BillingClient

public abstract class BillingClient

Main interface for communication between the library and user application code.

It provides convenience methods for in-app billing. You can create one instance of this class for your application and use it to process in-app billing operations. It provides synchronous (blocking) and asynchronous (non-blocking) methods for many common in-app billing operations.

It's strongly recommended that you instantiate only one BillingClient instance at one time to avoid multiple PurchasesUpdatedListener#onPurchasesUpdated callbacks for a single event.

All methods annotated with AnyThread can be called from any thread and all the asynchronous callbacks will be returned on the same thread. Methods annotated with UiThread should be called from the Ui thread and all the asynchronous callbacks will be returned on the Ui thread as well.

After instantiating, you must perform setup in order to start using the object. To perform setup, call the startConnection method and provide a listener; that listener will be notified when setup is complete, after which (and not before) you may start calling other methods. After setup is complete, you will typically want to request an inventory of owned items and subscriptions. See queryPurchasesAsync and queryProductDetailsAsync.

When you are done with this object, don't forget to call endConnection to ensure proper cleanup. This object holds a binding to the in-app billing service and the manager to handle broadcast events, which will leak unless you dispose it correctly. If you created the object inside the Activity#onCreate method, then the recommended place to dispose is the Activity#onDestroy method. After cleanup, it cannot be reused again for connection.

To get library logs inside Android logcat, set corresponding logging level. E.g.: adb shell setprop log.tag.BillingClient VERBOSE

Public methods

acknowledgePurchase

public abstract void acknowledgePurchase(
    AcknowledgePurchaseParams params,
    AcknowledgePurchaseResponseListener listener
)

Acknowledges in-app purchases.

Developers are required to acknowledge that they have granted entitlement for all in-app purchases for their application.

Warning! All purchases require acknowledgement. Failure to acknowledge a purchase will result in that purchase being refunded. For one-time products ensure you are using consumeAsync which acts as an implicit acknowledgement or you can explicitly acknowledge the purchase via this method. For subscriptions use acknowledgePurchase. Please refer to the integration guide for more details.

Parameters
`AcknowledgePurchaseParams params`	Params specific to this acknowledge purchase request.
`AcknowledgePurchaseResponseListener listener`	The listener for the result of the acknowledge operation returned asynchronously through the callback with the `BillingResponseCode`.

consumeAsync

public abstract void consumeAsync(
    ConsumeParams consumeParams,
    ConsumeResponseListener listener
)

Consumes a given in-app product. Consuming can only be done on an item that's owned, and as a result of consumption, the user will no longer own it.

Consumption is done asynchronously and the listener receives the callback specified upon completion.

Warning! All purchases require acknowledgement. Failure to acknowledge a purchase will result in that purchase being refunded. For one-time products ensure you are using this method which acts as an implicit acknowledgement or you can explicitly acknowledge the purchase via acknowledgePurchase. For subscriptions use acknowledgePurchase. Please refer to https://developer.android.com/google/play/billing/billing_library_overview#acknowledge for more details.
