 See our [guide in our website](http://weex.apache.org/guide/integrate-to-your-app.html) to learn more about how to integrate Weex SDK into your app.
 
-## Build Environment
-The environment required to build weex is:
-* Android SDK:
-    * NodeJS 4.0+
-    * JDK 1.6+
-    * Android SDK(`$ANDROID_HOME` must be set properly)
-    * Gradle 2.0+
-    * NDK r18 and ndk 13 (**Both of them are needed**)
-    * [Ninja 1.8.2+](https://ninja-build.org/)
-    * CMake 3.9.0+
-* iOS SDK:
-    * NodeJS 4.0+
-    * XCode & Command Tools 8.0+
-* Mobile web SDK:
-    * NodeJS 4.0+
+# Build Environment
+The environment required to build weex is categorized by platforms.
+
+## Android
+* JDK `1.8+`
+* Android SDK Platform 28
+  * `ANDROID_HOME` must be configured by using `export ANDROID_HOME=/path_to_sdk`
+  * Normally, you should install [Android Studio](https://developer.android.com/studio) to get Android SDK Platform 28 installed.
+* Gradle 4.10+
+* NDK `r18`
+  * `ANDROID_NDK_HOME` must be configured by using `export ANDROID_NDK_HOME=/path_to_ndk`
+  * Higher version of NDK than `r18` isn't not tested yet.
+* CMake 3.4.1+
+
+## iOS
+* Install [iOS Environment](https://developer.apple.com/library/ios/documentation/IDEs/Conceptual/AppStoreDistributionTutorial/Setup/Setup.html)
+* Install [CocoaPods](https://guides.cocoapods.org/using/getting-started.html)
+* XCode Command Tools 8.0+
+
+## Mobile
+* NodeJS 4.0+
 
 This article was tested in MacOSX system.
 
 # Build All by Script
 
 This script will build Android and iOS SDKs:
-> `$ bash scripts/build_from_source.sh $NDK13_dir $NDK_16dir`
+> `$ bash scripts/build_from_source.sh `
 
-The `$NDK18_dir` should be the directory of NDK 18, otherwise the Android build would failed.
-
-This may take a while. After that, you can look in `dist/`, `android/sdk/build/output/` and `ios/sdk/Products` for Web/Android/iOS SDK artifacts.

 ### Before build Native SDK
 Move `min` version to Native SDK folder, which will be used by native SDK build.

 ## Build Android SDK
+1. Install the [Android environment](#android).
+2. Execute the following command
 
-check env
+    ```
+    cd android
+    ./gradlew :weex_sdk:clean :weex_sdk:assembleRelease

-You can now import the aar file to your android project.
+3. Output can be found at `android/sdk/build/outputs/aar`
 
 ## Build iOS SDK
 Execute command below to compile iOS SDK:
-> `$ xcodebuild -project ios_sdk/WeexSDK.xcodeproj -target WeexSDK_MTL`
+> `$ xcodebuild -project ios/sdk/WeexSDK.xcodeproj -target WeexSDK_MTL`

+New users of Weex should always choose `weex_sdk`, while for existing users, using `weex_sdk` could cause compiling issues and you could use `weex_sdk_legacy` for temporary solution. See below for detail.
+
+#### weex_sdk_legacy
+`weex_sdk_legacy`  is provided only for backward compatibility reason, and **would not be maintained in the future**. Please migrate to `weex_sdk` when you are available.
+
+`weex_sdk_legacy` is built by `./gradlew clean assembleRelease -PapachePackageName="false"`, where all java files in `.aar` is under `com.taobao.weex`
+
+## Android-Studio integrated

Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.All Apache Weex releases are in the form of source code, binary/bytecode packages are produced as a convenience to users.
