App is resuming form a On-click method When I Exit and Reopen It?Android -

i have done 3 pages activity in

1. splashscreen
2. mainactivity
3. results

so here passing value server mainactivity url query string results page on there display results.

i passing this

mainactivity :

@override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.maina);          toolbar toolbar = (toolbar) findviewbyid(r.id.toolbar2);         setsupportactionbar(toolbar);          final button click = (button) findviewbyid(r.id.sc);         click.setonclicklistener(new view.onclicklistener() {             public void onclick(view v) {                 mainactivity.this.finish();                 //mainactivity.this.finishandremovetask();                 intent la = new intent(mainactivity.this, results.class);                 la.setflags(intent.flag_activity_reorder_to_front);                 la.setflags(intent.flag_activity_new_task);                 la.setflags(intent.flag_activity_clear_task);                 la.setflags(intent.flag_activity_no_animation);                 startactivity(la);             }         }); } 

so display value results. on there have added handler results after 9000ms again mainactivity

results :

new android.os.handler().postdelayed(new runnable() {     @override     public void run() {         results.this.finish();          intent v = new intent(results.this, splashscreen.class);         v.setflags(intent.flag_activity_reorder_to_front);         v.setflags(intent.flag_activity_new_task);         v.setflags(intent.flag_activity_clear_task);         v.setflags(intent.flag_activity_no_animation);         startactivity(v);     } }, 9000); 

and @ part of main activity have added alert on back-pressed yes/no option exit entire app

mainactivity :

  @override     public void onbackpressed() {          alertdialog.builder alertdialogbuilder = new alertdialog.builder(this);         alertdialogbuilder.settitle("do want exit app!");         alertdialogbuilder                 .setmessage("click yes exit!")                 .setcancelable(false)                 .setpositivebutton("yes",                         new dialoginterface.onclicklistener() {                             public void onclick(dialoginterface dialog, int id) {                                 movetasktoback(true);                                 mainactivity.this.finish();                                 android.os.process.killprocess(android.os.process.mypid());                                 system.exit(0);                             }                         })                  .setnegativebutton("no", new dialoginterface.onclicklistener() {                     public void onclick(dialoginterface dialog, int id) {                          dialog.cancel();                     }                 });         alertdialog alertdialog = alertdialogbuilder.create();         alertdialog.show();     } 

here it's exiting app when re-open application it's starting results page moving results splashscreen in handler.

here have removed in mainactivity

/* @override protected void onresume() {     super.onresume(); }*/ 

but it's starting results page. can suggest how exit app or how stop resume results page?

update

here problem exit...i giving exit option on pressed

so have 2 scenarios

scenario 1

when launch app start splashscreen --> mainactivity. here exiting app @ mainactivity - it's exiting fine. here exit working fine.

when re-open app after exit, start splashscreen --> mainactivity

scenario 2

it starts same first in mainactivity have button. when click on button, pass url query string intent start results page after 9000ms again go splashscreen --> mainactivity

so here exiting app @ mainactivity

but when re-open app after exit, start results page form , doing handler , again going splashscreen

can suggest missing have given mainactivity oncreate() , onbackpressed()....

there no onresume().. facing same issue scenario2.

try change

from:

mainactivity.this.finish(); 

to

mainactivity.this.finishandremovetask();
