Android programming m before objects [duplicate]

Question

I am new in Android programming, and I saw there is a "m" before objects, like:

mCursor

mAdpter

mView

---

So what is this "m"? Should I use it in my code?

Sorry for this poor question...

Answer 1

Follow Field Naming Conventions

1. Non-public, non-static field names start with m.
2. Static field names start with s.
3. Other fields start with a lower case letter.
4. Public static final fields (constants) are ALL_CAPS_WITH_UNDERSCORES.

You can see the document on those rules here.
