1、设置webview属性：

       webView.setWebChromeClient(new MyWebChromeClient());

        webSettings = webView.getSettings();

        webSettings.setJavaScriptEnabled(true);

        webSettings.setPluginState(WebSettings.PluginState.ON);

        webSettings.setUseWideViewPort(true); 

        webSettings.setAllowFileAccess(true); 

        webSettings.setSupportZoom(true); 

        webSettings.setLoadWithOverviewMode(true);

        webSettings.setCacheMode(WebSettings.LOAD_NO_CACHE);

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {

            webSettings.setMixedContentMode(WebSettings.MIXED_CONTENT_ALWAYS_ALLOW);

        }

        webSettings.setUseWideViewPort(true);

        webView.addJavascriptInterface(new JavaScriptObject(this), "android");

2、设置AndroidManifest.xml:

//开启硬件加速

3、关闭界面任在播放的问题：

@Overridepublic void onPause() {    super.onPause();    webView.onPause();    webView.pauseTimers();}@Overridepublic void onResume() {    super.onResume();    webView.resumeTimers();    webView.onResume();}@Overrideprotected void onDestroy() {    webView.destroy();    webView = null;    super.onDestroy();}
