Android. Running a background application does not appear in the task manager.
I have developed a music player with a music processing service. When I launch the music player in the background, I cannot see it in the task manager. How do I make the background app visible in the task manager? Thanks ~
All running services are displayed in the list of running services in applications. I seriously hope you CANNOT hide them.
The icons should not appear in the main application menu. You can remove an icon from this menu without defining the icon / label in the manifest.
Your request sounds sketchy / shady.
Most music player apps put the current notification in the notification bar. You can use it so that when a user taps on a notification, it opens your music player so that he can stop it.
With the new Notification APIs in JellyBean, you can get a notification with buttons on it so they can control it without opening the app.
