1.准备工作
1.1 编写你的应用
你可以通过JavaScript、Css和HTML来编写 SPA(单页应用程序),页面的入口为index.html。也可以使用Mobile Framework,如 Sencha Touch、 jQtouch、 JQuery Mobile。
1.2 配置config.xml文件
1.2.1 配置包名
通过widget标签的id属性可以配置,它是应用的唯一标记。
1.2.2 配置版本
通过widget标签的version属性可以配置。
1.2.3 配置程序名
通过name标签进行配置,如:
<name>Demo</name>
1.2.4 配置程序icon
通过icon标签可以配置,如:
<icon src="icon.png"/>
把icon图标放到和index.html文件相同的目录即可,大小可以为114*114px。
1.3 调用手机功能
该编译环境使用了开源项目 PhoneGap,因此调用手机API可以参见:
- PhoneGap中文文档
- PhoneGap英文文档
例如要调用手机摄像头功能,需要在JavaScript中添加如下代码:
navigator.camera.getPicture(onSuccess, onFail);function onSuccess(imageData) { //在页面中显示拍照的图片,也可以上传到服务器 var image = document.getElementById('myImage'); image.src = "data:image/jpeg;base64," + imageData;}function onFail(message) { alert('Failed because: ' + message);}
2.开始编译
该编译环境可以将基于JavaScript、Css和HTML创建的应用实现跨平台,目前我们只支持Android和IOS平台。
2.1 上传你的应用
你的应用中可以包含以下内容:
- index.html(必须)
- config.xml(必须)
- icon.png:应用程序图标(必须)
- 其它资源文件: JavaScrpit、Css文件、图片、多媒体文件等等
最后将你的应用压缩为zip格式的文件进行上传。
2.2 进行编译
选择要编译的平台进行编译,该过程要等待几分钟。
3.下载安装
编译好之后就可以进行下载安装了。

The future trends of HTML are semantics and web components, the future trends of CSS are CSS-in-JS and CSSHoudini, and the future trends of JavaScript are WebAssembly and Serverless. 1.
