打开本地flash webview open swf

想打开flash文件，必须装有flash插件。android手机上装Adobe Flash Player .APK才能打开显示flash。

可以单独成为android工程，也可以打包成jar，放到unity调用。

单独android工程需把swf文件放到assets文件夹里

MainActivity.class

package com.example.openswf_jar;import java.util.List;import android.net.Uri;import android.os.Bundle;import android.os.Handler;import android.annotation.SuppressLint;import android.app.Activity;import android.app.ProgressDialog;import android.content.Intent;import android.content.pm.PackageInfo;import android.content.pm.PackageManager;import android.graphics.Color;import android.util.Log;import android.view.Menu;import android.webkit.WebChromeClient;import android.webkit.WebSettings;import android.webkit.WebSettings.PluginState;import android.webkit.WebView;public class MainActivity extends Activity {private WebView mWebView;private Handler mHandler=new Handler();private String mFlashFilePath;private ProgressDialog mProgressDialog;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);mWebView=(WebView)findViewById(R.id.webview);setTitle("flash播放器");setTitleColor(Color.RED);WebSettings setting=mWebView.getSettings();setting.setPluginState(PluginState.ON);setting.setJavaScriptEnabled(true);Intent intent = getIntent();mFlashFilePath = intent.getStringExtra("url");if(mFlashFilePath == null)mFlashFilePath = "file:///android_asset/flash.swf";try {Thread.sleep(500);// 主线程暂停下，否则容易白屏，原因未知} catch (InterruptedException e) {// TODO 自动生成的 catch 块e.printStackTrace();}mProgressDialog=ProgressDialog.show(this, "请稍等...", "加载flash中...", true);mWebView.setWebChromeClient(new WebChromeClient(){@Overridepublic void onProgressChanged(WebView view, int newProgress) {// TODO Auto-generated method stubsuper.onProgressChanged(view, newProgress);System.out.println("newProgress:"+String.valueOf(newProgress));if(newProgress==100){new Handler().postDelayed(new Runnable() {@Overridepublic void run() {// TODO Auto-generated method stubmProgressDialog.dismiss();}}, 500);}}});if(checkinstallornotadobeflashapk()){Log.i("mainactivity","OPENSWF"+mFlashFilePath);mWebView.loadUrl(mFlashFilePath);}else{installadobeapk();}}@Overridepublic boolean onCreateOptionsMenu(Menu menu) {// Inflate the menu; this adds items to the action bar if it is present.getMenuInflater().inflate(R.menu.main, menu);return true;}//退出时关闭flash播放@Overrideprotected void onDestroy() {// TODO Auto-generated method stubsuper.onDestroy();mWebView.destroy();this.finish();System.gc();}//按下Back按键时关闭flash播放@Overridepublic void onBackPressed() {// TODO Auto-generated method stubmWebView.destroy();this.finish();System.gc();super.onBackPressed();}//后台运行@Overrideprotected void onUserLeaveHint() {// TODO Auto-generated method stubmWebView.destroy();this.finish();System.gc();super.onUserLeaveHint();}//检查机子是否安装的有Adobe Flash相关APK private boolean checkinstallornotadobeflashapk() {PackageManager pm = getPackageManager();List<PackageInfo> infoList = pm.getInstalledPackages(PackageManager.GET_SERVICES);for (PackageInfo info : infoList) {if ("com.adobe.flashplayer".equals(info.packageName)) {return true;}}return false;}//安装Adobe Flash APK@SuppressLint("JavascriptInterface") private void installadobeapk() {mWebView.addJavascriptInterface(new AndroidBridge(), "android");mWebView.loadUrl("http://app.mi.com/detail/188");}private class AndroidBridge {public void goMarket() {mHandler.post(new Runnable() {public void run() {Intent installIntent = new Intent("android.intent.action.VIEW");installIntent.setData(Uri.parse("market://details?id=com.adobe.flashplayer"));startActivity(installIntent);}});}}}

想加入到unity中，就要写以下内容。把swf文件放到StreamingAssets文件夹里。

UnityCall.class

package com.example.openswf_jar;import android.content.Context;import android.content.Intent;public class UnityCall {public void U3DCallOpenSWF(Context unityActivity, String url){Intent intent = new Intent(unityActivity,MainActivity.class);intent.putExtra("url", url);unityActivity.startActivity(intent);}}

在unity中写代码

<span style="white-space:pre"></span>private AndroidJavaObject javaObj = null;private AndroidJavaObject GetJavaObject(){if (javaObj == null){javaObj = new AndroidJavaObject("com.example.openswf_jar.UnityCall");}return javaObj;}void OpenSWF(){AndroidJavaClass jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer");AndroidJavaObject jo = jc.GetStatic<AndroidJavaObject>("currentActivity");GetJavaObject().Call("U3DCallOpenSWF",jo,"file:///android_asset/flash.swf");}

activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent" >    <WebView        android:id="@+id/webview"         android:layout_width="fill_parent"        android:layout_height="fill_parent"        android:layout_centerInParent="true" /></RelativeLayout>
