我无法在Android网页视图上播放视频.

我已将html和视频文件保存在我的assets文件夹中.

每当我加载html文件时,它都会给我错误

05-01 12:31:16.092: E/MediaResourceGetter(17241): Unable to read file: file:///android_asset/MediaBook2%20(2)/2B952499A0E681.mp4

每当我按下播放按钮时,我都会收到以下错误

05-01 12:31:23.680: E/chromium(17241): [ERROR:webmediaplayer_android.cc(328)] Not implemented reached in virtual void content::WebMediaPlayerAndroid::setRate(double)
05-01 12:31:23.710: E/MediaPlayer(17241): error (1,-2147483648)
05-01 12:31:23.710: E/MediaPlayer(17241): Error (1,-2147483648)

能够加载任何远程视频并运行,但问题是我从资源文件夹加载本地视频
用于加载文件和设置Web视图的代码

@Override
protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);

    // Remove title bar
    requestWindowFeature(Window.FEATURE_NO_TITLE);

    setContentView(R.layout.activity_webview);
    mContentView = (LinearLayout) findViewById(R.id.linearlayout);
    // Keep the webview setup ready
    setupWebView();


}

public void setupWebView()
{
    webView = (WebView) findViewById(R.id.webView);
    // progressBar = (ProgressBar) findViewById(R.id.progressBarForWebView);

    WebSettings webViewSettings = webView.getSettings();
    webViewSettings.setJavaScriptEnabled(true);
    webViewSettings.setJavaScriptCanOpenWindowsAutomatically(true);
    webViewSettings.setPluginState(PluginState.ON);
    webView.getSettings().setAllowFileAccess(true);
    webView.setSoundEffectsEnabled(true);
    webView.setWebViewClient(new SLCWebViewClient());
    webView.setWebChromeClient(new WebChromeClient());
    loadContentsInWebView();

}
public void loadContentsInWebView()
    {

        String localURL = "file:///android_asset/MediaBook2 (2)/SampleForVideo.html";
        logger.debug("WebView URL: {}",localURL);
        try {
            webView.loadUrl(localURL);
        }
        catch (Exception e) {
            e.printStackTrace();
            logger.error("Error while loading url",e);
        }
    }
    private class SLCWebViewClient extends WebViewClient
{
    @Override
    public boolean shouldOverrideUrlLoading(WebView view,String url)
    {
        view.setWebChromeClient(new WebChromeClient()
        {

            private View mCustomView;

            @Override
            public void onShowCustomView(View view,WebChromeClient.CustomViewCallback callback)
            {
                // if a view already exists then immediately terminate the new one
                if (mCustomView != null) {
                    callback.onCustomViewHidden();
                    return;
                }

                // Add the custom view to its container.
                mCustomViewContainer.addView(view,COVER_SCREEN_GRAVITY_CENTER);
                mCustomView = view;
                mCustomViewCallback = callback;

                // hide main browser view
                mContentView.setVisibility(View.GONE);

                // Finally show the custom view container.
                mCustomViewContainer.setVisibility(View.VISIBLE);
                mCustomViewContainer.bringToFront();
            }

        });

        webView.loadUrl(url);

        return true;
    }
