Hello,
I've a GWT application that's used on mobile devices either as a web-app or
installed application with PhoneGap. I noticed that whenever you
use XMLParser.parse("XML stuff") it will use a "significant" amount of
memory and is almost never released fully. I tested this by putting a
taphandler on a button that does nothing but parses a 430 line XML file.
like this:
taskListButton.addTapHandler(new TapHandler() {
@Override
public void onTap(TapEvent event) {
XMLParser.parse("XML FILE as String...");
}
});
When I pressed that button 5-10 times it would increase memory usage by
~1MiB. As my application uses a lot of XML-messages it will increase memory
usage continuously, it might release some after a while when the memory
usage is already high. I don't know what triggers the memory release.
I tested this on Chrome Desktop and I can see on the Debugger Tools
Timeline that document count increases by 1 and DOM node count by ~800 with
each click of the button. With 25mins testing it did clear all of these
from the DOM (at ~2min), but after that they were not cleaned. Can I
somehow manually remove this from memory or trigger cleaning?
