Describe the bug

I need to download a remote audio file for editing. I'm using ffmpeg to cut and modify this audio and then I'm using FlutterSound to play the results.

The problme is that a PlatformException exception is thrown when I try to play the local .mp3 file that I downloaded. This exception only happens on a real device and not the emulator.

I was thinking that it could've been that I have two active players in the application but after changing to code to use only one the problem is still present. Remote audio files play just fine, the problem only appears when trying to play the file that I download. Once the problem appears the player fails to play remote or local files.

I'm using the following lines to play my audio files:

Future play(String filePath) {
  player.setSubscriptionDuration(_subscriptionHandler);
  return player.startPlayer(fromURI: filePath);
}

To Reproduce Steps to reproduce the behavior:

please allow give me a little bit of time to create a sample project that can reproduce this error.

I'm have this error too :/

[db-rdz]

I found what the problem was in my case but I haven’t found a good fix just a work around.

At least in my case the problem was with the initialization of the recorder and player. Opening the player before I open the recorder helped in my case but this is a work around instead of a fix and the error message is too general so it might be a total different thing for you

[VeerneToor]

I found my problem too :D, mi problem start with a directory of application, the app directory by a anonymous reason don't allowed write, I used the temporal directory for solve this problem

The problem is that a PlatformException exception is thrown when I try to play the local .mp3 file that I downloaded. This exception only happens on a real device and not the emulator.

Maybe you can look to #710 There is a problem with Flutter FFmpeg :

You must also check your build.gradle :

Remove any reference to repository jcenter() Add a reference to mavenCentral() if not already done

How to play the local audio of the project. It's like using local pictures ？？

I'm also having the problem with a real Android device. The logs are not helpful and I don't know what to do... Has anyone found the solution?

I was facing same issue with same package audioplayers. For android specific we need to configure path to access local media files from our devices.

For these I have used following dependencies:

1. file_picker : <latest-version> (For picking file path)
2. audioplayers: <latest-version> (For playing audio files)

To set custom path for getting local media file you need to put following code in your file:

pickSong() async {
    FilePickerResult? song = await FilePicker.platform.pickFiles(
      type: FileType.audio,
    );
    if (song != null) {
      var temp = song.files[0];
      songUrl = "file://${temp.path}";
      songName = songUrl.split("/").last;
      await player.setSourceUrl(songUrl);
      print(songUrl);
      duration = await player.getDuration();
      setState(() {});
    }
  }

The path for local media would look like : file:///data/user/0/com.example.ble_audioplayer/cache/file_picker/song_name.mp3
