Android audio player activity -

i have music player app created, while im playing music , exit app pressing home or button , launch app again, doesn't return current state exit app , song index goes default value 1 music still playing. , when play music again, current song played still playing. therefore, there 2 songs playing. how can save current state of application?

you can save states in onpause() , can retrieve them in onresume()

or can use onwindowfocuschanged() :

public void onwindowfocuschanged(boolean hasfocus) {      super.onwindowfocuschanged(hasfocus);     if(hasfocus)          //retrive state     else         //save state }
