backgroundPermissionRationale property
(Android 11+) Configure the dialog presented to the user when Always location permission is requested.
Just as in iOS 13/14, Android 11 has changed location authorization and no longer offers the [Allow all the time] button on the location authorization dialog. Instead, Android now offers a hook to present a custom dialog to the user where you will explain exactly why you require "Allow all the time" location permission.
This dialog can forward the user directly to your application's Location Permissions screen, where the user must explicity authorize [Allow all the time]. The Background Geolocation SDK will present this dialog, which can be customized with backgroundPermissionRationale.
- Android will offer the Config.backgroundPermissionRationale dialog just once. Once the user presses the
positiveActionon the dialog, it will not be shown again (pressing[Cancel]button does not count). - If the user resets your application's Location Permissions to
[Ask every time], the Config.backgroundPermissionRationale can be shown once again.
Example
BackgroundGeolocation.ready(Config(
locationAuthorizationRequest: 'Always',
backgroundPermissionRationale: PermissionRationale(
title: "Allow {applicationName} to access to this device's location in the background?",
message: "In order to track your activity in the background, please enable {backgroundPermissionOptionLabel} location permission",
positiveAction: "Change to {backgroundPermissionOptionLabel}",
negativeAction: "Cancel"
)
));
