You've provided a nice Intent builder for starting Activities. One could use it like this:

MyActivity_.intent(getActivity()).startForResult(REQUEST_SEARCH);

However, if this is called from a Fragment, after the started Activity returns to this caller Fragment, onActivityResult will not get called! The generated code for startForResult looks like this:

public void startForResult(int requestCode) {
    if (context_ instanceof Activity) {
        ((Activity) context_).startActivityForResult(intent_, requestCode);
    } else {
        context_.startActivity(intent_);
    }
}

And this is the culprit. In this case the Activity version of startActivityForResult is called, not the Fragment version.
