cordova跨平台app开发01_创建项目、桌面图标、启动图配置

视频地址:http://t.cn/RacnKeB

安装cordova

1.     下载安装node.js(js的运行环境),安装时勾选npm(js包的管理工具)。
2、下载安装git(配置好环境变量)。
3、在cmd控制台,使用npm安装cordova。

npm install -g cordova

创建cordova项目

$ cordova create hello com.example.hello HelloWorld

第一个参数hello指定项目创建的目录

第二个参数com.example.hello指定项目的包名,您也可以在config.xml中修改

第三个参数 HelloWorld 指定应用程序显示的名称

如图1-1所示,成功创建了一个cordova项目,项目的地址为D:\phonegapProject\hello

创建出来的工程目录如下图所示

添加平台

后续的命令都需要在cordova工程目录下进行,所以先进到工程根目录

    $ cd hello

添加目标平台,添加平台前确认已经安装好相关平台的SDK

添加目标平台,以下命令行添加了ios和Android平台中

    $ cordova platform add ios
    $ cordova platform add amazon-fireos
    $ cordova platform add android
    $ cordova platform add blackberry10
    $ cordova platform add firefoxos

打包App

创建cordova工程的时候,生成的www文件夹为前端工程的放置的位置,目录基于web应用架构,如下图所示:

index.html为混合App的入口,一些初始化要放在www/js/index.js文件中的deviceready中。前端工程开发完成后就可以打包成对应各平台的App了。

cordova build

可以打包指定的平台

cordovabuild ios
cordovabuild adndroid

运行app

真机运行

$ cordova run android

模拟器运行

$ cordova emulate android

app图标设置

修改config.xml

下面的配置应用于所有平台

为每个平台还可以单独配置,以适合不同分辨率。
