Answer 1

The second time you start a Activity, the intent is received in a method called onNewIntent. You can set the intent for the activity at this time.

@Override
protected void onNewIntent(Intent intent) {
    super.onNewIntent(intent);
    setIntent(intent);
}

Answer 2

try this in your code

A--->>> to B Activty (Here A finished when B Activity is opened)

 Intent addIntent = new Intent(this, B_AboutActivity.class);
                  startActivity(addIntent);
                  finish();

Then press Back button open the A Activty finish the B activity

@Override
        public boolean onKeyDown(int keyCode, KeyEvent event) {
            if ((keyCode == KeyEvent.KEYCODE_BACK)) {

            Intent intent = new Intent(getApplicationContext(),A_Activty.class);
                intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
                intent.putExtra("EXIT", true);
                startActivity(intent);
                finish();


            }
            return super.onKeyDown(keyCode, event);
        }
