cant handle onPause after start the app for second time

i have two countdowntimer, one in onCreate and on in onPuase that they do my jobs every seconds. I tested my app in three ways, the first one has a problem.
1. if start app, press the home key, go to menu and start the app again, my object on the main activity that they will be refresh every second, i mean remove all theme and create all theme every second, will blinking(my problem is this one).
2. if start the app, press the back button key, and from the menu run the app again, every thing is OK.
3. if start the app, press the home button key, recall the app from notifications that app create, again every thing is OK.
