Instead of passing directly the video URL (following you example), i would have used tokens in the Html file. For example:

<embed src="$VIDEO_URL$" autostart="false" />

where the $VIDEO_URL$ will be the token wich will be replaced during the runtime with a real video URL.

Also, since you cannot change the contents of your asset folder during runtime you should load the html file contents into a String variable and use the replace method to replace the token with a real URL and, finally, pass that string to your webview. Something like this:

//The html variable has the html contents of the file stored in the assets folder
//and real_video_url string variable has the correct video url
html = html.replace("$VIDEO_URL$", real_video_url);
webview.loadData(html, "text/html", "utf-8");
