我有一个（客户）网站，它使用 js brightcove 播放器来呈现 html5 视频。（阅读：我无法编辑网站本身）

在移动 Chrome 中，视频可以正常工作，一切都很好。但是在我的 Android 应用程序中，使用呈现完全相同页面的 WebView 无法播放视频。

我已经阅读了许多类似的 SO 问题，并确保已完成以下操作：

  • 关闭网络视图插件（关闭 Flash），以确保使用的是 html5 视频而不是 Flash 版本。
  • javascript显然已启用
  • webchromeclient 安装在 web 视图上。
  • 覆盖 webchromeclient 中的 onShowCustomView （不幸的是，它从未被调用）
  • 为活动打开硬件加速

有些帖子建议手动调用视频的 play() 方法，这不是一个好主意，但是无论如何都不可能，因为brightcove播放器的视频标签在iframe中，无法获取它通过javascript。

到目前为止，我已经没有什么想法了，问题可能出在哪里或在哪里。任何建议都非常感谢。LogCat 中唯一相关的日志消息是：

这个答案可能对你的问题有答案。

我尝试过使用 API 16 (4.1 JB)，但这个示例 Brightcove 视频仅在全屏时播放。

您可以在全屏模式下强制启动视频，并在用户要求或视频结束时退出。

我相信这是由 WebView 类本身引起的，因为 4.1 JellyBean 是从普通的 Android 浏览器到 Google Chrome 的过渡。虽然较新的 4.1 版本的默认浏览器变为 Chrome，但 WebViews 仍在使用旧引擎，因此无法正确呈现视频。

另一种解决方案是重定向用户并强制他使用他的浏览器（如果你幸运的话，它是 chrome 并且将显示视频）。

我在 android 中播放 html5 视频，这对我有用：

我的活动

public class Test extends Activity {

    HTML5WebView mWebView;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        mWebView = new HTML5WebView(this);

        if (savedInstanceState != null) {
            mWebView.restoreState(savedInstanceState);
        } else {    
            mWebView.loadUrl("http://player.vimeo.com/video/27244727");
        }

        setContentView(mWebView.getLayout());
    }

    @Override
    public void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
        mWebView.saveState(outState);
    }

    @Override
    public void onStop() {
        super.onStop();
        mWebView.stopLoading();
    }

    @Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {

        if (keyCode == KeyEvent.KEYCODE_BACK) {
            if (mWebView.inCustomView()) {
                mWebView.hideCustomView();
            //  mWebView.goBack();
                //mWebView.goBack();
                return true;
            }

        }
        return super.onKeyDown(keyCode, event);
    }
}

这可能无济于事，但您应该只下载 Firefox for Android 的源代码并将其捆绑到您的应用程序中，如果它能让您的生活更轻松。我为一个需要 websockets 并且我们需要向后兼容性的项目做了这个。
