A estrutura do aplicativo é assim:

tabHost (in Activity) -> contains -> TabFragment(extend base container fragment)

1. O código na Atividade:

tabHost.addTab(
                tabHost.newTabSpec("home").setIndicator("",
                        getResources().getDrawable(R.drawable.btn_home)),
                HomeFragment.class, null);

2. O código no HomeFragment (Observe que HomeFragment não é a função real, mas um contêiner como este e estende BaseContainerFragment):

public class HomeFragment extends BaseContainerFragment {

    public Home homeFrag;
    private boolean mIsViewInited;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        return inflater.inflate(R.layout.container_fragment, null);
    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        if (!mIsViewInited) {
            mIsViewInited = true;
            initView();
        }
    }

    private void initView() {
        homeFrag = new Home();
        replaceFragment(homeFrag, false);
    }

}

3. BaseContainerFragment

public class BaseContainerFragment extends Fragment {

    public void replaceFragment(Fragment fragment, boolean addToBackStack) {
        FragmentTransaction transaction = getChildFragmentManager().beginTransaction();
        if (addToBackStack) {
            transaction.addToBackStack(null);
        }
        transaction.replace(R.id.container_framelayout, fragment);
        transaction.commit();
    }

    public boolean popFragment() {
        boolean isPop = false;
        if (getChildFragmentManager().getBackStackEntryCount() > 0) {
            isPop = true;
            getChildFragmentManager().popBackStack();
        }
        return isPop;
    }

}

4. Na Casa (O conteúdo real do fragmento)

UploadType fragment = new UploadType();
                    Bundle bundle = new Bundle();
                    bundle.putString("form_type", "request");
                    fragment.setArguments(bundle);
                    ((BaseContainerFragment)getParentFragment()).replaceFragment(fragment, true);

5. E no UploadType, eu chamo a atividade de câmera, mas onActivityResult é apenas retorno na atividade principal.

startActivityForResult(intent, REQUEST_CAMERA);

public void onActivityResult(int requestCode, int resultCode, Intent data) {
        Log.d("test1", "result2");
        super.onActivityResult(requestCode, resultCode, data);
}

Como posso acionar o onActivityResult em UploadType? Obrigado pela ajuda.
