通过androi官方文档,android是在2.1以后的版本开始支持flash视频播放的。 参见官方说明。

既然官方都不支持了,那我们再研究flash播放器就显得毫无必要,所以我们的解决方案主要是靠android提供的WebView,可浏览网页的内置组件来播放flash。

adobe官方关于OBJECT tag syntax说明 上面有详细的说明,我这里就不详细解释了,如果有不明白的,欢迎联系。

了解清楚解决方案中的核心用法之后继续下一步就水到渠成了。

主要分为以下几个步骤:

  1. 创建android项目
  2. 创建一个用于播放flash的activity ``` package com.ftxgame.ftxplatform.activity;

import java.lang.reflect.InvocationTargetException; import java.lang.reflect.Method; import java.util.List;

import android.annotation.SuppressLint; import android.app.Activity; import android.app.ActivityManager; import android.app.AlertDialog; import android.app.ProgressDialog; import android.content.Context; import android.content.DialogInterface; import android.content.Intent; import android.content.pm.PackageInfo; import android.content.pm.PackageManager; import android.os.Bundle; import android.os.Handler; import android.util.DisplayMetrics; import android.util.Log; import android.view.View; import android.view.Window; import android.view.WindowManager; import android.webkit.WebChromeClient; import android.webkit.WebSettings; import android.webkit.WebSettings.PluginState; import android.webkit.WebView; import android.webkit.WebViewClient; import android.widget.FrameLayout;

import com.ftxgame.ftxplatform.R; import com.umeng.analytics.MobclickAgent;

@SuppressLint(“NewApi”) public class FTXVideoActivity extends Activity {

``` 一个兼容android2.1以上系统的flash播放解决方案就完成了。

后面经过我的*全面兼容性测试*,可能会有以下问题: 1. android系统自身已经安装adobe flash player 11或之前版本,在android4.1之前的老系统上可能是正常的,但是在新系统上会存在问题,或许还包括4.0系统,因为资源问题,我就无法测试到位,希望有朋友能给我测试的反馈。 2. android4.0以上系统全屏支持不够好,android2.3.5基本上可以说是完美播放。 3. android2.2系统是不支持flash11.1的,所以我们在提示播放的时候要安装对应的版本。
