Working with purchase data from android clients

purchase_data and data_signature are the values android app gets from a purchase request. See https://developer.android.com/google/play/billing/billing_reference.html#getBuyIntent

purchase = AndroidInAppBilling::InappPurchase.new(data: purchase_data, signature: data_signature)

# attribute accessors:
purchase.token # => JWT token
purchase.auto_renewing # => true/false
# ... (other attributes, see `AndroidInAppBilling::InappPurchase` and the link above)

# signature validation:
purchase.signature_valid? # => true/false

Working with purchase updates

To get current subscription state this gem uses android publisher v2 API

client = AndroidInAppBilling::PublisherClient.new
subscription = client.get_subscription_purchase(purchase.product_id, purchase.token)

# attribute accessors:
subscription.payment_state # => 'pending' / 'trial' / 'received'
subscription.expires_at # => some DateTime
# ... (other attributes, see `AndroidInAppBilling::SubscriptionPurchase` and the link above)
