Not working with Unity 5.4

Hey Kibotu,

This version is not working with Unity 5.4 builds.

I imported your project with latest Unity Classes.jar , on android device while testing(Hit isMusicActive button) its giving below exception.

I tried to debug myself and found that the issue is with the below code in OnAudioFocusChangeListenerService class.

private static FMODAudioDevice getFmodAudioDevice() {

        final UnityPlayer unityPlayer = ManualUnityActivity.unityPlayer;
        if (unityPlayer == null) {
            Log("ManualUnityActivity.unityPlayer == null");
            return null;
        }

        try {
            final Field r = UnityPlayer.class.getDeclaredField("r");
            r.setAccessible(true);
            return (FMODAudioDevice) r.get(ManualUnityActivity.unityPlayer);
        } catch (final NoSuchFieldException e) {
            e.printStackTrace();
        } catch (final IllegalAccessException e) {
            e.printStackTrace();
        }
        return null;
    }

I think since the strucure of the UnityPlayerActivity class has chnaged in new versions of unity, above code is not able to find the varaibel "r" or FModAudioDevice instance.

So i think now we need some different way to get the FModAudioDevice instace. Not sure how.

I am Attaching the latest files from Classes.jar from Unity, for your reference.

@kibotu would appreciate your help.

i assume unity changed the way they use fmod and therefore the workaround for toggling the audio to check if other sound sources are enabled, will naturally no longer work, also i'm not quite sure if it is still necessary. the 'r' was the obfuscated instance of fmod btw, which I accessed via reflection.

Also this is a project done 2 years ago, maybe there is a better way of figuring out if music is being played in the background by now? let me know
