Show HTML5 Video Fullscreen

Question

I have a webview that has html video inside it. I want to show this video fullscreen so I override onShowCustomView of my WebChromeClient to use a VideoView. This works great in 2.3, however, in 4.x onShowCustomView is never called. The video will still play, however, it is played from within the webview without any controls besides clicking for play and stop.

Also, I have hardwareAccelerated="true".

Any idea why onShowCustomView is never called?

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

    setContentView(R.layout.main);

    webView = (WebView) findViewById(R.id.webView);

    webView.getSettings().setSupportZoom(true);
    webView.getSettings().setLoadWithOverviewMode(true);
    webView.getSettings().setUseWideViewPort(true);
    webView.getSettings().setBuiltInZoomControls(true);
    webView.getSettings().setJavaScriptEnabled(true);
    webView.getSettings().setDomStorageEnabled(true);
    webView.getSettings().setPluginState(WebSettings.PluginState.ON);
    webView.setWebViewClient(new WebViewClient());
    webView.setWebChromeClient(new MyChromeClient());

    webView.loadUrl(URL);

}

private class MyChromeClient extends WebChromeClient implements
        OnCompletionListener, OnErrorListener, OnPreparedListener {

    @Override
    public void onShowCustomView(View view, CustomViewCallback callback) {
        Log.d("ma", "onShowCustomView");
    }

...

Answer 1

Well after struggling with this for a while, I finally found the cause. In Android 4.x you must show the controls by using the html 'controls' attribute in the 'video' tag. Once you are showing these controls, you can click on the fullscreen button which will then call 'onShowCustomView'. Since embedded video is available in 4.x and you have the option to go to fullscreen with the controls, onShowCustomView will not be called automatically on play. Unfortunately, this is very poorly documented in the Android documentation.
