How to Cancel a notification When Android App try Closed By the Swipe?

Once you romantic this new application from the swiping it from inside the recent programs, it can cancel people attributes and you can cancel extremely areas of the fresh new software gracefully. Yet not, if the there are one announcements that were SetOngoing(true), next this type of will remain in case the software abruptly try finalized, there are not one features one to pay attention towards app’s cancellation. What’s the right way to deal with this problem? Has just, I coded a music player, and i developed it in a fashion that on OnStop getting my personal affairs, new alerts is actually canceled (and so is the thread upgrading the fresh new improvements bar within it). After that, OnResume, We trigger the latest alerts again. Once they “previous programs swipe” they out, or mouse click aside, the new notification disappears today, as long as the songs isn’t really to try out. Very to end the newest notification, you must pause they, following swipe aside. If you don’t, there clearly was a leak memory in case your app are closed because of the swipe, the spot where the alerts stays discover and that is buggy later in case the software was reopened, as well as the app injuries for many who click the notice (even in the event maybe that’s because I can not figure out how to rating come with saved state packages). Simultaneously, you will find problematic for people who allow software intimate the latest notice every OnStop, while the this may be would be signed since the member really does other some thing through its mobile phone, although the sounds is actually to play (which type of beats the purpose of they right?) Were there other improved ways to handle it? That a good stored condition bundle if that’s in reality connected to my question? Thanks for the brand new dialogue

No, indeed. This specific service doesn’t get named if software accidents or is terminated from the Os because of thoughts items, and most other causes. This will leave the new alerts, which will result in a myriad of problems with the newest healthy termination of software until it’s force closed by the Os. Many thanks for leaving comments, even though!

I discovered this, finally, shortly after seeking most of the terms conceivable, and you can inspire there is certainly an entire point about. I don’t get it operating yet, but I could report right back which have password as i manage. Here is the service:

Appears you have to implement the fresh new mass media user services once the a beneficial certain style of services you to definitely documents for the notice. I’m in the process of refactoring the center from my password, and this maybe will likely be frightening, but feels a lot more like the very last formula on the a good Rubix’s cube. I can declaration into eg 10 really works circumstances with a few working password (I am hoping).

On 2nd believe, avoid using vГҐr nettside this method. Why would make use of C# for folks who planned to wreck havoc on callbacks? Play with delegates! These are generally best

Okay, therefore, after much dabbling and you can those works instances. I’ve discovered how to handle this dilemma try in order to make good MediaBrowserService with a MediaSession. On the notification manufacturing code, it’s very particular about precisely how you begin that notice (which includes to stay this new Foreground and you may destined to the MediaSession). If this is performed, the fresh new notice will continue to be unlock, even though you intimate the fresh application, and you can clicking it can constantly bring you back into the game destined to the service (comprehend the given password less than). Up coming, you only possess a button to the notification to close off alone additionally the app. Voila, an alerts that does not remain unlock if for example the software was closed on current programs, etcetera.

 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 perform this service after they simply click to pick a file in one of the menu items (so when you look at the a technique named by the a technique entitled by the an enthusiastic OnClick subcontract):

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

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

Ok, now new gamble solution, which is triggered regarding the step gamble intention right here, and helps to make the name to begin with brand new alerts, that’s where StartForeground phone call is done (understand the earliest snippet over the top):

 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 will MediaBroadcastReceiver categories are very simple, thus opinion for folks who actually need you to definitely password. One other situation to notice is you have to join this service membership in order to a task (I would recommend the newest today to try out interest):

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

Generally there, there Was an example of making use of brand new MediaSession and MediaSessionCompat and you can MediaBrowserServiceCompat on the internet someplace. Actually ChatGPT could not look for an example otherwise tell me exactly how to do so. You are welcome, internet. Appreciate your own coding!
