Description

Platform service that provides support for in-app payment services. This platform service is only implemented on Android and iOS.

Instead of accessing this platform service directly, you can use a wrapper such as TInAppPurchase.

This platform service keeps a list of all instances of TCustomInAppPurchase and subclasses (such as TInAppPurchase). These instances are responsible for adding themselves to this list when they are created, and removing themselves from the list when they are destroyed. If you subclass TCustomInAppPurchase but you do not inherit its constructor and destructor, remember to do this as well: 

constructor MyComponent.Create(AOwner: TComponent);
var
  IAPIntf: IInterface;
begin
  if TPlatformServices.Current.SupportsPlatformService(
    IFMXInAppPurchaseService, IAPIntf) then
  begin
    FInAppPurchaseService := IFMXInAppPurchaseService(IAPIntf);
    FInAppPurchaseService.AddComponent(Self);
  end;
end;

destructor MyComponent.Destroy;
begin
  if Assigned(FInAppPurchaseService) then
    FInAppPurchaseService.RemoveComponent(Self);
  FInAppPurchaseService := nil;
end;
