After you intimate this new app by swiping it during the previous programs, it does terminate any features and you can cancel very aspects of this new app gracefully. But not, in the event the discover one notifications that were SetOngoing(true), up coming this type of will remain when your app unexpectedly is closed, and there aren’t people functions one to listen into app’s cancellation. What is the right way to cope with this issue? Recently, I coded a music player, and i developed they in a manner that on OnStop to have my personal items, the notice is canceled (and thus ‘s the bond updating the fresh progress pub within it). Up coming, OnResume, I end up in the newest notice once again. If they “present programs swipe” they aside, otherwise click away, the brand new alerts goes away completely today, provided the music is not to try out. So to finish the latest notification, you have to pause they, immediately after which swipe out. Or even, discover a drip recollections whether your software is actually finalized because of the swipe, where alerts remains unlock and that’s buggy later on whether your app is actually reopened, and the application crashes for individuals who click on the notice (even though perhaps that’s because I can’t learn to get started which have spared state packages). Simultaneously, there was problems for those who allow application romantic the new alerts most of the OnStop, just like the this may be would-be signed while the representative do other something and their mobile, although the audio is to play (which sort of beats the point of they correct?) Have there been most other better ways to handle that it? Who’s a great saved state plan if that’s in reality connected to my matter? Thank you for the latest talk

Of the overriding the latest OnTaskRemoved variety of this service membership, the machine will-call this procedure whenever member shuts the brand new software from the swipe. Each of your own about three outlines password can also be terminate the latest notice which will help prevent this service membership when the software is actually closed of the swipe.

Zero, in reality. This service doesn’t get titled if the application injuries or perhaps is terminated of the Operating system due to memories activities, or other grounds. This may get-off brand new notice, that’ll bring about a myriad of difficulties with brand new match cancellation of application up to it’s force-closed of the Operating-system. Thanks for posting comments, even if!
I found it, eventually, once seeking all of the search terms possible, and you may wow there clearly was a whole area about. I do not have it working yet ,, but I’m able to declaration straight back having code whenever i do. This is actually the solution:
Appears you have got to apply the new news athlete services due to the fact a certain sort of service that registers to your notification. I’m undergoing refactoring the center out-of my password, hence perhaps are going to be scary, however, feels a lot more like the very last formula with the an effective Rubix’s cube. I am able to statement back to including 10 work period with a few functioning password (I hope).
With the 2nd envision, avoid using this procedure. Why would you utilize C# for people who wanted to wreck havoc on callbacks? Use delegates! They have been finest
Ok, very, just after far dabbling and you can all those performs hours. I’ve found how to deal with this dilemma was which will make an excellent MediaBrowserService with a good MediaSession. Regarding notification design code, it is very type of precisely how you start you to definitely notice (with to settle the fresh Foreground and you will bound to new MediaSession). When this is done, the fresh notification will stay unlock, even though you close the fresh software, and you can pressing it will constantly give you back again to the activity destined to this service membership (see the offered code below). Then, you only features a key with the notification to shut by itself and the software. Voila, a notification that will not will still be discover in the event your application try finalized about previous applications, an such like.
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();>. We perform this particular service when they mouse click to pick a file in one of the eating plan situations (therefore inside a technique called because of the a strategy named because of the an OnClick delegate):
if (musicMenu != null) < bool>else < MyMediaPlayer.Play(stillPlayingSameFile);>> GoToNowPlaying(c, mf); public static void InitiateMediaBrowserService(Context c) < //>
Ok, now the fresh play services, that’s triggered on step enjoy intent here, and you will helps make the telephone call first off this new alerts, that is where StartForeground call is done (see the earliest snippet ahead):
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 off if this is the same track if (!IsPlaying() || !stillPlayingSameFile) < player.Start();>>
The fresh MediaButtonReceiver and you can MediaBroadcastReceiver categories are pretty easy, thus opinion for many who absolutely need that code. Others thing to notice is you have to join the service in order to an activity (I would suggest the new now to experience hobby):
protected override void OnStart() < base.OnStart();>
Generally there, now there Was an example of the way you use the fresh new MediaSession and you will MediaSessionCompat and you may MediaBrowserServiceCompat on the web someplace. Also ChatGPT couldn’t see an illustration otherwise let me know exactly how to do this. You are welcome, sites. Appreciate your own programming!
