altShiftDev commented on CB-14144:
----------------------------------
[~jcesarmobile] this isn't some kind of conspiracy where I know quasar is the
issue and I'm trying to mislead you...
My troubleshooting of quasar found it was not the culprit, the line in question
is the only "addEventListener" for backbutton in the entire framework and it
doesn't fire before the app closes, see for yourself by commenting out the line:
node_modules > quasar-framework > dist > quasar.mat.esm.js (line 310)
The reason I believe it's a cordova issue is that the event when that
navigator.app.exitApp is commented out the backbutton still kills the app, but
only on API 23 and below.
> BackButton Event Listeners do not fire on Android API 23 or below

> Key: CB-14144
> URL: https://issues.apache.org/jira/browse/CB-14144
> Project: Apache Cordova
> Issue Type: Bug
> Components: cordova-android
> Affects Versions: cordova-android-7.0.0
> Environment: Using Android Studio emulators Galaxy, Pixel, Nexus 5...
> all exhibit this behaviour.
> Quasar Framework is building my project a long with webpack but I've no
> reason to suspect Quasar as the cause, they only register a single
> eventListener for backbutton and I've manually gone in and edited the source
> code for this listener and it never fires leading me to believe the problem
> is with Cordova.
> Reporter: altShiftDev
> Assignee: Joe Bowser
> Priority: Major
>
> App exits immediately on back button press without ever firing the
> eventListener designed to capture and reroute it.
> There is nothing wrong with my eventListener code, it's been tested on Api 25
> and higher and is very stable:
> `document.addEventListener('backbutton', this.onBackButton, false)`
> I have not yet tested to confirm if API 24 has this bug or not.
> This affects many of my users, including myself as I've got a phone running
> Android at these versions. The app is completely killed with every tap of the
> back button (new launches of the app cold boot with splashscreen) making it
> impossible to properly navigate the app: closing modals, moving backwards in
> operations, etc...
