How do I discover memory usage of my application in Android?

Question

How can I find the memory used on my Android application, programmatically?

I hope there is a way to do it. Plus, how do I get the free memory of the phone too?

Hackbod's is one of the best answers on Stack Overflow. It throws light on a very obscure subject. It helped me a lot.
