You can find the answer to this from the Android Code Style guide.

Follow Field Naming Conventions

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

You'll see it around everywhere. It's the convention. I've always thought of it as myObject, but it really doesn't matter. That's just the convention. Others think of it as "member" object.
