Bound Services on Android

With respect to Services on Android, you have two categories:
1) Started Services
2) and Bound Services
This video is focused on bound services.
I think the best way to think of a bound service is to compare it with a server. When you start a service with the intention to bind something to it, you essentially have the intention to start a server, and bind to it with some kind of client. At it's core, you're defining a client-server interaction. The service acts as the server, and an activity acts as the client.
Note that this demo is done using the architectural design pattern known as "Model View View-Model" (MVVM).

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

@devanshu_on_youtube Жыл бұрын

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.

@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 5 жыл бұрын

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

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 Жыл бұрын

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.

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.

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();

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?

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

******************** 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

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.
