# 如何快速测试
### 1. 安装最新版本的Android Studio
可以从https://developer.android.com/studio 下载。本Demo使用是4.0版本Android Studio编写。
### 2. 按照NDK 20 以上版本
Demo测试的时候使用的是NDK 20b版本,20版本以上均可以支持编译成功。
如果您是初学者,可以用以下方式安装和测试NDK编译环境。
点击 File -> New ->New Project, 新建 "Native C++" project
### 3. 导入项目
点击 File->New->Import Project..., 然后跟着Android Studio的引导导入
# 获得更多支持
前往[端计算模型生成平台EasyEdge](https://ai.baidu.com/easyedge/app/open_source_demo?referrerUrl=paddlelite),获得更多开发支持:
- Demo APP:可使用手机扫码安装,方便手机端快速体验文字识别
- SDK:模型被封装为适配不同芯片硬件和操作系统SDK,包括完善的接口,方便进行二次开发
