I solved this problem by using Alarm manager. in that i find the recent apps and if our application is in recent app than we are not delete the folder. otherwise we delete the folder every 10 second i check this. — , Oct 12 '15 at 09:40

Place file deletion code inside onDestroy() call back method of your home screen.

I am not using fragment so OnDestory is not possible. – Oct 01 '15 at 10:41
You can use onDestroy on Activity or onStop in fragment and make sure you do it async – Ravi Gadipudi Oct 01 '15 at 10:49

Yes finally i got the Solution of this Question.. For that i used a Alarm Manager service of Android. Alarm Manager Service repeatedly perform the task in android.

So, I call Alarm Manager Service every 10 seconds and i find the recent apps if our application is running than we are not delete the folder. otherwise we delete the folder. Alarm Manager Demo Code

From the above link you can do this. instead of notification code put your code(find recent app and delete the folder if it is not available in recent app.)
