BigBlueButton URL未在Android WebView中加载

编程问答 2022-06-13

问题描述

我对我的一个应用程序有一个要求，该应用程序可在WebView中打开BigBlueButton链接。网址是：

https://bbb.odin-health.com/bigbluebutton/api/join?fullName=Testdevice&meetingID=1600182496839&password=5FvAjuRt&checksum=b315e70fdabd4f3b56a1e33e500d0d259290653c

当尝试在Webview中加载此网址时，它会显示白页或空白页。这是代码

WebSettings webSettings = webview.getSettings();
    webview.setWebViewClient(new MyWebViewClient());
    webSettings.setSupportZoom(true);
    webSettings.setBuiltInZoomControls(true);     
  

    webSettings.setUserAgentString("Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML,like Gecko) Chrome/81.0.4044.117 Safari/537.36");
    webSettings.setSupportMultipleWindows(true);
    webSettings.setJavaScriptCanopenWindowsAutomatically(true);
    webSettings.setPluginState(WebSettings.PluginState.ON);
    webSettings.setAppCacheMaxSize( 10 * 1024 * 1024 );
    webSettings.setAppCacheEnabled(true);
    String appCachePath = getActivity().getCacheDir().getAbsolutePath();
    webSettings.setAppCachePath(appCachePath);

    webSettings.setAllowFileAccess(true);
    webview.setLayerType(View.LAYER_TYPE_HARDWARE,null);
    webSettings.setMixedContentMode(
            WebSettings.MIXED_CONTENT_ALWAYS_ALLOW );

    webSettings.setJavaScriptEnabled(true);
    webSettings.setmediaplaybackRequiresUserGesture(false);


    webview.setWebChromeClient(mSWWebChromeClient);

    webview.loadUrl(getArguments().getString(Constants.BIGBLUEBUTTON_URL));

我在那里缺少什么吗？相同的网址在Device的Google Chrome浏览器中正常工作。

这是Logcat错误日志：

解决方法

android webview 使用用户代理发送请求不适合 bbb 默认配置。在 bbb 文档中。检查/usr/share/meteor/bundle/programs/server/assets/app/config/settings.yml，您将在其中看到浏览器（来自用户代理字符串）和最低版本。在那里添加您的 webviews 版本。
