5. watch the playlist appear but with 0 Tracks.

Expected behavior

Music Player should open and load valid media files on my sdcard.

Actual behavior

hello,
I cannot get anything to load (into a playlist) or play from my sdcard. This is already an old issue since v5.4.4 of Simple Music Player: SimpleMobileTools/Simple-Music-Player#138 (comment)

But bear with me. What struck me today is that this is not logical since all other Fossify apps have no problem with accessing my sdcard. For example Gallery, Voice Recorder and File Manager.

When I try to open one music file on my sdcard from the Fossify File Manager then Fossify Music Player plays another song instead (the first one of my internal phone storage).
When I try to open a music file on my sdcard from the Fossify File Manager and select VLC there is no issue.
When I try to load any file or folder from sdcard into a playlist, nothing happens it stays stuck at 0 items.

Since my music collection on the sdcard is rather large (~2200 songs / 15GB) i tried adding one small folder ( < 10 ) or single file to a playlist. Nothing from the sdcard is successful.

So what is different between Music Player and the other Fossify apps that it cannot find and open anything from my sdcard?

!! UPDATE !!
So i moved Fossify Voice Recorder output to my sdcard to prove it has no problems with the sdcard.
Low and behold, that showed up in Music Player after i rescanned the media.

So I now started to investigate my sdcard music collection folders more closely.

Findings so far:

1. there was a .nomedia file in the root of my collection. removed that as it could block scanning (?)
2. my original music content is still not seen at any scan, i checked owner / permission and it is the same as newly created files and folders.
3. when I create a new folder on sdcard, 1 or 2 layers deep with freshly copied music Music Player sees it.
4. when I create a new folder on sdcard root and copy some music structure with deep folders (total upto 5 folders deep) it is not seen.

CONCLUSION: Music Player still has some small issues, VLC finds all my sdcard media regardless.

WORKAROUND: I will copy my music freshly over in a shallow structure, something like this seems to work:
sdcard/L1.MyMusic/L2.Artist/L3.Album/files.ogg-mp3

Maybe this can help other users if they encounter the same.

Same issue here.

When I put a song or other music track (mp3 or m4a) in the /sdcard/Music folder, it is not seen by this app. Only when I click 'Rescan media' then (not always !) after a few minutes it is recognized.
Before it is recognized, when I try to play it from another file browser (e.g. FileManager+) and click on 'Open with...' and select Music Player, the MP plays a different track. Weird.

I could understand the 'Rescan media' mandate when the song is in a non-media folder (the app has only access to media files), but it is obvious that an app like yours which does have media access, should be able to read any media file in folders like Music or Videos.

Device: Nothing phone 2a, Android 14.

I can reproduce this on Fairphone 5 / Android 15.

Additional isolation test:

• Internal storage folder with 1 audio file:
  Works. Playlist is created and contains 1 track.

• Internal storage folder without audio files:
  Works. Playlist name dialog appears, empty playlist is created, no error.

• Removable SD card folder with audio files:
  After selecting the folder, a popup appears multiple times:
  "Error: java.lang.IllegalArgumentException: col..."
  Then the playlist name dialog appears, but the created playlist contains 0 files.

This suggests that playlist creation itself works, but resolving tracks from removable SD card folders fails.

Additional findings after further testing:

The SD card itself seems to be indexed correctly by Music Player.

• All audio files stored on the removable SD card are visible under "All tracks".
• I can manually select SD card tracks from "All tracks".
• I can add those tracks to a playlist.
• The resulting playlist contains the selected SD card tracks and they can be played.

This suggests that SD card media discovery via MediaStore is working correctly.

The problem appears to be specific to the "Create new playlist from folder" feature. That feature fails with an IllegalArgumentException popup and creates an empty playlist, while manual playlist creation using the exact same SD card tracks works.

There may also be a second, possibly unrelated issue:

When I manually create a playlist from SD card tracks, playback order does not match the expected audiobook order. The tracks seem to be reordered by some other criterion (possibly title, internal id, or another sort order).

For audiobook usage, the expected order would be track number (and disc number if available).

Additional test results:

I tested an existing playlist.

"Add folder to playlist":

• Selecting an SD card folder shows the same IllegalArgumentException popup.
• No tracks are added.

"Add file to playlist":

• Selecting a single file from the SD card also shows the same IllegalArgumentException popup.
• However, the selected file is actually added to the playlist successfully.

This suggests that the exception is not preventing playlist insertion in general.

For a single file, the playlist entry is created despite the exception.

For folder-based operations ("Create playlist from folder" and "Add folder to playlist"), the same exception seems to interrupt the batch processing, resulting in zero tracks being added.
