android - 无法在 Android Web View 中查看视频

Question

我的网页使用 html5 视频标签嵌入了视频文件。

我有一个嵌入式 Web 服务器 (NanoHTTPD) 正在运行，它可以从文件系统为我的文件提供服务。其他一切正常，但当我点击播放 HTML5 视频时。它给出了以下错误并且没有播放视频

媒体播放器转到内容解析器，该解析器尝试仅加载内容方案的文件。我的uri是http方案。

我的 WebView 非常简单。

WebSettings webViewSettings = webView.getSettings();
    webViewSettings.setJavaScriptEnabled(true);
    //webViewSettings.setJavaScriptCanOpenWindowsAutomatically(false);
    //webViewSettings.setSupportMultipleWindows(true);
    webViewSettings.setPluginState(PluginState.ON);
    //webViewSettings.setMediaPlaybackRequiresUserGesture(false);
    webViewSettings.setAllowFileAccess(true);
    webView.setSoundEffectsEnabled(true);
    //webViewSettings.setSupportZoom(true);
    //WebView.setWebContentsDebuggingEnabled(true);

    webView.setWebViewClient(new CustomWebViewClient());
    webView.setWebChromeClient(mWebChromeClient);

干杯，索拉夫

Answer 1

您需要使用 loadDataWithBaseURL。

看这个: https://stackoverflow.com/a/24592012/850347

不要这样做:

mContentWebView.loadDataWithBaseURL(null, webViewContentString,
        "text/html", "UTF-8", null);

改为这样做:

//veryVeryVery important for playing the videos!
mContentWebView.loadDataWithBaseURL(theBaseUrl, webViewConentString,
        "text/html", "UTF-8", null);
