  },
  function (state) {
    props.genActions.geoLocationEnabledChange(state.enabled)
    console.log("backgroundLocationInit. enabled: " + state.enabled)
  }
)

Expected Behavior

App should not reload.

Actual Behavior

If I go to Phone settings and change the app location permission to "dont allow", then when I return to the app it has reloaded. I also see the license key warning

Steps to Reproduce

Context

I want to add functionality to prevent the user from operating the app if background location reports have been prevented eg if user sets location permission to "dont allow".

Debug logs

I have no chrome inspect log as app is in background when I change the permission

in the logcat you can see a "revoked" near the end. This is me changing the app permission setting to "dont allow"

Android app reloads if location permission changed to "dont allow

That’s correct. That’s a fundamental behaviour of any Android application. When permissions change, the app must be restarted into the new permission model.

that has nothing to do with the plug-in.

OK. I have the app location permission aspect working now

But I see that the user can also disable location services at the phone settings level (not app level)

the background process sending locations to our backend url seems to continue despite this. Maybe the location accuracy is degraded because the locations are WIFI based instead of GPS based or something

I have added locationAuthorizationRequest: 'Always', which throws up a modal if the location service is disabled. This helps the user to reconsider her choice. But this is insufficient. I need to detect Location service disabled in the app inorder to disable some app functionality. Is there any support for this in the plugin?

Thanks

See api docs .onProviderChange. I suggest you familiarize yourself with all 13 events available to you.
