Yup, great formatting. And you can -- and probably should -- definitely call startActivityForResult() from each of Activity A, B, and C (and don't finish() right away). In B and C you can check for a successful result and finish(), passing the result on back to A.

    @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if((resultCode == RESULT_OK) && (requestCode == MY_RESULT_CODE)) {
        setResult(RESULT_OK, data);
        finish();
    }
}

If you want B and C to disappear regardless, do the following instead:

    @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    setResult(resultCode, data);
    finish();
}
