 #### Import jniLibs
 
 Due to file size limitations, jniLibs are too big to be published on npm. Use the assets on [GitHub Releases](https://github.com/ccnnde/react-native-simple-openvpn/releases/tag/v2.0.0) instead

 #### 导入 jniLibs
 
 由于存在文件大小的限制，jniLibs 无法随模块一起发布到 npm 上。故使用 [GitHub Releases](https://github.com/ccnnde/react-native-simple-openvpn/releases/tag/v2.0.0) 中的 assets 来代替
