You can use startActivityforResult().

When starting the activity use. startActivityForResult(intent, requestCode);

Intent i = new Intent(Intent.ACTION_DIAL);
    String p = "tel:" + getString(R.string.phone_number);
    i.setData(Uri.parse(p));
    startActivityForResult(i, 0);

Method

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
}

will be called when activity will be returned.

You can override onBackPressed method to control the behaviour of Back button:

         @Override
    public void onBackPressed() {
         // code to go to Activity B.
    }
