onBecameBackground not called

[LeoDroidCoder]

Implemented same as in sample app.
onBecameForeground called
onBecameBackground never called.
At the time of going background listeners becomes empty (due to weak reference) and thus hasn't been called

I just tried this utility and it's giving me the same indication. It really sounded good and was hoping to be able to use it.
