This is run every single time an Activity dies (which can be often).  Is that
absolutely necessary?  You already do it once in onDeferredStartup, when Clank
starts up cold, which seems Good Enough™ and better for performance.

I'm not an expert of this...just followed wherever "clearShareImages" is called.
I defer to your judgement. Deleted the line.
