Edit:

This was a bug in Android that was fixed in later versions of Marshmallow

Original:

I believe that this is Marshmallow specific. Are you using a Marshmallow device?

I've noticed this error is printed out every time I switch between applications (doesn't matter which) or exit out of them, and when activities are destroyed.

I've tried running the same apps on two Nexus 5s - one running Lollipop and the other Marshmallow, and these log prints only appeared on the Marshmallow version - with every app, not just the one I'm building.

Not sure why this happens, but I opened a report here.
