Bound Services on Android

[@cnsnmms3708]

I was working on a ble sensor client service which must communicate consistently with an activity and I was almost hopeless because of the android os restrictions and started service logic. You are solving a very complex issue about android services with a such simple example :) thanks

[@codingwithmitch]

******************** WARNING: BUG ************************ Thanks to @Pemba Tamang for finding this bug. Inside the "run" method of the runnable inside MainActivity, change the "aBoolean" variable to "mViewModel.getIsProgressUpdating().getValue()". If you don't do this then the runnable will continue running forever and spawning new instances. It's due to the "aBoolean" variable being final and then being used to control whether the runnable runs or not. If it's final, it will never change. So obviously the runnable will continue running forever. Here is a gist with the updated run method: gist.github.com/mitchtabian/0621da267a677cabcd1f270e3c6513fa

I love ur tutorial when u explain it very simple to understand for me. Keep it going mitch. I just stuck using bound service in mvvm and u the only reference that I had.

Thank you so much Mitch, that very cool explanation. I request you to please create more content on Services and running task in BG

That will be great if you can make video on startForegroundServices which is must for Android O devices.

Make video on Starting service in ANDROID.O and changes in O. Your explanation is amazing with architectural design.

[@devanshu_on_youtube]

Hey Mitch, love your tutorials! But if I may, isn't viewing a bound/started as service types (though not mutually exclusive) a bit inaccurate as a mental model? What exists is the Service class by itself - it can either be started, be started and bound to or be started as a consequence of being bound to. I think the folks have revised the documentation to reflect this representation as well.

[@nandandesai6524]

How can you run a service in a background thread? Please please make a video on it. Thanks!

[@TheMikkelet]

I do not understand this example, Mitch. I tried downloading the repo and run it. The app doesnt maintain state. There's no notification, like you'd see in a media app, and the app resets the timer if you swipe to close. What is the point of a service exactly? Because it doesn't seem to hold any persistent state

your all videos are awesome. Can you make a complete video/split in series which has all the folder structure.. where to keep UI/ViewModel/Data/DB/Network with MVVM best practice.

[@capitalcouch5095]

Hey Mitch, Great Stuff. Your content has helped me a lot in learning Android. I am starting to do videos on Android as well. I was checking your older videos, a huge improvement in video quality over time. What kind of screen recording software are you using? Thanks :)

[@codingwithmitch]

Hey, it's camtasia.

[@codingwithmitch]

What kind of videos will you be making? Like what topics?

[@capitalcouch5095]

I will start with general beginners Android topics. It seems these get the most views, to get the attraction. Eventually, stuff like building clone apps, or in-depth on a certain topic. You have some recommendation?

[@codingwithmitch]

@@capitalcouch5095 if you are looking to maximize attention then definitely beginner stuff. The unfortunate thing about that is it gets very boring lol

[@capitalcouch5095]

Haha, well no pain no subs gain. Actually, I haven't seen many videos on beginners stuff but digging down in the implementation details inside android framework. What can we expect on this channel for the next year?

[@szymek16s]

Great tutorial, I looking for solution of my problem and it's hard. I have an app which counting work time but when user closed app by accident I want that my time will be still counting cous of the service and whats happend that viewmodel updating view all the time in the same time ForegroundService do the same and my timer shows wrong value.

[@guillermoperez8250]

Cool stuff, thank you. You can get a reference to the service as soon as you bind to it, no need for the observer. Just do: MyService.LocalBinder binder = (MyService.LocalBinder) service; mService = binder.getService();

[@ryszardmachmudow9175]

I read ViewModel should not contain services, because Service has it's own lifecycle. Service field will lead to context leak.

[@nodajifi]

Great leacture about service. In a bound service, I want to implement the never-ending sevice after booting the smartphone. I know that case in a started service but I don't have any clues in the bound one. Could you give me some comments?

[@shawngardner261]

I enjoy your tutorials and classes. Wondering if you could update with foreground services and bringing in more clean architecture like less knowledge in the activity about the service, etc. Thanks!

[@maysal-reem6457]

Great video! And could you please make some videos about the whole services thing because it's confusing

Hi Mitch Please answer this ,i want to make a call waiting app , and i want to post a notification when some one call the phone , I did it using Broad Cast Receiver but i want to do it when app is completely close . is this video what i need ?

[@HydroHeiperGen]

@CodingWithMitch Atfrist, thank you for offering so much of your time to help noobs like me. Your Video is pretty good, but as a experienced Beginner, there are some questions left open. @25.40 As I understood the point of MVVM is to encapsulate the way of getting Data and the displaying of Data, to create a better structured code. So why do we bind the Service to the Activity and pass the ViewModel class instead of starting the Service in the Activity, but bind the service directly to the VM.class? As I understand, in your video, we create a bridge from Service to Activity, which continuous to the VM and the data later on will be send from the VM to the Activity. Can you tell me where I went wrong?

[@codingwithmitch]

This is actually an anti-pattern btw. You shouldn't bind services like this. Check out this article medium.com/androiddevelopers/viewmodels-and-livedata-patterns-antipatterns-21efaef74a54

[@timbraasch1514]

the MVVM pattern sure is a good pattern, but i wouldnt recommend using it in a guide video since it can confuse newer programmers.

[@shyam8999]

[@aminamer5283]

thank you Mitch... another great video! made ma day ?

[@wawa3]

Wouldn't new handler and runnable be created every time the progressUpdating get onChanged this way?

[@IxIAlanIxI]

This was the best tutorial I found on the internet about Bound Services, but the fact that it uses MVVM is driving me crazy, because I can not rewrite my whole project to implement MVVM. Does anyone have a version of this code that does not use MVVM? I watched the video about MVVM to try to "remove" it from the code, but unfortunately I could only get my code to stop working.

[@rizwansayyed7893]

No problem just write service binder instance or create service connection in directly activity meaning remove viewmodel and write service code in mai activity which is in viewmodel

[@aleksamatic9558]

what is your favorite architectural design pattern xD?

[@nishantkumar-fl3cy]

Please make a video on what can we do on background service thread.

[@jacekgawel]

Awesome tutorials.. but It is only for simple Services. What when I have a location service which returns ? I can do all that stuff like "calculate distance" "find speed" "change to LatLng" in service and do some getters methods but I thing it isn't right according to mvvm pattern. So I need to observe data in Repository somehow? There is a simple solution for this? Obviously I can get location from bounded service to activity, like you did, then viewmodel.setvalue(location). From viewmodel send to Repository, do the staff, and observe it, but it isn't right, isn't it?

[@davidfa7430]

Thank you for your great video. I have a question that is it possible to given a service bound by multi-activities? so that no matter which activity is running, the service will keep running without re-create?

[@nktkumar82]

This is awesome.Just had one doubt. Is it not wrong to implement the "Service Connection" inside ViewModel as it is against the concept of MVVM as ViewModel should not contain anything related to Android Framework or android framework apis.

[@devanshu_on_youtube]

That is the ideal case, but I think it's more of a KMM perspective, i.e. if you're targeting multiple platforms like iOS and Android using KMM, it makes sense to encapsulate all business logic in the view-model minus the Android Framework-specific stuff.

Very nice tutorial. But as far as I understand, two separate runnable run at the same time in the activity and in the service to show the progress. It could be better, one runnable runs at the service and inform the progress to the activity via broadcast-broastreceiver or LiveData implementation in connection with viewmodel.
