I find my issue is related with android version, with android 5.1, the problem exists, but under android 7, it does not exist.

@dsky Your problem seems to be related to hardware, have you tried changing a mobile phone?

After several days of debugging, I found that onMessageFromNatives in cordova.js could not be triggered under the debug version(quasar dev) using quasar 0.16, I have created an issue on github.

@nothingismagick yes, I know that, quasar is great. I just want to know if any other one have same issue with me, or maybe I misunderstood something?

I upgraded to quasar 0.16 from 0.14 recently, my app has a start page, and auto jumps to different pages based on some conditions, in the target page, I just want exit when back button is pressed, but the route is not “#/”.

I found some behaviors were different with quasar v0.14, In 0.16:

1. When using debug version(quasar dev -m cordova -T android), the back button works as expected, but I can not register backbutton event using following code:

  mounted () {
    if (this.$q.platform.is.cordova) {
      document.addEventListener('backbutton', this.onBackButton, false)
    }
    if (this.$store.getters.isFinished()) {
      this.$router.replace('/repo')
    }
  },

onBackButton method never get fired when I pressed the back button.

2. When using release version(quasar build -m cordova -T android), the back button behavior changed, I can not exit app when i am not in ‘#/’ route. seems it’s a new design of quasar 0.15, but why?

And very strange, now the event works, then I can add this code to “fix” the behavior:

    onBackButton: function (e) {
      e.stopPropagation()
      navigator.app.exitApp()
    }

But everything works fine in quasar 0.14. Maybe I misunderstood something?

I have the same issue, my app has a start page, and auto jumps to different pages based on some conditions, in the target page, I just want exit when back button is pressed, but the route is not “#/”, so just not work.

This behavior is only found in the release version. when I do debug build using ‘quasar dev -m cordova -T android’, the back button is working, why?
