//The behavior you are experiencing is caused by an issue that exists in some Android launchers since API 1. You can find details about the bug as well as possible solutions here: https://code.google.com/p/android/issues/detail?id=2373.
//It's a relatively common issue on Samsung devices as well as other manufacturers that use a custom launcher/skin. I haven't seen the issue occur on a stock Android launcher.
//Basically, the app is not actually restarting completely, but your launch Activity is being started and added to the top of the Activity stack when the app is being resumed by the launcher. You can confirm this is the case by clicking the back button when you resume the app and are shown the launch Activity. You should then be brought to the Activity that you expected to be shown when you resumed the app.
//The workaround I chose to implement to resolve this issue is to check for the Intent.CATEGORY_LAUNCHER category and Intent.ACTION_MAIN action in the intent that starts the initial Activity. If those
