編輯:關於Android編程
在上一節中,我們通過一個相冊的制作來學習了React Native編寫。這一節我們需要開始學習React Native的源碼。
學習源碼,從編譯源碼開始。
首先,我們需要把代碼從github中克隆下來。
https://github.com/facebook/react-native.git
git checkout -b 0.23-stable remotes/origin/0.23-stable
我們首先升級一下我們的react-native,因為等下創建項目最好使用最新版本的。
首先,我們需要查詢最新版本:
nam info react-native
npm install --save [email protected]
react-native init videolegend
完事之後,打開項目頂層的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" } }
接下來,我們來進行源碼的編譯。編譯源碼,官網有一個頁面,我們的過程呢,也是基於它的,但如果你完全基於它,那麼你是會吃虧的。
所以,為什麼我要寫一篇文章出來,給大家作為參考。

前置條件:
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,會坑出很多問題,如果NDK版本不對。)
使用AndroidStudio打開項目。
1、項目頂層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' //加下面這一行 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、更改項目依賴:在應用模塊的build.gradle裡面更改依賴部分:
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') }
官網到這裡,就叫你可以run啦。呵呵,too young too simple。
首先,ReactAndroid裡面的有些下載任務你給它再多時間都不可能完成。所以。。。我們需要離線下載好。然後更改其腳本,進行編譯。
1、離線下載好
boost_1_57_0
double_conversion-1.1.1
folly-deprecate-dynamic-initializer
glog-0.3.3
jsc頭文件
然後按照目錄放到ReactAndroid的build/downloads/目錄下面。大概有450M內容。
2、修改ReactAndroid的build.grade腳本
主要是刪掉那些下載任務的腳本,直接進入拷貝任務和編譯任務。
來,我們來感受一下修改前和修改後的區別。
首先,修改前:

然後可以編譯了。注意ndk版本,在local.properties文件裡面設定:
ndk.dir=/Users/zengjinlong/workplace/android-ndk-r10b sdk.dir=/Users/zengjinlong/workplace/android-sdk-macosx
然後,在項目的頂層,npm start 。
注意,我們並沒有將ReactAndroid 裝載到node_module裡面。因為這樣容易出問題,所以這也是跟官網差異的一個地方。就是,工程依賴是通過源碼。但是npm start的,其實是node_module裡面的,也就是0.22.2
好,今天就到這裡。有什麼不懂的,可以來問我。
