+
+### Usage
+
+#### Geoip and Geosite
+v2rayNG release already embedded domain file `geoip.dat` and `geosite.dat`. However it is (probably) not the latest and not the most complete list.
+For power user, the embedded files can be easily replaced with the following steps:
+1. Launch v2rayNG (v1.4.9+)
+2. Find existing geoip.dat and geosite.dat in `Android/data/com.v2ray.ang/files/assets` (path may differ on some Android device)
+3. Replace them with the latest [domain list](https://github.com/v2fly/domain-list-community) and [ip list](https://github.com/v2fly/geoip)
+4. Enhanced version can be found in this [repo](https://github.com/Loyalsoldier/v2ray-rules-dat) (recommend to use `geosite:geolocation-!cn` for proxy dns and routing)
+5. It is also 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)
+
+#### See more in our [wiki](https://github.com/2dust/v2rayNG/wiki)
+
+### 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 But the v2ray core inside the aar is (probably) outdated.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 under AndroidLibV2rayLite folder. 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/)
+
+v2rayNG can run on Android Emulators, with minimum Android 5.0

-/**
- * 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.

However, this cache is not in sync with the main process list. In fact, we don't need to generate full config right before the service start. We only need to when active node is changed. This way, code logic and daemon process is kept simple	2020-12-04 22:37:31 -05:00
