国内的移动Web开发平台Rexsee开源了，使用Web开发模式就可以实现Android移动应用。社区可以查看全部的扩展API说明与开发源码。http://www.rexsee.com
学习了一篇入门教程，介绍如何将Flash游戏移植到Android手机上，并可以通过虚拟键盘或者方向传感器解决操控问题。所有代码是用HTML和JS写的，包括全部HTML，总共只有100多行。步骤如下：
1. 准备键盘图片，这里用到了6个键，左、右、空格（跳跃）、退出、消息和Rexsee市场键，Rexsee提供了几套现成的键可以下载。将键的图片放到asset/keyboard/default/文件夹中，这样用"keyboard/default"来指定theme参数即可，否则要用放图片的文件夹的完整路径（本地SD卡或网络地址均可）来制定theme参数。文件名就是键值，后缀名是.png
2. 将美羊羊卡丁车的swf文件放在asset/文件夹中
3. 将横幅图片（这里是banner.png）和启动按钮图片（这里是startNow.png）放在asset/文件夹中
4. 当然还有图标要放在res中，还要将string.xml中的首页地址设为file:///android_asset/index.html。这是唯一的一个程序文件，100多行。
5. 这是离线版的，所以要下载Rexsee的JAR包，自己用Eclipse编译，如果嫌麻烦，可以在线编译一个首页地址指向服务器某个网页地址，然后将下面的index.html的代码放在这个文件中（有些路径要改，比如图片什么的），如果也想离线玩，可以在首次载入后将swf文件和图片自己或者用rexseeClient下载到本地。当然也可以不下载，就在线玩。
先看一下res/values/string.xml
- HTML code
<?xml version="1.0" encoding="utf-8"?><resources><string name="app_name">美羊羊卡丁车</string><string name="app_home">file:///android_asset/index.html</string><string name="rexsee_home">http://www.rexsee.com/flash/index.php</string></resources>
在看一下AndroidManifest.xml
- HTML code
<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android" package="MeiYangYangKaDingChe.rexsee" android:versionCode="1" android:versionName="1.0"><supports-screens android:largeScreens="true" android:normalScreens="true" android:smallScreens="true" android:anyDensity="true" /><application android:icon="@drawable/icon" android:label="@string/app_name" android:theme="@android:style/Theme.NoTitleBar"><activity android:name="rexsee.activity.RexseeActivity" android:configChanges="orientation|keyboardHidden" android:launchMode="singleTop"><intent-filter><action android:name="android.intent.action.MAIN" /><category android:name="android.intent.category.LAUNCHER" /></intent-filter></activity></application><uses-permission android:name="android.permission.INTERNET"/><uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/></manifest>
最后是asset/index.html源的代码
