在上一节中，我们通过一个相册的制作来学习了React Native编写。这一节我们需要开始学习React Native的源码。
学习源码，从编译源码开始。
首先，我们需要把代码从github中克隆下来。
https://github.com/facebook/react-native.git
git checkout -b 0.23-stable remotes/origin/0.23-stable
我们首先升级一下我们的react-native，因为等下创建项目最好使用最新版本的。
首先，我们需要查询最新版本：
nam info react-native
npm install --save react-native@0.22.2
react-native init videolegend
完事之后，打开项目顶层的package.json文件：
{
"name": "videolegend",
"version": "0.0.1",
"private": true,
"scripts": {
"start": "node node_modules/react-native/local-cli/cli.js start"
},
"dependencies": {
"react": "^0.14.8",
"react-native": "^0.22.2"
}
}
接下来，我们来进行源码的编译。编译源码，官网有一个页面，我们的过程呢，也是基于它的，但如果你完全基于它，那么你是会吃亏的。
所以，为什么我要写一篇文章出来，给大家作为参考。
官网源码编译地址：点击打开链接
前置条件：
1、SDK ： compileSdkVersion 23
2、SDK build tools : 23.0.1
3、Android Support Repository >=17
4 、 NDK (4.8哦就是 ndk-r10b,，4.9都不行,会坑出很多问题，如果NDK版本不对。）
使用AndroidStudio打开项目。
1、项目顶层build.grade的配置：
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:1.3.1'
//加下面这一行
classpath 'de.undercouch:gradle-download-task:2.0.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
mavenLocal()
jcenter()
maven {
// All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
url "$projectDir/../../node_modules/react-native/android"
}
}
}
rootProject.name = 'videolegend'
include ':app'
include ':ReactAndroid'
project(':ReactAndroid').projectDir = new File('/Users/zengjinlong/workplace/react/reactnativesrc/react-native/ReactAndroid')
3、更改项目依赖：在应用模块的build.gradle里面更改依赖部分：
dependencies {
compile fileTree(dir: "libs", include: ["*.jar"])
compile "com.android.support:appcompat-v7:23.0.1"
//compile "com.facebook.react:react-native:+" // From node_modules
compile project(':ReactAndroid')
}官网到这里，就叫你可以run啦。呵呵，too young too simple。
首先，ReactAndroid里面的有些下载任务你给它再多时间都不可能完成。所以。。。我们需要离线下载好。然后更改其脚本，进行编译。
1、离线下载好
boost_1_57_0
double_conversion-1.1.1
folly-deprecate-dynamic-initializer
glog-0.3.3
jsc头文件
然后按照目录放到ReactAndroid的build/downloads/目录下面。大概有450M内容。
2、修改ReactAndroid的build.grade脚本
主要是删掉那些下载任务的脚本，直接进入拷贝任务和编译任务。
来，我们来感受一下修改前和修改后的区别。
首先，修改前：

然后可以编译了。注意ndk版本，在local.properties文件里面设定：
ndk.dir=/Users/zengjinlong/workplace/android-ndk-r10b sdk.dir=/Users/zengjinlong/workplace/android-sdk-macosx
然后，在项目的顶层，npm start 。
注意，我们并没有将ReactAndroid 装载到node_module里面。因为这样容易出问题，所以这也是跟官网差异的一个地方。就是，工程依赖是通过源码。但是npm start的，其实是node_module里面的，也就是0.22.2
好，今天就到这里。有什么不懂的，可以来问我。
