+### 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 But the v2ray core inside the aar is (probably) outdated.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.
