I followed this tutorial to create an app that displays multiple views, however I discovered that I have a memory leak.

It seems that every time I open the child view, return to the previous view, then open the child view again, the allocated memory will increase critically.
I think this is because the child view has been cached. What is the proper way to avoid memory leaks when creating an app with multiple views?
