Platforms you faced the error (IOS or Android or both?)

Android, as I have no IOS to test

Expected behavior

Recording starts as usual.

Actual behavior

calling _flutterSound.startRecorder with sepcific path resulst in Exception. Calling with null as uri works.

Tested environment (Emulator? Real Device?)

Real Device: Pixel 2. Android Version 10. Build-Number: QP1A. 190711.020

Steps to reproduce the behavior

FlutterSound _flutterSound = FlutterSound();
//some string. example: IfJMfNhpB7NsQmcmbtMc
String widget.audioFileName = "IfJMfNhpB7NsQmcmbtMc"
final String path = await getApplicationDocumentsDirectory();
await _flutterSound.startRecorder('$path/' + widget.audioFileName);
//path for example: /storage/emulated/0/data/user/0/dt.de.voicematching/app_flutter/IfJMfNhpB7NsQmcmbtMc

Additional note

When forcing downgrade in pubspec.yaml to 1.4.7 the mentioned code works.

[hyochan]

Could you compare your code with example project? You need to give specific extensions based on the platform.

[Marco-Bronner]

Can you describe more detailled what for informations you need?
The code in Steps to reproduce should be enough to reproduce this issue with a clean app.

[hyochan]

Check this line in example project.

[Marco-Bronner]

Oh okay. You mean specific file types based on platform. This is new in 1.4.8? Because currently I do not set any.

[hyochan]

Yeah. I should have to update the doc. Maybe you could give a try PRing. Also note that you should specify extension based on the platform.

[heibaikn]

Yeah. I should have to update the doc. Maybe you could give a try PRing. Also note that you should specify extension based on the platform.

before 1.4.8 #Resolve #129
following is my code , and Can run well

      final Directory extDir = await getApplicationDocumentsDirectory();
      final String dirPath = '${extDir.path}/Sound/flutter_sound';
      fileName = timestamp();
      await Directory(dirPath).create(recursive: true);
      final String filePath = '$dirPath/$fileName.mp3';
      print("filePath~~~~~~~~~~~~~"+filePath);
      audioPath = await flutterSound.startRecorder(filePath);

but after 1.4.8 #Resolve #129 , I get a Error

I can fix it by using the default path， but I want save audio file in project path.

  String path = await flutterSound.startRecorder(Platform.isIOS ? 'ios.m4a' : 'android.mp4');

[TharinduNM]

I faced this issue. This only happens for the 1.4.8 version. 1.4.2 version is fine and hence I'm using it at the moment.

[xb284524239]

version 1.4.7 , Can run well .

[jaweii]

This issus wasted my whold day >_<。

[hyochan]

 String path = await flutterSound.startRecorder(Platform.isIOS ? 'ios.m4a' : 'android.mp4');

Have you guys tried this in example project? I am not having problem with it.

[Marco-Bronner]

Hello @hyochan
I do understand the "fix", but what would be the content of the pr? Should I write an update on the documentation or what do you mean exactly?

[hyochan]

@Marco-Bronner PR could be anything if you feel it is needed to other people. I can think of doc support currently. Since I do feel this is resolved, I'll close it.

[tvw]

I guess I found the bug:

https://github.com/dooboolab/flutter_sound/blob/master/android/src/main/java/com/dooboolab/fluttersound/FlutterSoundPlugin.java#L147

path = Environment.getExternalStorageDirectory().getPath() + "/" + path;

Since the path is concatenated with another path providing a path will never work.

Also the example is buggy:

String path = await flutterSound.startRecorder(Platform.isIOS ? 'ios.m4a' : 'android.mp4');

This example works, because it does not pass a path but only a filename. But this is an absolutely useless usecase.

THX , i solve the problem by change author's primary code, it works well now

if (path == null) {
path = AudioModel.DEFAULT_FILE_LOCATION;
}
// else {
// path = Environment.getExternalStorageDirectory().getPath() + "/" + path;
// }

[mattrussell-sonocent]

I'm not sure why the plugin would prepend Environment.getExternalStorageDirectory().getPath() to the provided path, this caught me out today. Could it just...not do that instead?

[MATTYGILO]

Still having this problem has anyone found a good work around to solve the issue.
