Answer 1

Try the following answer working for me in both case start activity from notification and start an activity from parent activity.

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case android.R.id.home:
            Intent upIntent = NavUtils.getParentActivityIntent(this);
            if (NavUtils.shouldUpRecreateTask(this, upIntent) || isTaskRoot()) {
                TaskStackBuilder.create(this).addNextIntentWithParentStack(upIntent)
                        .startActivities();
            } else {
                finish();
            }
            return true;
        default:
            return super.onOptionsItemSelected(item);
    }
}
