How the code works

Once the app is launched, there's a home view with a button in order to navigate to another view. When the button is clicked, a view called MusicPage is loaded. This view overrides this lifecycle methods:

  • ionViewDidLoad: When this event is fired, the view loads a music file in memory
  • ionViewDidEnter: When this event is fired, the music is played in bucle
  • ionViewWillUnload: When this event is fired, the music is stopped.

So, when the view is entered for first time, the audio is loaded. Then it is played, and on pressing back button it is stopped.
