+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including

+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable

+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.

+# DCS SDK（Java）开发者指南
+
+## DCS协议
+
+DCS协议是DuerOS服务端与设备端之间的通讯协议，是一套把DuerOS的智能语音交互能力向所有设备开放的API，了解详情请看[DCS协议文档](http://developer.dueros.baidu.com/doc/dueros-conversational-service/introduction_markdown)。
+
+## 摘要
+
+DCS SDK提供DCS协议在设备端的实现，旨在降低设备接入DuerOS的开发成本。DCS SDK是完整的Sample App，可以直接在目标设备运行，并且源代码全部开源，开发者可以基于源码进行二次开发。
+
+本文档介绍的DCS SDK（Java）是Java版本的实现，该版本目前支持Android系统。
+
+## 1-前置条件
+
+a.完成注册百度账号、开发者认证和产品创建（选择手机场景和Android平台）后，请保存client_id和client_secret
+
+![](images/client-id-secret.png)
+
+具体参考[控制台接入流程](http://developer.dueros.baidu.com/doc/overall/console-guide_markdown)。
+
+b.在百度开发者中心配置OAuth的授权回调页
+  1. 到DuerOS开放平台控制台： http://developer.dueros.baidu.com/openduer/product/getproduct
+  2. 点击所创建产品的“编辑”按钮，按钮在右侧
+  3. 点击OAUTH CONFIG URL，到百度开发者平台控制台
+  4. 在开发者平台控制台，点击左侧“安全设置”
+  5. 在“授权回调页”输入框中输入"bdconnect://cancel,bdconnect://success"（不带双引号）
+  6. 点击页面下方“确定”按钮
+
+c.开发环境
+  - Android Studio 2.2+
+  - Gradle 2.2+
+  - Android SDK 5.0+ (支持http/2)
+  - JDK 1.6+
+
+## 2-克隆项目
+
+```shell
+git clone https://github.com/dueros/dcs-sdk-java.git
+```
+
+## 3-运行
+
+a.通过Android Studio找到DcsSampleOAuthActivity.java，利用上述client_id进行替换
+
+![](images/modify-client-id.png)  
+
+b.运行（Android真机）
+
+![](images/login1.png)
+
+c.百度账号登录
+
+![](images/login2.png)
+
+## 4-唤醒
+
+说“小度小度”，成功唤醒后进入“录音中”状态，如下图：
+
+![](images/wakeup.png)
+
+## 5-和小度对话
+
+a.通过唤醒或者单击“点击说话”进入录音状态， 问“北京天气怎么样”，DuerOS后端将发送stopListen指令，同时返回speak指令，播报北京天气。
+
+b.问“播放刘若英的歌”, 返回play指令播放歌，可以从界面上进行“播放”、“暂停”、“上一首”和“下一首”操作。
+
+## 6 SDK结构
