In HTML5, how can I keep an Android device’s screen on?

We are developing an App in HTML5 using JQuery.

Is there a way/method, in JavaScript or another technology, to keep the screen "on"?

There is no way to ONLY write javascript or other web code to keep the screen on, without writing at least a little java code.

So your "web code" does not directly run in the application but uses a View as its holder. As you can guess you can't just lock the screen from some code that is not even running in the native part.

I can provide a very easy and simple way to keep the screen on if you are not an expert in android programming. In the first activity, that uses the WebView I guess, add in onCreate after super:
