clearing activity stack android

Question

hi i've read many posts on stackoverflow on the subject but i still am not able to solve the problem. i need to clear my activity stack but the following comand doest work:

intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

i also tried the following for api 15 android4.0.3

intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);

noting seems to work.

here's the full method code

@Override
    public void onBackPressed() {
        super.onBackPressed();

        Intent intent = new Intent(this, FiltriAnagraficaPagina.class);
        intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
        startActivity(intent);
    }

this may help you

intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 
intent.addCategory(Intent.CATEGORY_HOME);

ya i read it. (i was looking for that qustion also), but it still leaves me with the same problem. is there a way i can solve this with the androidmanifest.xml? – Pheonix7 Apr 05 '12 at 13:03
ok. i have say 2 activities A,B. A requests a webservie/db for data and activity B shows it. then when i press back i want to go back to activity A to make a new request. but what happens is that activity 2 is still running so when activity A does the request and wants to put the data in activity B it cant because it is already full. understand? – Pheonix7 Apr 05 '12 at 13:09
ok then you have two ways to implement this first finish a as you call b and in backpress of b call a with new data (2) use setresult – vipin Apr 05 '12 at 13:12

Override onKeyDown() method instead of onBackPressed() in your Activity

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {


    if (keyCode == KeyEvent.KEYCODE_BACK) {

       Intent intent = new Intent(this, FiltriAnagraficaPagina.class);
           intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
           startActivity(intent);
        return true;
        }
     return super.onKeyDown(keyCode, event);
}
