React-native-track-player: [Android] Crashing after playback starts

[illestrater]

My users are facing a crash which I cannot replicate myself - here is the crash log

* Also, the line numbers for ExoPlayback.java will not match up with your latest dev, as I've forked w/ my own code to get audio levels. This is so I could display a live average volume level in my app. This is completely unrelated, but below's some of my code if you're interested in adding this as a feature in your package! (Android only at the moment) *

    public String getLevels() {
        if (!initializedLevels) {
            if (player.getAudioComponent().getAudioSessionId() == 0) {
                return null;
            }

            this.visualizer = new Visualizer(player.getAudioComponent().getAudioSessionId());
            this.visualizer.setEnabled(true);
            this.captureSize = visualizer.getCaptureSize();
            initializedLevels = true;
        }

        byte[] fft = new byte[captureSize];
        this.visualizer.getFft(fft);
        String byteData = "";
        for(byte b: fft){
            byteData = byteData + (int) b + ",";
        }

        return byteData;
    }

Will report back soon

[Guichaguri]

That should be it. You must be targeting API 28, right?

[illestrater]

Yep targeting 28.

My users reported that the issue has been fixed and their app isn't crashing anymore after I added the FOREGROUND_SERVICE permission to my own app. Thanks for the commit and your work, again! =]

[Guichaguri]

You did all the work on this one, all props to you! Thanks
