java - Intent.FLAG_ACTIVITY_CLEAR_TOP in SherlockActivity not serving the purpose -

the scenario :

i have 4 activities : a, b, c , homeactivity. a launcher activity. using actionbarsherlock, a,b , c have menu option in bar.

the flow :

 a-> b-> c --**on submit in c**--> homeactivity 

now when press back button on home activity, goes activity b after clicking submit in c , using

     intent intent = new intent(this, homeactivity.class);      intent.setflags(intent.flag_activity_clear_top );  //shouldn't clear a,b , c ??     //intent.addflags(intent.flag_activity_clear_top );     startactivity(intent);             finish(); 

but remain on homeactivity data submitted , started.

also if menu button pressed on a,b,c, homeactivity started , in case, have default behaviour of back button(i.e go activity in menu pressed)

any insights on how flag_activity_clear_top not serving purpose!

(p.s. : homeactivity not launcher activity)

i think finish home acitivity while go home activity -> activity a. when using clear top flag home activity should alive in stack. please make sure not finish home activity.

and put code onkeydown() method in home activity.

@override     public boolean onkeydown(int keycode, keyevent event) {         if (keycode == keyevent.keycode_back) {             log.e("onkeydown>>>>", "called>>>>>");             finish();         }         return super.onkeydown(keycode, event);     }

other way

edit:

try put above code activity a.

remove finish() method code below:

intent intent = new intent(this, homeactivity.class);      intent.setflags(intent.flag_activity_clear_top );  //shouldn't clear a,b , c ??     //intent.addflags(intent.flag_activity_clear_top );     startactivity(intent); 

and important thing don't finish activity launcher activity clear top method should in stack of activity remain present in device.

hope solve problem.
