Thank you

> class. This works rather well.
> 2- Event handling: I see your point. Just need to make it non-static and

> 3- The restartInstance was added to avoid breaking the VLC android
> application which still uses a singleton. In the future the VLC android
> application will need to refactored.
> 4- "protected void applyEqualizer()" - This is to allow LibVLC subclassing.
> 5- synchronized was used around nativeInit and nativeDestroy, but I am not
> really sure if it's actually needed. Have to test further as well.
