      onProductPurchasedMethod,
      onBillingErrorMethod,
      onPurchaseHistoryRestoredMethod=None,
      onBillingInitializedMethod=None,

  # onPurchaseHistoryRestoredMethod does not expect any arguments
  
  # onBillingInitializedMethod does not expect any arguments

Useful Methods

• Purchase a product

  purchase_product(product_id)

• Consume a product(non-subscription)

  consume_purchase_async(product_id, success_listener=None, error_listener=None)
  
  # Both success_listener and error_listener doesn't take any arguments

• Get details about a product (non-subscription)

  get_purchase_listing_async(product_id, success_listener=None, error_listener=None)
  
  # Both success_listener and error_listener expects a single argument.
  
  # success_listener gets a list with one element. Following details are available:
  if product_info.size() != 0:
      product_info = product_info[0]
      details= {
          "productId":        product_info.productId,
          "title":            product_info.title,
          "description":      product_info.description,
          "isSubscription":   product_info.isSubscription,
          "currency":         product_info.currency,
          "priceValue":       product_info.priceValue,
          "priceText":        product_info.priceText,
      }
  
  # error_listener gets a string with error message.

• Subscribe to a product

  subscribe_product(product_id)

• Get details about a subscription

  get_subscription_listing_async(product_id, success_listener=None, error_listener=None)
  
  # Both success_listener and error_listener expects a single argument.
  
  # Same as get_purchase_listing_async

• Update information about users owned purchases/subscriptions. Use it to restore Purchases & Subscriptions.

  load_owned_purchases_async(success_listener=None, error_listener=None)
  
  # Both success_listener and error_listener doesn't take any arguments.

• Check if service is initialized

  is_initialized()

• Check if a product is already purchased(non-subscription)

  is_purchased(product_id)

• Check if a product is already subscribed

  is_subscribed(product_id)

• Before any usage it's good practice to check in-app billing services availability. In some older devices or chinese ones it may happen that Play Market is unavailable or is deprecated and doesn't support in-app billing.

  is_iab_service_available()

• Please notice that calling BillingProcessor.isIabServiceAvailable() (only checks Play Market app installed or not) is not enough because there might be a case when it returns true but still payment won't succeed. Therefore, it's better to call bp.isConnected() after initializing BillingProcessor

  is_connected()

• List owned products(non-subscription)

  list_owned_products()
  
  # Returns a list of product ids

• List owned subscriptions

  list_owned_subscriptions()
  
  # Returns a list of product ids

• Get very detailed info about a product(non-subscription)

  get_purchase_info(product_id)
  
  # Returns a `PurchaseInfo` object. Following details are available:
  purchase_info = bp.get_purchase_info(product_id)
  details = {
      "responseData": purchase_info.responseData,
      "signature": purchase_info.signature,
      "purchaseData":{
          "orderId": purchase_info.purchaseData.orderId,
          "productId": purchase_info.purchaseData.productId,
          "purchaseTime": purchase_info.purchaseData.purchaseTime,
          "purchaseToken": purchase_info.purchaseData.purchaseToken,
          "purchaseState": purchase_info.purchaseData.purchaseState,
          "autoRenewing": purchase_info.purchaseData.autoRenewing,
      }
  }

• Get very detailed info about a subscription

  get_subscription_purchase_info(product_id)
  
  # Returns a `PurchaseInfo` object. Same as get_purchase_info
