 # IRext Java Web API
 
 Indexing to the specified remote index and download IR binary file for it.
-    
-Please refer to the README in subfolders for [Android](https://github.com/irext/irext-web-api/tree/master/android-sdk) and [Java web](https://github.com/irext/irext-web-api/tree/master/web-sdk).
+
+## Android SDK Usage
+
+### 1. Register your APP
+Register your APP on irext SDK console [irext SDK console](http://irext.net), (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](http://irext-lib-releaese.oss-cn-hangzhou.aliyuncs.com/decode/0.1.2/web-api-android-0.1.2.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();
+    }
+
+    @Override
+    public void onSignInFailed() {
+    }
+
+    @Override
+    public void onSignInError() {
+    }
+};
+webApis.signIn(context, signInCallback);
+```

+    }
+
+    @Override
+    public void onListCategoriesError() {
+    }
+};
+webApis.listCategories(listCategoriesCallback);
+```
+Fetch brands of a certain category other than STB:
+```java
+ListBrandsCallback listBrandsCallback = new ListBrandsCallback() {

+```
+Fetch STB operators of a certain city:
+```java

+
+    @Override
+    public void onListOperatorsSuccess(List<StbOperator> operators) {
+    }
+
+    @Override
+    public void onListOperatorsFailed() {
+    }
+
+    @Override
+    public void onListOperatorsError() {
+    }
+};
+webApis.listOperators(cityCode, listOperatorCallback);
+```
+Fetch remote indexes of a certain brand or STB operator:
+```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
+    public void onDownloadBinFailed() {
+    }
+
+    @Override
+    public void onDownloadBinError() {
+    }
+};
+webApis.downloadBin(remoteIndex.getRemote_map(), remoteIndex.getId(), downloadBinCallback);
+```
