Problem whem the mobile device goes in to sleep mode

Hi,

im using OnDisable () to clear my games object , my problem is every time the divice goes in to sleep mode it calls the OnDisable (), and whit it the game ends because thats what i have in my OnDisable (). any advice??
is there a Finish() or onDestory() method in Unity??

thx

Maybe you could use OnApplicationQuit or OnApplicationPause
