Android：PhoneGap入门

PhoneGap是一能够让你用普通的web技术编写出能够轻松调用API接口和进入应用商店的HTML5应用开发平台。是唯一的一个支持7个平台的开源移动框架。它的优势是无以伦比的：开发成本低——据估算，至多Native App的五分之一！

• 兼容性:完全做到了Written Once，Run Everywhere!
• 标准化，PhoneGap采用W3C标准，Web App直接运行！
• 用JavaScript+HTM5。和iOS以及android的代码加XML没区别！
• 大众化移动互联网开发平台 了解更多
  • 轻量级架构，功能卓越的手机应用快速开发平台
  • 精确兼容系统 Andriod iPhone&iPad Symbain WM
  • 无成本开发，20%的开发周期，20%的升级维护成本
  • 完全不需要手机编程基础，只要会HTML就能做应用

 

一、PhoneGap环境配置

    1、打开Eclipse，新建一个Android项目。

    2、如果没有/libs目录，则创建，另外，创建一个/assets/www目录。

    3、从刚才下载的PhoneGap中复制phonegap.js 到/assets/www目录；

        从刚才下载的PhoneGap中复制phonegap.jar 到/libs目录；

        从刚才下载的PhoneGap中复制xml文到夹到/res 目录。

    4、对Eclipse的src文件夹中的主Java文件进行少量调整：

        将class的继承类由Activity 改为DroidGap；

        将 setContentView() 这一行替换为super.loadUrl(file:///android_asset/www/index.html);

        添加 import com.phonegap.*;

        移除import android.app.Activity;

 

注：

在这里你可能会遇到Eclipse找不到phonegap-1.0.0.jar的错误。在这种情况下，右键单击/libs文件夹找到Build Paths/ > Configure Build Paths。然后在Libraries标签页中添加phonegap-1.0.0.jar到项目中。如果Eclipse不是很稳定，你需要点击F5刷新一次项目。

5、给Manifest文件添加说明和权限：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46

<? xml version = "1.0" encoding = "utf-8" ?>   < manifest xmlns:android = "http://schemas.android.com/apk/res/android" android:windowSoftInputMode = "adjustPan"        package = "org.apache.cordova.example" android:versionName = "1.0" android:versionCode = "1" android:hardwareAccelerated = "true" >      < supports-screens          android:largeScreens = "true"          android:normalScreens = "true"          android:smallScreens = "true"          android:xlargeScreens = "true"          android:resizeable = "true"          android:anyDensity = "true"          />        < uses-permission android:name = "android.permission.CAMERA" />      < uses-permission android:name = "android.permission.VIBRATE" />      < uses-permission android:name = "android.permission.ACCESS_COARSE_LOCATION" />      < uses-permission android:name = "android.permission.ACCESS_FINE_LOCATION" />      < uses-permission android:name = "android.permission.ACCESS_LOCATION_EXTRA_COMMANDS" />      < uses-permission android:name = "android.permission.INTERNET" />      < uses-permission android:name = "android.permission.RECEIVE_SMS" />      < uses-permission android:name = "android.permission.RECORD_AUDIO" />      < uses-permission android:name = "android.permission.RECORD_VIDEO" />      < uses-permission android:name = "android.permission.MODIFY_AUDIO_SETTINGS" />      < uses-permission android:name = "android.permission.READ_CONTACTS" />      < uses-permission android:name = "android.permission.WRITE_CONTACTS" />        < uses-permission android:name = "android.permission.WRITE_EXTERNAL_STORAGE" />        < uses-permission android:name = "android.permission.ACCESS_NETWORK_STATE" />      < uses-permission android:name = "android.permission.GET_ACCOUNTS" />      < uses-permission android:name = "android.permission.BROADCAST_STICKY" />          < application android:icon = "@drawable/icon" android:label = "@string/app_name"          android:hardwareAccelerated = "true"          android:debuggable = "true" >          < activity android:name = "example" android:label = "@string/app_name"                  android:theme = "@android:style/Theme.Black.NoTitleBar"                  android:configChanges = "orientation|keyboardHidden|keyboard|screenSize|locale" >              < intent-filter >                  < action android:name = "android.intent.action.MAIN" />                  < category android:name = "android.intent.category.LAUNCHER" />              </ intent-filter >          </ activity >      </ application >        < uses-sdk android:minSdkVersion = "7" android:targetSdkVersion = "17" /> </ manifest >

 

二、编写Hello World代码

1、在 “/assets/www”目录中新建文件index.html。

2、index.html的代码如下：

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24

<! DOCTYPE html> < html >      < head >          < meta charset = "utf-8" />          < meta name = "format-detection" content = "telephone=no" />          < meta name = "viewport" content = "user-scalable=no, initial-scale=1, maximum-scale=1, minimum-scale=1, width=device-width, height=device-height, target-densitydpi=device-dpi" />          < link rel = "stylesheet" type = "text/css" href = "css/index.css" />          < title >Hello World</ title >      </ head >      < body >          < div class = "app" >              < h1 >Apache Cordova</ h1 >              < div id = "deviceready" class = "blink" >                  < p class = "event listening" >Connecting to Device</ p >                  < p class = "event received" >Device is Ready</ p >              </ div >          </ div >          < script type = "text/javascript" src = "cordova.js" ></ script >          < script type = "text/javascript" src = "js/index.js" ></ script >          < script type = "text/javascript" >              app.initialize();          </ script >      </ body > </ html >
