How to use MediaSessionCompat?

Question

How do I use a MediaSessionCompat? Can someone give a simple working example?

I've found some, but they use:

MediaSessionCompat _mediaSession = new MediaSessionCompat(context, "tag");

This gives me error: The constructor MediaSessionCompat(Context, String) is undefined and wants me to use MediaSessionCompat(Context, String, ComponentName, PendingIntent)

I found a working example here, which I tested both on kitkat and marshmallow.

But do take note, sometimes, sometimes lock screen control don't appear because of android settings(i.e Settings > Sounds & Notifications > Notification > While Locked > Hide Sensitive Content) See below:
