MediaSessionCompat NullPointerException only on Android 8

fellow community!

So I have a problem in my application, that is using MediaSessionCompat.

The problem which is a crash occurs only on Android 8 version (8.1 too), but mostly on 8.0.0 on different devices.

Fatal Exception: java.lang.NullPointerException Attempt to invoke virtual method 'java.lang.Object java.lang.ref.Reference.get()' on a null object reference

I've searched through Google's Forums, where this problem was reported previously and through StackOverflow and hadn't succeeded.

Can someone give some tips or advices?

The problem was solved by updating to the latest support library version.

The answer was found somewhere deep in the bug-tracking forums of Google.

If someone will struggle with the same problem - try to update your support library version at least to the 27+ version.
