Cordova构建Android，IOS工程实例_: щ

cordova是用web编写的移动端程序，通过调用原生SDK的方式在js内部编写交互程序，然后加壳包装。

重要提示

采用混合开发的方式可以有很多种，具体要根据项目的不同类型采用不同的方式，cordova是一款不错的混合框架，但是仍然无法和原生比性能，来自cordova官方的建议是如果你要做的是大型应用或者数据量较大，cordova并不是最佳选择。

环境配置

• Node 6.9.2
• Android
  
  • Git 2.11
  • AndroidSDK(v19及以上)
  • JDK(7及以上)
• IOS
  
  • Xcode
  • 终端
• 以下演示都用Android为例，不同的地方会标注

安装Cordova

这几天一直用GitShell，直到今天突然发现windows居然也可以用，所以就直接演示windows下的吧

• 打开git
• 安装npm install -g cordova
• 检查cordova -version or cordova -v

创建一个Cordova项目

• 创建一个workspace
  
  • C:\Users\Administrator>cd E:\Cordova
  • C:\Users\Administrator>e:
• 创建项目
  
  • E:\Cordova>cordova create CordovaWindows com.jty.mycordova MyCordova
  • 得到提示Creating a new cordova project.
  • down！
• 创建释义
  
  • CordovaWindows 项目名
  • com.jty.mycordova包名
  • MyCordovaAppName

添加平台支持

• 进入刚创建的工程目录
• windows
  
  • cordova platform add android
• Mac
  
  • $ cordova platform add IOS
  • $ cordova platform add android

• 运行结果如下

  E:\Cordova\CordovaWindows>cordova platform add android
  Adding android project...
  Creating Cordova project for the Android platform:
      Path: platforms\android
      Package: com.jty.mycordova
      Name: MyCordova
      Activity: MainActivity
      Android target: android-25
  Subproject Path: CordovaLib
  Android project created with cordova-android@6.1.2
  Discovered plugin "cordova-plugin-whitelist" in config.xml. Adding it to the project
  Fetching plugin "cordova-plugin-whitelist@1" via npm
  Installing "cordova-plugin-whitelist" for android
  
             This plugin is only applicable for versions of cordova-android greater than 4.0. If you have a previous platform version, you do *not* need this
  plugin since the whitelist will be built in.

构建项目

第一次构建可能有点慢，因为需要配置Gradle

• 先看看项目结构

  E:\Cordova\CordovaWindows>ls
  config.xml  hooks  platforms  plugins  www

  2

  • 配置文件 config.xml
  • 关联文件 hooks
  • android项目 platforms
  • 插件库 plugins
  • web项目 www

• 构建项目

  • cordova build android

• 构建效果

E:\Cordova\CordovaWindows>cordova build android
ANDROID_HOME=E:\64androidstudio\Android\Sdk
JAVA_HOME=E:\JDK
Subproject Path: CordovaLib
Starting a new Gradle Daemon for this build (subsequent builds will be faster).
Incremental java compilation is an incubating feature.

• 
  
• 运行项目
  
  • cordova run android
  • 运行之后提示 No target specified, deploying to device '192.168.237.101:5555'.
    

这里我开了一个Genymotion模拟器，上面是分配的设备，当然用真机效果当然是最好的。
这时候已经可以将platforms下的android导入Android Studio运行了，因为它已经是一个独立项目了

配置项目

前面在命令行操作有诸多不便，那么接下里既然项目都可以运行了，那就可以直接去项目配置
