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);

Thanks to Marcin for his answer.
I could run the the html files by loading the video. My problem was i was using /MediaBook2 (2)/SampleForVideo.html. But the '/' should be removed when loading from assets. I splitted the string by trimming off the '/' and it worked.
But that was just a sample scenario i was working on to clear my understanding.
I have a much bigger folder structure and now when the .mp4 file is eventually loaded.
The media player is shown but the player is not playing any file.

The file:///android_asset protocol is a WebView-specific thing. That is: other system components can't read those URLs.
The MediaResourceGetter doesn't use the WebView's network stack and therefore doesn't "understand" the file:///android_asset protocol.
In your other question you mentioned you use a local http server - try serving the .mp4 from that.
