 ### Usage
 
-#### Geoip and Geosite
-- geoip.dat and geosite.dat files are in `Android/data/com.v2ray.ang/files/assets` (path may differ on some Android device)
-- download feature will get enhanced version in this [repo](https://github.com/Loyalsoldier/v2ray-rules-dat) (Note it need a working proxy)
-- latest official [domain list](https://github.com/v2fly/domain-list-community) and [ip list](https://github.com/v2fly/geoip) can be imported manually
-- possible to use third party dat file in the same folder, like [h2y](https://guide.v2fly.org/routing/sitedata.html#%E5%A4%96%E7%BD%AE%E7%9A%84%E5%9F%9F%E5%90%8D%E6%96%87%E4%BB%B6)

 ### Development guide
 
 Android project under V2rayNG folder can be compiled directly in Android Studio, or using Gradle wrapper. But the v2ray core inside the aar is (probably) outdated.  
-The aar can be compiled from the Golang project [AndroidLibV2rayLite](https://github.com/2dust/AndroidLibV2rayLite) or [AndroidLibXrayLite](https://github.com/2dust/AndroidLibXrayLite).
-For a quick start, read guide for [Go Mobile](https://github.com/golang/go/wiki/Mobile) and [Makefiles for Go Developers](https://tutorialedge.net/golang/makefiles-for-go-developers/)

+ * InAppBillingService is the service that provides in-app billing version 3 and beyond.
+ * This service provides the following features:
+ * 1. Provides a new API to get details of in-app items published for the app including
+ *    price, type, title and description.
+ * 2. The purchase flow is synchronous and purchase information is available immediately
+ *    after it completes.
+ * 3. Purchase information of in-app purchases is maintained within the Google Play system
+ *    till the purchase is consumed.
+ * 4. An API to consume a purchase of an inapp item. All purchases of one-time
+ *    in-app items are consumable and thereafter can be purchased again.
+ * 5. An API to get current purchases of the user immediately. This will not contain any
+ *    consumed purchases.
+ *
+ * All calls will give a response code with the following possible values
+ * RESULT_OK = 0 - success
+ * RESULT_USER_CANCELED = 1 - user pressed back or canceled a dialog
+ * RESULT_BILLING_UNAVAILABLE = 3 - this billing API version is not supported for the type requested
+ * RESULT_ITEM_UNAVAILABLE = 4 - requested SKU is not available for purchase
+ * RESULT_DEVELOPER_ERROR = 5 - invalid arguments provided to the API
+ * RESULT_ERROR = 6 - Fatal error during the API action
+ * RESULT_ITEM_ALREADY_OWNED = 7 - Failure to purchase since item is already owned
+ * RESULT_ITEM_NOT_OWNED = 8 - Failure to consume since item is not owned

+/**
+ * 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, as well as automatic signature
+ * verification.
+ * <p>
+ * After instantiating, you must perform setup in order to start using the object.
+ * To perform setup, call the {@link #startSetup} method and provide a listener;
+ * that listener will be notified when setup is complete, after which (and not before)
+ * you may call other methods.
+ * <p>
+ * After setup is complete, you will typically want to request an inventory of owned
+ * items and subscriptions. See {@link #queryInventory}, {@link #queryInventoryAsync}
+ * and related methods.
+ * <p>
+ * When you are done with this object, don't forget to call {@link #dispose}
+ * to ensure proper cleanup. This object holds a binding to the in-app billing
+ * service, which will leak unless you dispose of it correctly. If you created
+ * the object on an Activity's onCreate method, then the recommended
+ * place to dispose of it is the Activity's onDestroy method.
+ * <p>
+ * A note about threading: When using this object from a background thread, you may
+ * call the blocking versions of methods; when using from a UI thread, call
+ * only the asynchronous versions and handle the results via callbacks.
+ * Also, notice that you can only call one asynchronous operation at a time;
+ * attempting to start a second asynchronous operation while the first one
+ * has not yet completed will result in an exception being thrown.
