Cordova media plugin can't record audio

Question

So i have a hard time trying to record audio with Cordova Media Plugin My Code :

    var my_media = new Media("toto.3gp",
          ()=>onSuccess(),
          (err)=>onError(err),
          (status)=>mediaStatus(status)
        );
    console.log(my_media); // Media {id: "07053344-6274-09eb-62ca-d63f099f2a4b", src: "toto.3gp", _duration: -1, _position: -1}
    my_media.startRecord();
    console.log(my_media); // Media {id: "07053344-6274-09eb-62ca-d63f099f2a4b", src: "toto.3gp", _duration: -1, _position: -1}

I made sure that the media object is correctly initialized and it is.

on Android console i got this:

Media Permissions are correctly set by the plugin (Automatically):

    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.RECORD_AUDIO" />
    <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />

So what do you think the problem is ?

Answer 1

When cordova-media-plugin starts recording it first creates a file named /storage/emulated/0/tmprecording-.3gp Then it renames that file to whatever name you give it without converting it to any other format, so yeah 3gp is supported, i realised that my issue was due to permissions change from android sdk 23 and above, so sdk 23 introduced runtime permissions. so i just changed androidTargetSdk in my config.xml to 22 and it solved my issue.

Answer 2

The error indicates that it is exactly when the Android MediaRecorder start method is called that the error occurs. I don't think the 3gp extension is supported by cordova-plugin-media. In the plugin I found the following comment in the source code (AudioHandler.java):

* Audio formats supported (tested):
*   .mp3, .wav

But if I remember it correctly I've also managed to record .amr files with that plugin.
