MissingPluginException(No implementation found for method play on channel bz.rxla.flutter/audio)

[TheDumbfounds]

I ran the init method from the example provided, and as soon as I play the sound, I get the error. The play method is taken from the exaple as well. The only thing I replaced was the url to the sound.

[rxlabz]

on an Android or iOS device ?

[TheDumbfounds]

on Android

[rxlabz]

did you runflutter build apk from the example folder ? ( cf. https://flutter.io/platform-plugins/#android-platform-code-javakt )

[TheDumbfounds]

Yes, I did.

[rxlabz]

just to be clear, the default example works, but your code based on it doesn't ?

[TheDumbfounds]

Sorry, I put that wrong. I ran it on my code with the functions of the example project. I will try it out on the example project later, have to go now. I will let you know as soon as I do.

[TheDumbfounds]

Okay, If I use the example as it is, it works fine. But as soon as I delete the main method, and instead instantiate the view at another point, it gives me the errors. Is it necessary that the sound view is the first one to load?

[rxlabz]

Maybe you can try to apply the same "lifecycle" than the example : init the plugin on the initState of the widget which needs to use it ?

[rxlabz]

This issue seems not related to the library code, so I close it for now. Let me know if you can make your own example work.

[TheDumbfounds]

Still can't seem to figure it out... Could you maybe have a look at it? I copied the example's main.dart into soundManager.dart, added a route and navigated to it in the grid.dart file. I still get the same errors.

your java MainActivity seems to be outdated, the Flutter plugin api changed a lot during last month or so. You should start with a new fresh project, or, update your flutter sdk, remove your android and iOS folders and flutter create .

[TheDumbfounds]

Yes, you were right, it was outdated. Starting a fresh project solved the issue. Thank you a lot :)

[TheDumbfounds]

I have one more question. How can I call a sound that is in the same folder as my script calling it (e.g. calling lib\sound.mp3 from lib\main.dart), instead of using an internet url?

[rxlabz]

🤔 hmm... I have no tried this. Maybe you should look at the assets managements docs.
Not related : if this plugin is useful to you, please consider to ⭐️ it ;)

[TheDumbfounds]

I'll for sure give it a star!
I saw that the README.md says you should use the isLocal parameter to play a local file.

I have tried an absolute path:
final result = await audioPlayer.play("C:/Users/User/Desktop/soundy/lib/TestSong.mp3", isLocal: true);

as well as a relative one:
final result = await audioPlayer.play("lib/TestSong.mp3", isLocal: true);

Unfortunately, either an error or no sound :/

[rxlabz]

on mobile, each app has its own directory. Even the simulators work like this. In the example, I download the file in the dedicated app storage directory, and then can play it. But you AFAIK, you can only access to this "programmatically".
(thanks for the star :))

[TheDumbfounds]

Okay, thank you :) No problem 👍

Make a supplement: the location of the play method is important, for example:

play() async {
    int result = await audioPlayer.play('........mp3');
    if (result == 1) {
      // success
      print(1);
    }
  }


build(){
    ...
    // int result = await audioPlayer.play();  // will thorwn a `MissingPluginException` exception.
    return RaisedButton(
         onPressed: play // correct.
     )
}

make a new project and replicate your current app this resolved my issue!

[andzejsw]

The exception is thrown when you're doing hot reload or hot restart. I solved the problem by simply restarting the app

I have tried your latest plugin version 0.8.0 and later but it's give me exception MissingPluginException(No implementation found for method play on channel bz.rxla.flutter/audio)

When i tried with your version 0.7.0 then it's works fine.
can you help me resolve this issue in version 0.8.1 ?
