Other than saving variable states, what is good practice for onPause, onStop, onDestroy?

I am to the point in the design of my first applicat开发者_StackOverflow中文版ion where I am going to go back through my code and implement the life cycle management. Other than saving state of variables, what are good practices for each of these methods?

For example: clearing animations?

I know the question is sort of vague, but am wondering what your "to-do" list looks like when you are implementing these methods.

Thanks!

• Closing a DB connection.
• Stopping the media player.
• Terminating an active connection, if any

Depends upon the kind of application you are programming.
