page lifecycle

Bug Report

Problem

The cordova-android lifecycle clashes with the page lifecycle spec.

What is expected to happen?

There should be some integration between cordova lifecycle and the page lifecycle

What does actually happen?

The cordova even ‘resume’ name clashes with ‘resume’ of page lifecycle

Information

The browser pause event could be a proxy of freeze. currently pause will trigger even on a browser tab change, which makes sense on the mobile webview, but not so much on a browser.

Command or Code

The easiest way to test integration with page lifecycle that I found so far is with chrome://discards/ as stated here https://developers.google.com/web/updates/2018/07/page-lifecycle-api#testing-your-app-in-the-frozen-and-discarded-states

Environment, Platform, Device

Tested with cordova-android and cordova-browser

Version information

Cordova: 9.0

Checklist

• I searched for existing GitHub issues
• I updated all Cordova tooling to most recent version
• I included all the necessary information above

Hello @janpio I got around this by checking the user agent before adding the event listener to filter the desktop browser which works even for the webview build (https://developer.chrome.com/multidevice/user-agent):

if (navigator.userAgent.match(/Android|iPhone|iPad|iPod/i)) {
   document.addEventListener('pause', () => {})
   document.addEventListener('resume', () => {})
}

I realize that the page lifecycle events are not implemented on other browsers and that some applications might depend on current behavior of cordova-browser events so closing this one for now, thanks

[janpio]

The easiest way to find out (and also later to test and verify any implementation in cordova-browser) would be a super simple Cordova app / index.html that outputs the events that are occuring either in the console or in a div on a page.

Could you create one of those and put them on GitHub? (Bonus points if you follow these instructions for a minimal reproduction repository: https://github.com/apache/cordova-contribute/blob/master/create-reproduction.md - because that will minimize the time we contributors have to spend to set this up.)
