Is it possible to find out when Android app returns from background? -

-

so, idea is: user launching application, , have perform task x.

user work time , quit (app in background now).

then open app again (from background) , have perform task x again.

in first case, can use oncreate() of custom application class, not simple second 1 - there's no onresume() method or something. ideas?

accroding activity lifecycle every time activity no more shown user same method called, no matter if went background pressing "home", or overlayed activity.
