Navigation doesn't stop by removing the NavigationFragment

[mohand1993]

I've noticed that the Navigation continues running in the background even after the NavigationFragment been removed/destroyed. I tried setting the route to null while removing the fragment, but this didn't work as well.

What's the proper way to completely stop the navigation?

Hello

What do you mean by continues runnig in the backgroud? If you want to stop the demonstration, just call .stop() on the instance. If you want to stop the navigation, use the NavigationManager's .stopNavigation()

If none of these would help, please let me know. Thank you

[mohand1993]

The thing is, we are not using the navigation manager directly, i believe it's being used internally in the UI-Kit's NavigationFragment, and since the NavigationFragment is the one starting the navigation, my expectation will be that it stops it as well when no longer needed

[Darxie]

According to this code, the navigation should be stopped once the route is null. We have also tested it and found no problems. Could you please elaborate on what actually happens and what would you like to achieve? Is this happening only with your routing api, or does it happen in this app without changing anything? Thanks

@Darxie I debugged into it and followed the execution path, and yes the line you mentioned is reached and manager.stopNavigation() is being executed, but I keep observing log messages indicating that some service is still running and something keeps being downloaded (see logs below). The issue can also be reproduced using the sample app

Hi, did you read the tutorial on our site? https://www.sygic.com/sk/developers/sygic-maps-sdk/android/getting-started There's a difference between initializing the Sygic engine and the navigation. Firstly, you need to initialize the SygicEngine. Only then you can use it - show a map, use the navigation, download a map. The thing with the UI kit is that the engine seems to be initialized while adding the NavigationFragment - so that everything can work properly. After that, it's not necessary to deinitialize the SDK so I guess that it's not handled by the UI kit. So what you see is not the navigation, but is the engine doing the usual. You can deinitialize the sdk by destroying the SygicContext.

Yes I had a look at the SDK documentation, so i tried now simply initializing the SDK and enabling OnlineMapStreaming without starting any UI Component, the sdk seems to be initialized successfully and nothing happens afterwards (see logs below), but after starting the navigation fragment and ending it, the logs i mentioned earlier starts being logged indicating that some speedcam download operation is running

Hi, Please excuse my late reply.

The offline speedcam database is now downloaded by default, however we plan to make this up to the user in the future.

Thank you for your understanding.

I've used shutdownNavigation() method in onDestroy() method on SygicFragmentSupportV4() fragment for stop the navigation. I hope this will help.
