invoke onDestroy callback twice when rotate the screen

[daselang]

when I have used the FUtils.init(this) in My own Application class witin onCreate(),
and then I rotate the device screen,the activity invoke the lifecycle method as same as before,
and then rebuild a same activity, and the lifcycle method is invoked,onCreate,onViewCreated......onResume.
but unfortunately,the onDestroy is invoked again,and then the activity is finished ,app is stopped.
and then I remove the FUtils.init(this) in application class,everything is fine.
please fix it,thanks.
