Expected Behavior

App should collect and send data to server on regular on the basis of distance filter 100 meter.

Actual Behavior

App is not collecting and sending data while device/user moves from one location to another, this is working fine in example app.

Steps to Reproduce

Context

want to fetch and send location whenever user moves from location with distance filter 100 + with heartbeat also, even in headless mode.

layout: 'notification_layout',

16671): ‼️ Could not find custom notification layout 'notification_layout' in app/src/main/res/layout

If you don't know how to implement a custom notification layout (an advanced config option), don't use a custom layout.

[adn9990]

Working better, But not getting location while travelling. Like in demo app

[christocracy]

The answer to why is written in the plug-in logs. See wiki "Debugging" and learn to observe the plug-in's incredibly verbose logs.

[adn9990]

Can you please tell me, I am not able to understand logs

[christocracy]

Can you please tell me

Go fetch 1-3 days of logs and post them here. tell me what time period(s) you're interested in.

Also see https://dontkillmyapp.com

[adn9990]

Ohk, Let me fetch the logs. I want distance filter 100 if device is in motion and if device is still I want in every 5-20 min this is working fine in example

[christocracy]

and if device is still I want in every 5-20 min. this is working fine in example

That's what BackgroundFetch is for: executing a periodic task, such as calling BackgroundGeolocation.getCurrentPosition().

https://github.com/transistorsoft/flutter_background_fetch

[adn9990]

periodic task is working fine, On issue when device is in motion location updates get stopped
