How do I stop Android Apps from running in background with Samsung Galaxy S3?

Q. Each time i start my cell phone, i have a ton of apps automatically running in the background.
(facebook, camera360, weatherunderground, etc)
I havent even opened these apps up yet, and they are active and running.
I go to each active running app, then hit STOP, but mins later it will start back up.

I made sure all notifications on each app were turned off, but it didnt help any.

Is it normal for all the apps just to keep running like that at startup? I think its draining my battery life. Maybe i should just delete the apps so that i dont have to buy spare batteries.

A. Hold down the home button and swipe away the apps

What would be good Android Apps to use to help a cleaning business be more productive?

Q. I am an RSA for a wireless company, and have a customer adding lines with Galaxy S phones to help her and her employees communicate and be more productive. What would be some good apps to help her?

A. To avoid making multiple calls, you could add a conference calling app. It's always easier to communicate when everyone is on the call, rather then one person that has to relay the message to everyone. You might want to try using http://parlor.fm -- It offers from conference calling for up to 20 users.

I want to start making Android apps whats the best place to start?
