React-Native Android 发布不久，尝试了一下，发现坑不少，姑且记录一下向导：
1.安装nodejs
2.安装git
3.clone react-native的项目:
git clone -b master https://github.com/facebook/react-native.git
如果被q就直接下master吧。
4.切换到react-native-cli目录中，安装react-native-cli
npm install -g
5.初始化AwesomeProject，貌似一个事例项目:
react-native init AwesomeProject
这里会下载项目和一些插件，需要耐心等待。
6.切换到react-native-cli\AwesomeProject\node_modules\react-native\packager\ 目录下，执行:
node packager.js
//或者在 react-native-cli\AwesomeProject 目录下执行 react-native start
发现报错，这个gist可以帮你解决这些问题，如果你无法打开，下面是原文转载:

Few Line of Hack Code Make React-Native Run on Windows
While React-Native just add support of Android,yet officeally they just only support on OSX.
After a few hours of debugging, I find a simple way of let React-Native run on Windows.
Make sure all requirements were all setup following this:
Then initilize the project following this:
The react-native run-android should deploy the app into you phone or AVD
While using 'react-native start' to run the dev server you may get some error couse it runs a bash file, goto /node_modules/react-native/local-cli/run-package.js,and change it to
'use strict';
var path = require('path');
var child_process = require('child_process');
module.exports = function(newWindow) {
if (newWindow) {
child_process.spawnSync('open', [
path.resolve(__dirname, '..', 'packager', 'launchPackager.command')
]);
} else {
child_process.spawn('node', [
path.resolve(__dirname, '..', 'packager', 'packager.js'),
'--projectRoots',
process.cwd(),
], {stdio: 'inherit'});
}
};
Skip the bash and run the nodejs script instead.
Then the problem shows, fix it, already make a pull request https://github.com/facebook/react-native/issues/2787
Finally get A blank Activity,try adb logcat fetch the error log find out that, while the app load js from
ip:8081/index.android.bundle?platform=android Then get moudle load error.
Because some the moudle path be resolve as "path\path\package",and while the were define where "path\path\package".
Goto project\node_modules\react-native\packager\react-packager\src\DependencyResolver\index.js
function defineModuleCode({moduleName, code, deps}) {
deps = deps.replace(/\\\\/g,'\\');
return [
`__d(`,
`'${moduleName}',`,
`${deps},`,
'function(global, require, module, exports) {',
` ${code}`,
'\n});',
].join('');
}
Since the moudle system were a litte bit complicate, this may not be the best solution, and neet more test before a pull request,but I think it will get you play around.
============
两个问题修改之后这时再次执行
node packager.js
就应该正常了。

浏览
http://localhost:8081/index.android.bundle?platform=android
如果可以访问表示服务器端已经可以了，浏览器中访问时，刚才的命令行会显示进度。
打开http://localhost:8081/debugger-ui，可以下载浏览器调试插件。
7.下载[url=http://developer.android.com/sdk/index.html]android studio[/url] ,自带模拟器。
安装之。
8.打开Android Studio=>File=>New=>Import Project...
react-native-cli\AwesomeProject\android
9.调试，编译（注意手机要开启调试模式），这时会打开选择编译的程序是真机还是模拟器，如果已经插入真机，但是无法看到，应该是需要安装机器的驱动。
10.选择真机，apk文件会被安装到手机。
11.使用react-native编译.
在react-native-cli\AwesomeProject目录下，Git Bash执行
react-native run-android
确保6步骤中的js server未关闭，
JS Server already running.
Building and installing the app on the device(cd android && gradlew.bat install Debug)...
......
......
BUILD SUCCESSFUL
......
直到可以看到apk被安装到手机。
打开apk，红屏，错误界面。fuck....
这个gist可以说明我目前遇到的情况，
这个问题已经被提到react-native的issue等待修正。
update 2015-10-10:
关于红屏错误界面的解决方法：
=======
To bundle JS file into your apk while having your server running (react-native start) download bundle into assets directory of your app:
curl "http://localhost:8081/index.android.bundle?platform=android" -o "android/app/src/main/assets/index.android.bundle"
With the next release (0.12) we'll fix react-native bundle command to work with android projects as expected.
=======
如果没有assets，需要新建一个。
附上几个截图：
