Answer 1

I know this is a really old question but I wanted to put in a valid solution, use onNewIntent() and treat it as onActivityResult().

In activity D you would structure your intent as

Intent intent = new Intent(yourContext, Activity_A.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.putExtra("someName", data);
startActivity(intent);
finish();

and then in Activity_A

@Override
protected void onNewIntent(Intent intent) {
    super.onNewIntent(intent);
    // update your UI
    intent.getSerializableExtra(...
}
