-# IRext Java Web API
-
-Indexing to the specified remote index and download IR binary file for it.
-
-## Android SDK Usage
-
-### 1. Register your APP
-Register your APP on irext SDK console [irext SDK console](http://site.irext.net/sdk), (You need to register an irext account first)
-
-You need to fetch the package name and SHA1 signature of your APP and fill these information as SDK registration information
-
-While your APP is registered, you can see the APP key and APP secret in your APP list
-
-### 2. Import the SDK
-You can either import this project or download the web-api .aar file from [Android SDK](https://irext-lib-release.oss-cn-hangzhou.aliyuncs.com/1.5.0/index-sdk/index-sdk-android-1.5.0.aar) and import to your Android APP project
-
-Add 2 meta-data tags to your AndroidManifest.xml providing APP key and secret get from step 1.
-```xml
-<meta-data
-    android:name="irext_app_key"
-    android:value="your app key" />
-
-<meta-data
-    android:name="irext_app_secret"
-    android:value="your app secret" />
-```
-
-### 3. Use the SDK
-
-Import classes:
-```java
-import net.irext.webapi.model.*;    
-import net.irext.webapi.WebAPIs;
-import net.irext.webapi.WebAPICallbacks.*;
-```
-Get web API instance:
-```java
-WebAPIs webApis = WebAPIs.getInstance();
-```
-Sign in for access id and token:
-```java
-SignInCallback signInCallback = new SignInCallback() {
-    @Override
-    public void onSignInSuccess(UserApp userApp) {
-        int id = userApp.getId();
-        int token = userApp.getToken();

-```java
-ListIndexesCallback listIndexesCallback = new ListIndexesCallback() {
-
-    @Override
-    public void onListIndexesSuccess(List<RemoteIndex> indexes) {
-    }
-
-    @Override
-    public void onListIndexesFailed() {
-    }
-
-    @Override
-    public void onListIndexesError() {
-    }
-};
-webApis.listRemoteIndexes(category.getId(), brand.getId(), city.getCode(), operator.getOperator_id(), listIndexesCallback);
-```
-Download IR binary for certain remote index:
-```java
-DownloadBinCallback downloadBinCallback = new DownloadBinCallback() {
-
-    @Override
-    public void onDownloadBinSuccess(InputStream inputStream) {
-    }
-
-    @Override
