MAUI Android Background Services: The .NET Show with Carl Franklin Ep. 46

[@jitendrajadav9110]

Thank you @Carl Franklin, please add background services for iOS this will really help!

[@DeveloperExpress]

He's working on it.

@@DeveloperExpress Thank you so much really appreciate!

[@benhorton6758]

Hi @@DeveloperExpress, any update on an iOS version? It'd be really helpful

[@Spud9]

​@@DeveloperExpressIs there any progress on this? There's no really helpful guidance I can find anywhere else.

[@kelputoo.]

It works, however an annoying notification will always appear sticky on your phone, is there any way to make a REAL background service and not a foreground service? I want to be able to display notifications on the app, without a foreground notification service. The title isn't very good explicit.

[@cissemy]

Can you make one about IOS ? Thanks

[@jonny.rubber]

Amazing tutorial. Just implemented SignalR to show an Alert in my MAUI app, but was thinking of exactly this functionality. After a quick browse I came here. Everything is there. Not as simple as I imagined it. Hopefully I'll find the same for Windows and iOS. Thanks a lot.

[@carlfranklin7894]

Not at all as simple for iOS. I'm still trying to figure that out.

[@billymartin6497]

Great video. Would really love to see one on Home Screen Widgets, something a lot of us would love to do.

[@ShinkuRaj-ji8nc]

Hi Thanks for sharing the video. I have a small Doubt Can we have implement Dependency Injection to this Backgroud Service

[@Dimitris.Christoforidis]

Thank you Carl!! Exellent work!! Background jobs are very important in mobile apps. I wonder if there is any ready-made library for this purpose. I looked for shiny-jobs. I don't think that it works very well. Do you have found any other libraries for net maui?

[@carlfranklin7894]

No, I couldn't find any. That's why I wrote it myself. :)

[@Dimitris.Christoforidis]

​@@carlfranklin7894 Thank you Carl! Can you create a ready library for this? Like a nuget? Or to add it via devexpress maui libraries in future.

[@Spud9]

@DeveloperExpress, I'm running into an issue where after the app's closed and I get a notification, if I click the notification the app tries to launch but then gets stuck and crashes. Any insights?

[@danielbrown7534]

did you find a solution I am having the same issue.

[@michaelhamilton6905]

It would be nice to have some more details in regards to the warnings about not using it in production due to security concerns. It is not clear to me what are the details about the security concern or what needs to be done to mitigate that concern.

[@marcoerlwein2165]

great Carl, thanks a lot, please for IOs

[@carlfranklin7894]

Working on it. iOS has an official process for notifications, so I'm first going to focus on background services, which have to continuously restart themselves to avoid being shut down by the OS.

This is an excellent video, thank you! Does it work on Android Emulator (Pixel 5 API34 Android 14)? I got it to work on my phone but not the emulator.

Can the same done for Windows?

[@marcoerlwein2165]

Carl, one question, hubConnections work with SignalR on iOS?

[@carlfranklin7894]

I don't see why not, although iOS is a completely different beast when it comes to notifications. If your goal is to show notifications, there's a completely different process you need to go through. If you just want some kind of background service, as I showed in Android, it's possible, but you have to jump through hoops to make sure iOS doesn't shut you down. I'm struggling with the process, but I'll do a show on it when I get some answers.

[@marcoerlwein2165]

@@carlfranklin7894 Hi Carl, when is the video for IOs? sorry for the pressure, but there is not much information for IOS.

[@hamzaougui6751]

Amazing tutorial thank you so much .. can please the same tutorial for Maui Blazor IOS ? .. waiting for it please

[@lukasjacobs2358]

Would have been nice if there actually was something about a background service. I'm aware of the distinction and was actually looking for background service information, not foreground...

[@iamzoli]

you can extend the foreground service by implementing Android.Content.BroadcastReceiver that receives SCREEN_OFF event and when it does acquire Android.OS.PowerManager.WakeLock with WakeLockFlags.Partial. then it will run all the time.

[@kelputoo.]

Same, did you found any way to do it?

[@bruno-id1wh]

This video is exactly what I need for my project, but unfortunately I can't get the boot receiver working - it throws a Permission Denial exception at startup. I thought I must have missed something but it does the same running the code from github. Any ideas please?
