 * Used to provide all the necessary purchase data to the {@link Qonversion.updatePurchase} method.

 * Requires Qonversion product identifiers - {@link productId} for the purchasing one and
 * {@link oldProductId} for the purchased one.
 *
 * If {@link offerId} is not specified for Android, then the default offer will be applied.
 * To know how we choose the default offer, see {@link ProductStoreDetails.defaultSubscriptionOfferDetails}.
 *
 * If you want to remove any intro/trial offer from the purchase on Android (use only a bare base plan),
 * call the {@link removeOffer} method.
