当flash全屏打开时Android WebView为空白-ICS 4.0

我正在构建一个应用程序，它依赖于能够在网络视图中播放Flash，并且在Flash视频全屏播放之前，它已经发现一切都按照预期工作。请求全屏时，屏幕变黑，音频持续约5秒

我最初发现屏幕变白了，但采用了下面文章中的解决方案，从而移动了目标位置。

当全屏flash视频启动时，我在logcat中看到以下内容

08-11 15:09:47.435:V/VideoSurfaceView（23871）：表面处理

08-11 15:09:47.435:V/VideoSurfaceView（23871）：表面更改格式=842094169，宽度=480，高度=690

下面的答案参考了在浏览器中实现类似于BaseUI类的onShowCustomView。有一个非常类似的方法叫做showCustomView，我尝试在代码中添加BaseUI类的内容，令人惊讶的是，我成功地使代码编译并运行，但这并没有带来一点盲目的差异

提前感谢您的想法和帮助……

在进一步挖掘之后，我回答了我的问题，这让我进入了下一组问题，我将以单独的问题发布

以下代码将从网络视图全屏显示Flash，只要Flash不请求方向更改。它还中断了源webView，因为在对“指定的子级已具有父级”崩溃进行故障排除后，我被迫添加removeAllViews（）方法

另外，将实现WebView作为最终选项以允许从重写的WebChromeClient方法进行访问会中断需要访问此WebView的任何其他方法

public void startWebView(String url){
   final WebView mWebView = (WebView)findViewById(R.id.webview);
   final Context ctx = this;

        webSettings.setPluginState(WebSettings.PluginState.ON);
        webSettings.setJavaScriptEnabled(true);
        webSettings.setLoadWithOverviewMode(true);

        mWebView.requestFocusFromTouch();
        mWebView.setWebViewClient(new WebViewClient());

        mWebView.setWebChromeClient(new WebChromeClient(){
            protected WebView tempView;
            public void onShowCustomView(View view, int requestedOrientation, WebChromeClient.CustomViewCallback callback){
                super.onShowCustomView(view, callback);   
                if(Build.VERSION.SDK_INT >=14) {
                    if (view instanceof FrameLayout) {                  
                        mWebView.addView(view, new FrameLayout.LayoutParams(
                        ViewGroup.LayoutParams.MATCH_PARENT,
