Question

What can cause the live activity to not be displayed?

ahmdaeyz opened this issue 2 years ago · 33 comments

Hey!
Thanks for the great work!
I've tried the example app and it works fine. I also tried to go through the steps on a new project and it worked. But when I try to go through the steps in an existing project. The activity doesn't show up. The activity id gets created normally and If I hooked the creation function call to a button and pressed multiple times I get that the maximum number of activities is reached (as an error).

So is there a unique reason to this?

I've some background modes enabled like remote notification and background fetch. I'm also using Firebase Messaging. Notifications permissions are all setup.

Thank you.

Answer 1 · 2023-02-25T15:34:29.000Z

could be a lot of things.

Did you name your attributes LiveActivitiesAppAttributes and have a typealias LiveDeliveryData?
Did you add an app group?
does your Info.plist have "Supports Live Activities" to YES
are you testing on a real device? Does that device support live activities?
It sounds like the createActivity function is being called and ID is being generated so it's probably something to do with the Swift code. Maybe provide some snippets of your widget?

Answer 2 · 2023-02-25T17:47:57.000Z

I have gone through your checklist on other issues so yes I have done all that.

I'm using a real device and it supports live activities.

I am using the generated example which displays a hello world text in cyan background. And as I mentioned it's working on a dummy project.

Answer 3 · 2023-02-26T14:47:47.000Z

@ahmdaeyz did you get an activity id after createActivity ?

Answer 4 · 2023-02-26T14:59:16.000Z

@phuchuynhStrong Yes I did get it.

Answer 5 · 2023-02-26T15:08:37.000Z

@ahmdaeyz To be clear, are you talking about live activities on dynamic island or lock screen ?

Answer 6 · 2023-02-26T15:19:43.000Z

@phuchuynhStrong Both of them. I'm interested in both. I don't have a 14 pro myself but I have tested the example on the simulator and it was actually working.

Answer 7 · 2023-02-26T15:24:59.000Z

@ahmdaeyz can you show the code of ActivityConfiguration ? The place where you did the Ui of dynamic island and lock screen

Answer 8 · 2023-02-27T15:44:13.000Z

Have you tried on a real device? What version of iOS? Needs to be at least 16.1

Answer 9 · 2023-02-27T17:24:57.000Z

@jolamar
Yes I'm testing on a real device.
The version is 16.3.1
I have set the app group for both the widget and my runner
Here's my widget extension in xcode

@phuchuynhStrong
Here is my code using the ActivitiyConfiguration

Here is the bundle:

Answer 10 · 2023-02-27T20:58:09.000Z

might be good to wrap the WidgetBundle like so:

    if #available(iOS 16.1, *) {
      WatchlistPriceUpdatesLiveActivity()
    }

other than that the widgetconfiguration looks good. Flutter side did you init with appGroupId?

      _liveActivitiesPlugin = LiveActivities();
      _liveActivitiesPlugin.init(appGroupId: "[YOUR APP GROUP]");

Answer 11 · 2023-02-28T08:53:01.000Z

Okay I will add that.
Yes. I initialize the plug-in and then create the activity. And to make sure the problem isn't related to initiation I created a button to create the activity. Still no exceptions. And the id is returned. But no UI on the Lock Screen. Or any sign of a live activity whatsoever.

Answer 12 · 2023-03-01T02:40:57.000Z

@ahmdaeyz your code looks fine. Can you make sure Live Activity is enabled in app setting ? (Go to your phone setting -> your app)

Answer 13 · 2023-03-05T20:38:14.000Z

@phuchuynhStrong It is indeed enabled. I check several times after creating an activity. Can there be some kind of conflict causing the activity not to be shown?

Answer 14 · 2023-03-06T08:28:51.000Z

Do you have added the entry in the info.plist file ?

Answer 15 · 2023-03-06T11:26:43.000Z

@istornz Yes I have added it both to the widget extension and my Runner's info.plist. If I haven't I think an exception will be thrown.

Answer 16 · 2023-03-06T13:40:15.000Z

@ahmdaeyz I can't think of any other reason, why it's not working. Make sure you're testing on an iPhone

Answer 17 · 2023-03-06T14:40:41.000Z

@phuchuynhStrong Not sure if you are being sarcastic. But be assured I've been testing on an iPhone all along :).

Answer 18 · 2023-03-06T15:08:21.000Z

@ahmdaeyz no. I made a mistake by testing the live activities on iPad so I just give you another clue to identify your problem

Answer 19 · 2023-03-09T10:57:41.000Z

@istornz @phuchuynhStrong @jolamar Do you guys have any advice on how I can debug the problem?

Answer 20 · 2023-03-09T17:31:08.000Z

@ahmdaeyz I'd break down the problem and see where it's failing. So take away all the variables you can and start adding them back. So I'd start with removing Flutter aspect of it and just try adding any native live activity to your project. Can follow some of these instructions https://ohdarling88.medium.com/update-dynamic-island-and-live-activity-with-push-notification-38779803c145 if this fails then you know this plugin isn't the problem and there is something in your project that needs addressed.

Answer 21 · 2023-03-21T15:15:00.000Z

Hello @ahmdaeyz, did you find the problem?

Answer 22 · 2023-08-01T00:02:04.000Z

@ahmdaeyz having the same issue, everything enabled..

also enabled remote notification

other extension that i have is one signal extension, which is interesting since you also have a notification extension

testing on a new project working fine, but not working on existing projects

Answer 23 · 2023-08-01T09:17:15.000Z

@ahmdaeyz @istornz @jolamar

I found a solution, if you have it checked, uncheck "Copy Only When Installing" for Embed App Extension or similar on build phase of main target runner.

Prob need to add that to the readme

Answer 24 · 2023-08-03T19:56:00.000Z

Does anyone have any solution?
I have check what @Arepeel said, but mine wasn't not even checked. So, still looking for some help here
@ahmdaeyz any solution?

Answer 25 · 2023-08-16T17:22:30.000Z

I have found the problem.
The problem was the use of images, when I integrate on my project, I've used another images to shown, but they had high resolution compared to the example ones.

Using the resizeRefactor property fix the issue
e.g: teamALogo: LiveActivityImageFromAsset('assets/images/psg.png', resizeFactor: 0.3),

Answer 26 · 2023-11-03T15:01:12.000Z

@ahmdaeyz @istornz @jolamar

I also encountered this problem, and as far as I understand, this problem does not depend on specific factors in the iOS module, because I tried the following options: I added live activity to my project, to a newly created (clean) project, and also in a project that attached to the example, I deleted the target that was created and tried creating my own new one - my own new one doesn't work.

The steps were carefully followed to those described in the README.md file. (Also, as far as I understand, this is not a problem of this plugin, since this problem also occurs when we do not use this plugin, but try to integrate from live activity directly into AppDelegate)

hi, I was using version 1.7.5, and that version worked well, but when I updated it to 1.9.0, it doesn't work. I don't know why yet
1.9.0 Is there no problem?

Answer 28 · 2023-11-12T13:23:38.000Z

hi, I was using version 1.7.5, and that version worked well, but when I updated it to 1.9.0, it doesn't work. I don't know why yet 1.9.0 Is there no problem?

1.8.0 worked well.
Test results indicate that a new installation should not be made in the simulator
My guess is that 1.9.0 is problematic

Answer 29 · 2023-11-12T17:07:18.000Z

Hi @soulwawa, could you try to implement multiple notification key system like said on the doc? https://github.com/istornz/flutter_live_activities/tree/main#multiple-notifications-

This is just to test if this is the problem or not 👍

Answer 30 · 2023-11-14T10:31:30.000Z

@istornz It works well if you follow your guide.
I'm worried that there are people who make the same mistake as me.

Thank you for your kind reply.

Answer 31 · 2023-11-14T11:15:15.000Z

@soulwawa Thanks for your reply, I will add breaking change in the README.md & CHANGELOG.md file.

This fix was intented to allow multiple notification to work 👍

Answer 32 · 2024-01-25T07:06:34.000Z

For clarification and anybody who debugged as long as we did without success:

While migrating to the new version, we forgot to read the instructions carefully.
In our case following code (mentioned in the Readme) did it:

extension LiveActivitiesAppAttributes {
  func prefixedKey(_ key: String) -> String {
    return "\(id)_\(key)"
  }
}

This is used to extract the params:

ActivityConfiguration(for: LiveActivitiesAppAttributes.self) { context in
      // create your live activity widget extension here
      // to access Flutter properties:
      let myVariableFromFlutter = sharedDefault.string(forKey: context.attributes.prefixedKey("myVariableFromFlutter"))!

      // [...]
}

We did not get it, because there is no error if parsing the arguments fails. Therefore, we got an ID after calling createActivity() on flutter side.

Answer 33 · 2024-02-15T17:05:01.000Z

I was dealing with this issue as well. I found in some cases all you need to do is turn your device all the way off and turn it back on.
