可以参考官方github网站：facebook Movies appThe Movies app is a demonstration of basic concepts,such as fetching data,rendering a list of data including images,and navigating between different screens.

运行的命令如下：

git clone https://github.com/facebook/react-native.git
cd react-native
npm install

cd react-native ./gradlew :Examples:Movies:android:app:installDebug ./packager/packager.sh

./gradlew :Examples:Movies:android:app:installDebug 这个命令会执行比较久，下载一堆的东西。特别是执行到ReactAndroid:downloadBoost时会需要较长的时间。这一步其实是在下载一个文件，文件路劲如下,可以手动查看下载的进度，这个文件一百多兆。

这个例子编译运行了，运行另一个示例UIExplorer示例就很容易了，不过运行UIExplorer时你可能会碰到下面的错误，处理这个错误很easy，reload JS就可以了。

运行Movies和UIExplorer

react native都是用JS的语法写的，对于我们这些以前使用C++，java，object-c写客户端程序的gg来说，看起来很蛋痛，下一步准备学习下js语法咯
