MonoBehaviour.OnApplicationFocus(bool)

Description

Sent to all game objects when the player gets or loses focus.

OnApplicationFocus can be a co-routine; simply use the yield statement in the function.Implemented this way, it will be evaluated twice during the initial frame: first as an early notification and second time during the normal coroutine update step.

On Android, when the on-screen keyboard is enabled, it will cause OnApplicationFocus( false ) event. Also, if you press "home" at the moment the keyboard is enabled, the OnApplicationFocus() event won't get called, but OnApplicationPause() will be called instead.
