The application crashes and cannot be used again when playing music files that have been deleted

Project Information

  • Repository : Bop - Music Player
  • Title : Bop - Music Player
  • Publisher : Emicla Developers (Sahdeep Singh)

Expected behavior

Supposedly, when I play deleted music files there will be no crashes. And it should, when a user plays a deleted file, a short message will appear like "File not found".

Actual behavior

When I tried playing one of the music in the application, I accidentally deleted the music that I played in the file manager. Then I returned to the album page and played another music. And I see the music files that I have deleted are still available on the Album page. Then I tried clicking the music file that I deleted earlier. Suddenly the application crashes and exits by itself. Then I tried to reopen the application but it couldn't and the crash continued. So I have to restart the application.

How to reproduce

Steps to reproduce the behavior:

  1. Install and open the application
  2. Then go to the album page and play one of the music
  3. Next, enter the file manager page and delete the music you are playing
  4. Then go back to the application and enter the album page again, then you will see the deleted file still exists and is still playing.
  5. Then play another song, and then click on the music file that you deleted earlier.
  6. then the error will be seen

Hi @ahyar92, thanks for making this contribution.

I was able to reproduce the crash following the steps you provided. Although I find it strange that you should delete a song from the file manager while it's still playing.

Your actual behavior should have been described with fewer lines of text. The bulkier the essay, the more difficult it is to keep up. Always keep your texts short and precise when possible.
