"To provide a streamlined experience for short-running foreground services, devices that run Android 12 or higher can delay the display of foreground service notifications by 10 seconds, with a few exceptions. This change gives short-lived tasks a chance to complete before their notifications appear." - Android Docs, if anyone was curious about that weird delay behavior
I think we may be able to improve upon the DefaultLocationClient class by putting all the locationmanager checking methods and also the context extension function into usecase classes that are wrapped by interfaces and the DefaultLocationClient class would depend upon those. That way you could unit test the class better by providing different mock implementations for the interfaces so if you would want to write a test case that checks the output if for example the gps is enabled but the location is not, then that way you could easily do that. It might be overkill but I think every unit test in itself could seem like an overkill. Just my two cents.
Adding foregroundServiceType="location" in Manifest file is very crucial for foreground service to run even if app is closed in higher android version.
Nice video, we have this setup in our app, albeit implemented before the introduction of flows. If you "take requests" for future videos, I would love to see your approach to handling automatic startup of these types of services when a BLE device is present. Our devices requires physical activation and for our app to be ready for this, we have to keep a sticky notification at all times which is ugly. There are workarounds to use "companion devices", but the support for proximity to BLE devices seems limited to the latter two (?) Android versions. It would be interesting to see how you would handle the "do stuff when in proximity"-approach for both newer Android devices as well as for older.
Thanks man, I got really stumped by needing to declare the service type in the manifest. Everything else was flawless and worked but as soon as I closed the app, it would stop sending locations to my server, which frustrated me to no end to the point where I resorted to youtube. Thanks again, this has been very annoying.
hi philip, great video, I was wondering if you had any suggestion for using a default location listener instead of fused location, i need my app to work without play services, thanks
You have the best RUclips channel for Android development for sure. However, I'm old school. I've programmed in a BUNCH of languages... Really a hardware guy though. I cannot wrap my head around Kotlin. Are you not doing any Java tutorials on location services? I honestly, really don't want to learn Kotlin. I don't see it's utility.
awesome! I would like to ask what if I want to share location with my backend and see other users location of my app. is it a good if you request to server every second to update location? How uber taxi app handle it, for example? Thanks
I'd be very interested for Philipp to try to replicate the tutorial a year after it was originally posted. So much has been deprecated and changed in the SDK that it no longer compiles.
Good video, and I'm one of your biggest fans, but unfortunately the user location updates really really slow. Also. Is this a bit too complex? Is there an easier way to do this?
miui kills the foreground service, if battery optimization is enabled and autorun is disabled, I restart the service using FCM, if the device has stopped sending data durin some time, this is not the best solution, but working one
I am working on android kotlin food delivery project i have order tracking screen in which path will be drawn and customer can track the driver’s location application support is 6-12 than what will the best way to do above defined job? I have to send updated lat long to api to suggest me accordingly
I found that calling `stop()` before even attempting to start will cause a problem. The reason I'm sharing this is because I'm trying to implement a `restartLocationTracking()` feature. It's essentially a location tracking refresher that involves calling `stop()` and then `start()`. This feature is particularly important when developing a Hybrid cross-platform app using Ionic and Capacitor. Is there a way to check if the (location is being tracked) before we call `stop()`?
I have tried you other videos also and done each step to replicate the same but still having the issue that the notification is easily removeable by just swiping. With the foreground service i want to show a persistent/static/non-removeable notification which includes the stop button to directly stop the foreground service from the notification. By this the user will not have to open the app and the app will not be running in the background when the user dont want it to. I have tried .setOngoing etc but still not solution. Waiting for you response ..........
Can you make a tutorial on complex survey form using json. Mean to say that the form is dynamically created from server end json response with multiple different layouts like rating bar, editext, radiobutton, spinners
Hello... Am I the only one with the problem that the gps location does not change? So if i try to set a virtual gps location in extended controls, the app will continue to print out the original location until the whole emulated smartphone has been restarted. And then again, only the one location that has been set before the device restart is continuously printed out...
in 4:41 the android studio gives me an error . FusedLocationProviderClient . it gives me red color on these line I don't know how to solve these I did exactly like you .
Hi, another wish I would like to see is background push notifications. I always had problems with that and the implementation is getting harder from experience. Thanks!
Also can I make request a tutorial: would possible to make tutorial about swipetodismiss(compose) but the catch is will wait for the server result before it will dismiss or not?
Sir,, Please help me.. I have faced a problem.. My app previous update version was only 10 megabyte. But now I have added some features,, the size jumped to 25 MB, which is not possible because I have added very small amount of code... When I cancled all and go to previous version by github using version control; it also showing 25MB in released version,,, which was 10MB..
Really really great, what you did. It was exactly what i was searching for ( for nearly a week of search ). Transfer into java was not that complicated. I have one question: why are you building the NorificationChannel inside the Application? I found some others, which are building it inside the Service directly. In that way it seems that they are recreating it with each location update. Cause of this?
I dont think it's possible , for creating UI we need to request through mainactivity and we need to build a channel before our activity gets paused or destroyed , so we need to make use of application class , one other way is to use the Mainactivity and build the channel there
Hello, how can we save this information and send it to the backend? And the second question is how can we send an alarm to the backend when the user turns off the GPS
If for some reason your location doesnt update try with setting HIGH accuracy Priority in request: val request = LocationRequest.Builder(interval) .setPriority(Priority.PRIORITY_HIGH_ACCURACY) .setMinUpdateIntervalMillis(interval) .build() in my case it solved the problem.
It was very informative, but it's not entirely clear where all the code comes from ... I'm beginner in android dev, only know web development and everything is much simpler and clearer there It would be cool if a video appeared on RUclips on how to make a full-fledged gps tracker with sending the received data to the server in MySQL and authorization, or at least there were normal lessons that would teach you how to use the original source to master mobile development...
I have followed all of the process, but the location in the notification bar remains "Location: null" and doesn't update with the actual latitude and longitude. The only difference in my implementation is that I put the call to start the service in the setContent on the MainActivity, just before the NavHost, rather than onClick of a button. This is because I need my app to always track.
@@PhilippLackner Great video BTW, and now I get it, so the phone can get location using the network also besides the the Gps sensor itself, in this case I would rename the variable isNetworkEnabled to isNetworkLocationEnabled. but of course this is a personal preference. thanks a lot for the help
Hey Philipp, thanks for the video and the code. I had problems with foreground service and your code worked perfectly fine. I have an additional question tho. Let's say we want to render a map and a polyline which would render something like a path using the list of locations gathered over time. The map is rendered inside a @Composable. What's the best way to pass the location data from the service into the @Composable, so it can render the path?
did you find a nice way? I am actually trying to find a way to use the location in a Fragment. I need to pass it to something like a StateFlow and collect it in the Fragment.
I've tested with different devices (Samsung S20, Motorola G42 and Pixel 6a), and LocationManager provides a location every 10 minutes in the background. I've not found an approach to reduce this time. However, you must add background location permission in the manifest and request it to the user. Coarse and Fine location will only work in foreground.
Fine and coarse locations will only work in foreground since Android 11. Access_Background_Location is a must BUT these android versions reduce location updates to report them every 10 minutes in my tests with different manufacturers in the background.
@@sedraopamp we had the same results... i thought that this permission will resolve background tracking issues... but still we have empty zone on the map
@@roshkaalex You need also to disable battery optimization e.g. Samsung S20 stops the location manager if that feature is enabled, no matter if background location permission is allowed.
How can I be so lucky I just had a project with background tracking and here it is by best teacher like him on youtube .❤

Hi Philipp. What about ACCESS_BACKGROUND_LOCATION permission? Should we use this permission for tracking in background?
I had to. Also for Android 13 devices you will need to prompt the user to "Allow all the time" for the location permissions of the app.
Fine and coarse locations will only work in foreground since Android 11. Access_Background_Location is a must BUT these android versions reduce location updates to report them every 10 minutes in my tests with different manufacturers in the background.
