React Native Android入门实战及深入源代码分析系列（2）——React Native源代码编译

本文为老曾原创。转载需注明出处：http://blog.csdn.net/minimicall?viewmode=contents

在上一节中，我们通过一个相冊的制作来学习了React Native编写。这一节我们须要開始学习React Native的源代码。

学习源代码，从编译源代码開始。

首先。我们须要把代码从github中克隆下来。

https://github.com/facebook/react-native.git

然后，我们能够切换到它的稳定分支，2016-03-30是我的操作时间，这个时候0.23-stable是最新的稳定版本号。

git checkout -b 0.23-stable remotes/origin/0.23-stable

我们首先升级一下我们的react-native。由于等下创建项目最好使用最新版本号的。

首先。我们须要查询最新版本号：

nam info react-native

得到最新版本号是0.22.2

npm install --save react-native@0.22.2

接下来，创建一个项目：

react-native init videolegend

好，等待漫长的初始化过程。

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"
}
}

能够看出我们的一个版本号的基本信息。

接下来，我们来进行源代码的编译。编译源代码。官网有一个页面，我们的过程呢，也是基于它的，但假设你全然基于它，那么你是会吃亏的。

所以，为什么我要写一篇文章出来，给大家作为參考。

官网源代码编译地址：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,会坑出非常多问题，假设NDK版本号不正确。）

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'
//加以下这一行
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"
}
}
}

2、加入ReactAndroid模块，在顶层的setting.grade文件里。配置例如以下：

rootProject.name = 'videolegend'

include ':app'
include ':ReactAndroid'
project(':ReactAndroid').projectDir = new File('/Users/zengjinlong/workplace/react/reactnativesrc/react-native/ReactAndroid')

那个绝对文件夹是我的，你仅仅须要改成你的即可。

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')
}

凝视掉原来的，更改为模块依赖。

官网到这里。就叫你能够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毕。所以。

。。

我们须要离线下载好。

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

然后依照文件夹放到ReactAndroid的build/downloads/文件夹以下。大概有450M内容。

2、改动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，我们来感受一下改动前和改动后的差别。

首先。改动前：

去掉了那些下载，由于我们已经下载好，扔进去。至于那些怎么下载，大家就自己自行想办法吧，反正一个个下载。

然后能够编译了。

注意ndk版本号。在local.properties文件中面设定：

ndk.dir=/Users/zengjinlong/workplace/android-ndk-r10b
sdk.dir=/Users/zengjinlong/workplace/android-sdk-macosx

OK，跑起来。

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。由于这样easy出问题，所以这也是跟官网差异的一个地方。就是，project依赖是通过源代码。可是npm start的，事实上是node_module里面的，也就是0.22.2

好，今天就到这里。有什么不懂的，能够来问我。
