I need to get previous activity from the stack and update it. Currently when I use startActivity() on second activity, opens the first one but will create new one, and by clicking back button, opens the first one (the one which not updated). How can I solve this problem?

Activity A

startActivity(new Intent(this, SecondActivity.class));

Activity B

@Override
    public void onBackPressed() {
        super.onBackPressed();
        startActivity(new Intent(this, FirstActivity.class).putExtra("profile", mProfile));
        finish();
    }

You want to go `A --> B --> update A`? – codeMagic Sep 09 '15 at 13:44

startActivity(new Intent(this, FirstActivity.class).putExtra("profile", mProfile). setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)); – Sagar Zala Sep 09 '15 at 13:48
