When you romantic brand new application from the swiping they in the previous applications, it does cancel any qualities and you can terminate most regions of the fresh new app gracefully. not, in the event the there are one announcements which were SetOngoing(true), then such will continue to be in case the app quickly is actually closed, there aren’t one functions one pay attention with the app’s cancellation. What’s the right way to manage this dilemma? Has just, We coded a music player, and i also install it in a fashion that about OnStop for my factors, this new notification was canceled (thereby ’s the thread updating the latest progress bar within it). Upcoming, OnResume, I bring about new alerts once again. If they „previous software swipe“ they aside, or simply click away, brand new notice goes away today, provided the music actually to play. Very to end the notice, you must stop it, then swipe aside. If not, there’s a leak memories when your application is actually finalized because of the swipe, the spot where the notification remains discover which can be buggy after when your application is actually reopened, together with software injuries if you click the notice (though perhaps that is because I can’t learn how to get started having stored state packages). Additionally, you will find an issue for many who allow software romantic the brand new notice most of the OnStop, since this may be could well be finalized as the member really does other some thing through its mobile, as the audio is actually to tackle (which type away from defeats the point of they right?) Were there almost every other better and improved ways to handle this? Who’s an effective spared state plan if that’s actually strongly related to my point? Many thanks for the new discussion

Just how to Terminate an alerts When Android os App is actually Finalized From the Swipe?

Of the overriding new OnTaskRemoved variety of this service membership, the system will call this process whenever member closes the latest app because of the swipe. Each of your three traces code is cancel the fresh notification and give a wide berth to this service membership if the software are finalized by swipe.

No, indeed. This specific service does not get named in the event that application accidents or is terminated from the Operating system because of memory circumstances, and most other grounds. This will get off the brand new notice, which will end in all kinds of problems with the newest fit cancellation of software up to it’s force closed from the Operating system. Thanks for leaving comments, regardless of if!

I found that it, in the end, immediately after looking to all the key terms imaginable, and you can inspire there is a complete part about. Really don’t have it performing yet, however, I’m able to report right back which have password while i perform. This is the solution:

Looks you have got to implement the newest mass media member service just like the a specific form of provider that information on the notification. I’m in the process of refactoring the heart off my personal code, and therefore perhaps is going to be terrifying, however, feels similar to the past formula on an effective Rubix’s cube. I will declaration back in for example 10 really works period with many performing password (I am hoping).

On the 2nd consider, don’t use this method. Why should you utilize C# if you wanted to wreck havoc on callbacks? Play with delegates! These are generally finest

Okay, thus, after much dabbling and you may all those work circumstances. I’ve discovered the best way to deal with this dilemma is actually to manufacture a great MediaBrowserService that have an excellent MediaSession. On the notice development password, it is extremely sorts of about how you start you to notice (which has to stay the Foreground and you can destined to brand new MediaSession). If this is performed, the alerts will continue to be discover, even although you romantic brand new software, and you may pressing it will always bring you back to the activity bound to this service membership (see the offered password lower than). Next, you just has an option with the notification to close alone therefore the application. Voila, an alerts that will not will still be open when your application is actually finalized about recent programs, etc.

 public static void CancelNotificationBreadCrumb() < if>> public static void NotificationNowPlayingBreadCrumb() < try>); manager.CreateNotificationChannel(notificationChannel); Notification notification = NowPlayingAdapter.InflateNotification(context, currentFile, ChannelId, pendingIntent); service.StartForeground(MY_MEDIA_NOTIFICATION_ID, notification); manager.Notify(MY_MEDIA_NOTIFICATION_ID, notification); // Then trigger the thread to update the real-time features if (cts == null || cts.IsCancellationRequested) cts = new CancellationTokenSource(); ThreadPool.QueueUserWorkItem(new WaitCallback(RunInBackground), cts.Token); > catch(Exception e) < string>> public static void CloseEntireApp()

public class MyMediaPlayer : MediaBrowserServiceCompat < private>public const string ActionPlay = "com.xamarin.action.PLAY"; public const string ActionPause = "com.xamarin.action.PAUSE"; public const string ActionNext = "com.xamarin.action.NEXT"; public const string ActionStop = "com.xamarin.action.STOP"; public const string ActionBack = "com.xamarin.action.BACK"; public const string ActionCloseApp = "com.xamarin.action.CLOSEAPP"; public static string ChannelId = "NowPlayingNote"; public static string MY_MEDIA_ROOT_ID = "media_root_id"; public static int MY_MEDIA_NOTIFICATION_ID = 1111111; public static string MY_MEDIA_TAG = "media_tag"; public override void OnCreate() < base.OnCreate();>. 

I create this service after they simply click to choose a file within the diet plan issues (so in the a technique entitled of the a strategy titled from the an OnClick delegate):

if (musicMenu != null) < bool>else < MyMediaPlayer.Play(stillPlayingSameFile);>> GoToNowPlaying(c, mf); 

 public static void InitiateMediaBrowserService(Context c) < //>

Okay, so now the fresh new play provider, which is triggered in the step enjoy intention here, and you may helps to make the telephone call to begin with this new notification, that’s the spot where the StartForeground phone call is generated (understand the basic snippet above):

 public static void Play(bool stillPlayingSameFile) < //>// Finally, add this file to the list of those recently played int indexToPlay = allFilesInCurrentContext.IndexOf(currentFile); if (indexToPlay >= 0) recentIndexes.Add(indexToPlay); if (recentIndexes.Count > maxRecentIndexes) recentIndexes.RemoveAt(0); > // Finally start the player, which picks up where left Ећimdi Еџuna bak. off if this is the same track if (!IsPlaying() || !stillPlayingSameFile) < player.Start();>> 

This new MediaButtonReceiver and you may MediaBroadcastReceiver classes are pretty simple, very remark if you want you to definitely code. Others point to remember is that you have to join the service so you’re able to a task (I recommend the fresh today to relax and play activity):

 protected override void OnStart() < base.OnStart();>

Generally there, there Is actually an example of how to use brand new MediaSession and you can MediaSessionCompat and you may MediaBrowserServiceCompat on the web somewhere. Even ChatGPT cannot look for an example or let me know exactly how to take action. You are anticipate, internet sites. Delight in the programming!
