Thank you, Marshal. I have integrated HTML 5 before with Android, perhaps, in a very crude or unacceptable method . However, I don't think I did it perfectly or that my intention would have worked at the end of the day.
For example, if one wanted to write a PHP script on the server side for the HTML 5 page(s), say, the login page, could the WebView Class be used to accomplish it? How could that be achieved? Please, I'm not an expert in Android yet. I know certainly that I need some personal development regarding this tech(Android).
