{//-------------------------------Cordova Plugin 插件开发------------------
{//1. helloworld
> cordova create hello
> cd hello
> dir /*目录如下
config.xml: // 配置文件
hooks目录: //存放自定义cordova命令的脚本文件。每个project命令都可以定义before和after的Hook，比如：before_build、after_build。Hook可以采用任何编程语言来写，Cordova CLI采用的是Node.js，所以一般都是用它来写.
platforms目录: //各个平台的原生代码工程，不要手动修改，因为在build的时候会被覆盖
plugins目录: //插件目录（cordova提供的原生API也是以插件的形式提供的）。
www目录: //源代码目录，.html为应用的入口文件
*/
在 www目录下创建 hello.html /*并输入下面内容
<!DOCTYPE HTML>
<html>
<head>
<title>HelloWorld1</title>
</head>
<body>
<h1>Hello World</h1>
<p>This is a sample Cordova application</p>
</body>
</html>
*/
修改config.xml，把src属性改为hello.html，//修改启动页面为hello.html
> cordova platform add browser
> cordova platform add android@6.0 --save
> cordova build android
用Android Studio 导入该项目运行
}
{//2. "dialogs" 弹出提示框
> cordova plugin add cordova-plugin-dialogs
修改 hello.html内容为 /*
<!DOCTYPE HTML>
<html>
<head>
<script src="cordova.js" type="text/javascript" charset="uft-8"></script> // 加载了核心的Cordova API基本库
<script type="text/javascript" charset="utf-8">
function onBodyLoad() {
document.addEventListener("deviceready", onDeviceReady, false); //注册了deviceready事件的监听器为onDeviceReady函数
}
function onDeviceReady() { //当改onDeviceReady被调用时，输出提示信息
navigator.notification.alert("Cordova API alert Message "); //调用cordova api前需添加其对应的插件例如 dialogs
}
</script>
<titile> use cordova api</title>
</head>
<body onload="onBodyLoad()"> //定义了body的 onload事件关联到onBodyLoad处理函数
<h1>use cordova api</h1>
<p>use cordova api demo</p>
</body>
</html>
*/
> cordova build android
用Android Studio 导入该项目运行
}
{//3. "device" 获取设备硬件信息
> cordova plugin add cordova-plugin-device
修改 hello.html内容为 /*
<!DOCTYPE HTML>
<html>
<head>
<script src="cordova.js" type="text/javascript" charset="uft-8"></script>
<script type="text/javascript" charset="utf-8">

<p id="appInfo">Waiting for Cordova Initialization to complete</p> //注意如果前面不添加cordova-plugin-device插件成功，将一直显示该信息
</body>
</html>
*/
> cordova build android
用Android Studio 导入该项目运行
}
{//4. "camera" 实现最简获取camera图片
> cordova plugin add cordova-plugin-camera
> cordova plugin add cordova-plugin-console //想看到console.log的信息，必须要安装此插件
更改config.html /*
<content src="camera.html" />
*/
