Android - set Sound Recorder mime type from Intent

Question

I'm using Cordova to build my mobile app and I need to record sounds.
I'm using the media-capture plugin which launches the default android recorder app within this function:

private void captureAudio() {
        Intent intent = new Intent(android.provider.MediaStore.Audio.Media.RECORD_SOUND_ACTION);

        this.cordova.startActivityForResult((CordovaPlugin) this, intent, CAPTURE_AUDIO);
}

The problem is that after I get the file path and try to getAudioVideoData (which contains informations like "duration") the audio recording format (which is default to .amr) seems like cannot be parsed and throws an exception.

private JSONObject getAudioVideoData(String filePath, JSONObject obj, boolean video) throws JSONException {
        MediaPlayer player = new MediaPlayer();
        try {
            player.setDataSource(filePath);
            player.prepare();
            obj.put("duration", player.getDuration() / 1000);
            if (video) {
                obj.put("height", player.getVideoHeight());
                obj.put("width", player.getVideoWidth());
            }
        } catch (IOException e) {
            Log.d(LOG_TAG, "Error: loading video file");
        }
        return obj;
}

I know that the problem is media format because on my older Android device, with 4.4.4, the Sound Recorder app has settings from where I can change file type and if I set it to .wav, than the getAudioVideoData works!

I have tried to add the following inside captureAudio() before startActivityForResult():

intent.putExtra(android.provider.MediaStore.Audio.Media.ENTRY_CONTENT_TYPE, "audio/aac");
intent.putExtra(android.provider.MediaStore.Audio.Media.MIME_TYPE, "audio/aac");
intent.putExtra(android.provider.MediaStore.Audio.Media.CONTENT_TYPE, "audio/aac");

..but with no success.

Answer 1

I couldn't find a way to influence the output of Sound Recorder app via intent, but I solved the main problem, which was that I couldn't read recorded audio file's metadata (duration property).
