Google Play In-app Billing service, you must follow the instructions at Establishing a Connection to Your In-App Payment Service. You must provide your application license key in the ApplicationLicenseKey property, which the sample sets on the FormCreate event handler. See Configuring the Connection Data for Your In-App Payment Service.

For the AdMob service, you must follow the instructions at Configuring the Connection Data for Your Advertising Service. You must provide your ad unit ID in the AdUnitID property, which the sample sets on the InAppPurchaseSetupComplete event handler.
