4399支付SDK供flash游戏使用ANE的使用

2017-11-14 607

 这两天对Flash游戏如何去接入android平台的SDK做了下研究，做了4399的支付SDK接入的工作，这里与大家分享下。


一、ANE的介绍

（网络描述也是一大堆，这里描述摘自http://blog.csdn.net/myquark/article/details/7904030）


Adobe AIR Native Extension，Adobe AIR的本地扩展，简称ANE。什么叫本地扩展？因为Adobe AIR是跨平台的一个运行时，可以在Windows，Mac，Android，iOS等系统上跑，正是因为其跨平台，所以它本身的功能就有局限性，不可能面面俱到；换句话来说，比如我们想在flash程序中调用一下系统的消息通知功能，但是AIR并没有这个功能，那么怎么办？这就要根据本地平台写段代码，让AIR委托本地平台去执行这段代码，这样就达到了拓展AIR程序的功能。换个角度来看问题，就好像系统有个dll文件，AIR可以去直接调用这个dll文件（这只是一个比方而已，让大家更容易理解，实际上AIR不能直接调用dll文件）。我们可以开发一个Android手机振动程序，然后打包成ANE，这样运行在AIR中的程序就可以调用写好的手机程序了。有了ANE机制，我们就可以开发很多Flash无法完成但是却可以使用的功能。


二、ANE开发步骤

 ANE的生成需要两个步骤，一个是生成本地的jar包，一个生成SWC库文件，最后进行编译合成。

  本文开发工具为fb 4.7 与eclipse为主


1、创建ane Android项目，生成本地jar包


准备工作

1）在eclipse中创建一个android的项目，假定命名为4399PaySDKANE_JAVA；

2) 将需要依赖的包(4399PaySdk.jar和FlashRuntimeExtensions.jar)添加到项目的libs目录下。

3）在项目属性中-java build path-Libraries下，添加以下

4399PaySdk.jar(4399的支付sdk包，在http://opensj.4399api.net/dev/downloadExchange可以下载到)

FlashRuntimeExtensions.jar(该包在E:\softinstall\ADOBE\Adobe Flash Builder 4.7\sdks\4.6.0\lib\android可找到)

4）在项目属性 - Java Build Path - Order and Export 下，将游戏 SDK 及其依赖的 JAR 包（4399PaySdk.jar）打上勾，确保能够被输出到生成的 JAR 包中；

 

准备工作有些多哈。接下来正式进入开发。


编码部分：


1、编写 FREContext 的派生类（YJPaymentApiContext.java）

package  com.sj4399.pay.ane;
import  java.util.HashMap;
import  java.util.Map;
import  com.adobe.fre.FREContext;
import  com.adobe.fre.FREFunction;
public  class  YJPaymentApiContext  extends  FREContext {
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
     @Override
     public  void  dispose() {
     }
     @Override
     public  Map<String, FREFunction> getFunctions() {
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
         return  null ;
     }
}

空的文件先不管。


2、编写 FREExtension 的派生类（如：YJPaymentApiExtension），在 createContext 方法中创建 YJPaymentApiContext的实例，并作为该方法的结果值返回。

package  com.sj4399.pay.ane;
import  com.adobe.fre.FREContext;
import  com.adobe.fre.FREExtension;
public  class  YJPaymentApiExtension  implements  FREExtension {
     @Override
     public  FREContext createContext(String arg0) {
         // TODO Auto-generated method stub
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
         return  new  YJPaymentApiContext();
     }
     @Override
     public  void  dispose() {
         // TODO Auto-generated method stub
     }
     @Override
     public  void  initialize() {
         // TODO Auto-generated method stub
     }
}


3、编写一系列 FREFunction 的派生类（如：YJFInit，YJFLogin……等），以实现每一个接口，每个接口方法用一个 FREFunction 派生类实现；


以YJFInit.java为例

package  com.sj4399.pay.ane;
import  com.adobe.fre.FREContext;
import  com.adobe.fre.FREFunction;
import  com.adobe.fre.FREObject;
import  com.sj4399.pay.YjPaymentApi;
public  class  YJFInit  implements  FREFunction {
     private  static  final  String TAG =  "YJFInit" ;
     @Override
     public  FREObject call(FREContext context, FREObject[] args) {
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
         YJPaymentApiContext yjac = (YJPaymentApiContext)context;
         YjPaymentApi.getInstance().init(yjac.getActivity());
         return  null ;
     }
}


我们通过

1
context.dispatchStatusEventAsync(callbackString,  "" );

进行回调给as3端。编写完其他接口类即可。


4、修改 YJPaymentApiContext的 getFunctions 方法，将实现的每一个 FREFunction 派生类添加到函数集合中，该函数集合作为该方法的结果值返回；此函数集合即承担接口调用职责

import  com.adobe.fre.FREFunction;
public  class  YJPaymentApiContext  extends  FREContext {
                                                                                                                                                                                                                                                                                                                                                                                                                                                    
     @Override
     public  void  dispose() {
     }
     @Override
     public  Map<String, FREFunction> getFunctions() {
         Map<String, FREFunction> mapFunc =  new  HashMap<String, FREFunction>();
         mapFunc.put( "getUser" ,  new  YJFGetUser());
         mapFunc.put( "charge" ,  new  YJFCharge());
         mapFunc.put( "destoryLogin" ,  new  YJFLogout());
         mapFunc.put( "openLogin" ,  new  YJFLogin());
         mapFunc.put( "init" ,  new  YJFInit());
                                                                                                                                                                                                                                                                                                                                                                                                                                                           
         return  mapFunc;
     }
}


5、编写 ant 配置文件 build.xml，编译导出 JAR 包

这样就完成了本地jar包的生成工作了。


2、创建flex库项目，生成swc库


准备工作:


1）创建项目

2）属性设置

wKiom1Mfyw-wm420AAKqRUbLYTw291.jpg


编码部分：


这边使用单例模式，创建actionscript代码

         /**

          */
         public  function  get  code():  int  {
             return  _code;
         }

          * @return
          *
          */
         public  function  get  data():  Object  {
             return  _data;
         }}
}

package  com.sj4399.pay.ane
{
     public  class  Constants
     {
         public  static  const  EVENT_TYPE_4399PAYSDK_CALLBACK =  "4399_pay_sdk_callback" ;
                                                                                                                                                                                                                                                                          
         public  static  const  CB_LOGIN: String  =  "login" ;
         public  static  const  CB_LOGOUT: String  =  "logout" ;
         public  static  const  CB_CHARGE: String  =  "charge" ;
                                                                                                                                                                                                                                                                          
                                                                                                                                                                                                                                                                          
         public  static  const  STATUS_LOGIN_COMPLETE: int  = - 1 ; //登录完成
         public  static  const  STATUS_LOGIN_CANCEL: int  = - 2 ;  //取消登录
         public  static  const  STATUS_LOGOUT_COMPLETE: int  = - 3 ;  //取消登录
         public  static  const  STATUS_CHARGE_COMPLETE: int  = - 4 ;  //充值完成
         public  static  const  STATUS_CHARGE_CANCEL: int  = - 5 ;  //取消充值
                                                                                                                                                                                                                                                                          
     }
}

编译在bin目录下可以看到swc库文件。


3、生成ANE

  拷贝生成的本地jar文件 与swc文件到要创建ANE的目录下

wKioL1MfzI_ji7T2AADbEQgvUJM369.jpg

这里我们可以看到有个extension.xml，这个就是用于as3代码里面的的拓展标识，用于as3调用jar包中的函数，里面内容是

< extension  xmlns = "http://ns.adobe.com/air/extension/2.5" >
     < id >com.sj4399.pay.ane.android</ id >
     < versionNumber >1</ versionNumber >
     < platforms >
         < platform  name = "Android-ARM" >
             < applicationDeployment >
                 < nativeLibrary >4399PaySDKANEJava.jar</ nativeLibrary >
                 < initializer >com.sj4399.pay.ane.YJPaymentApiExtension</ initializer >
                 < finalizer >com.sj4399.pay.ane.YJPaymentApiExtension</ finalizer >
             </ applicationDeployment >
         </ platform >
     </ platforms >
</ extension >

 

signature.p12是air生成的密钥，相信air游戏开发者都清楚这个内容。


以解压的方式打开SWC，解压其中的library.swf到Android-ARM文件夹中。

将jar包和第三方所需要的res资源文件拷贝到Android-ARM中，如图

wKiom1MfzlOiDSo2AACD6pc1nJU317.jpg


这里都做好了，接下来就是生成ANE了，我们编写一个批处理文件

@REM 打包 .ane
SET SWC_FILE=4399PaySDK_ANE_AS.swc
SET ANE_FILE=4399PaySDK.ane
SET JAR_FILE=4399PaySDKANEJava.jar
SET FLEX_ADT_CMD=java -jar  "E:\softinstall\ADOBE\Adobe Flash Builder 4.7\sdks\4.6.0\lib\adt.jar"
%FLEX_ADT_CMD% -package -tsa none -storetype pkcs12 -keystore signature.p12 -storepass 123456 -target ane %ANE_FILE% extension.xml -swc %SWC_FILE% -platform Android-ARM -C Android-ARM .
pause


好了，这样就可以生成我们的所需要的ANE了.至于如何调用相信大家都知道，这里就不多说了。

如何使用GNS3和Cisco IOU搭建路由交换实验-IOU篇

前面介绍了GNS3的概念，安装，配置和使用，本篇将介绍怎么利用GNS3配置IOU从而实现使用GNS3和Cisco IOU搭建路由交换实验。 由于本篇篇幅较长，所以先过一下大纲： 1. IOU模拟环境介绍 2. IOU软件环境的准备 3. VMware虚拟机的安装、导入和配置 4. IOU镜像的上传 5. GNS3的配置 6. IOU模拟环境的实现 IOU模拟环境介绍 IOU即IOSOnUnix，最初是由思科内部人员开发来测试IOS的平台，后来流传到互联网经网友改进有了后来的WEB IOU。而GNS3从1.0版本后就开始整合了IOU，GNS3的IOU相比WEB IOU在拓扑的构建方面方便灵活了很多。IOU的后端运行环境是基于Unix的操作系统，该系统可以运行在Oracle VirtualBox或者VMware的虚拟机上。由于是把IOU镜像运行在Unix系统上，所以对物理机资源的占用非常低。 IOU的运行环境如上图所示：IOS运行在Dynamips模拟的GNS3本地服务器中，GNS3以C/S的web模式通过127.0.0.1:8000访问运行在物理机上的GNS3本地服务器；IOU镜像运行在...

【读书笔记《Android游戏编程之从零开始》】8.Android 游戏开发常用的系统控件（系统控件常见问题）

Android 中常用的计量单位 Android有时候需要一些计量单位，比如在布局Layout文件中可能需要指定具体单位等。 常用的计量单位有：px、dip(dp)、sp，以及一些不常用的pt、in、mm。下面详细介绍下这些计量单位之间的区别和联系。 in：英寸（长度单位）； mm：毫米(长度单位)； pt：磅/点，1/72英寸（一个标准的长度单位）； sp:全名 scaled pixels-best for text size,放大像素，与刻度无关，可以根据用户的字体大小就行缩放，主要用来处理字体的大小； px：屏幕中的像素； dip(dp)：设备独立像素，一种基于屏幕密度的抽象单位；因为不通设备中有不同的显示效果，所以为了解决在不通分辨率手机上运行不至于相差太大的问题，引入了dip计量单位，这种计量单位与移动设备硬件无关。 说道密度，这里简单介绍下。手机密度值（Density）表示每英寸有多少个显示点，与手机的分辨率是两个概念，但是分辨率与密度之间又互相关联，两者转换公式为： 密度值是120，屏幕实际分辨率为：240px×400px（两个点对应一个分辨率）； 密度值是160，屏幕实...
