Data between activity and fragment

Question

I have a fragment which shows a list of taken pictures, and allows me to take a new one by clicking a button; however, after taken a picture it goes to a PreviewActivity to accept or cancel the picture taken, and also add a description.

After that, I want to comeback to the fragment with the information. To clarify:

My fragment calls the cameras as below:

imgCamera.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent(
                        android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
                nameFile = UUID.randomUUID().toString().replaceAll("-", "");
                fileName = HelperFoto.createFile(HelperFoto.getTempFile() + date.replace(":", "_"), nameFile + ".jpg");
                intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File(fileName.toString())));
                startActivityForResult(intent, 2);
            }
        });

After that, I send the generated data to the PreviewActivity as below:

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == 2 && resultCode == Activity.RESULT_OK) {

        Intent startPreview = new Intent(getContext(), PreviewActivity.class);
        startPreview.putExtra("path", fileName.toString());
        startActivity(startPreview);

    }

    super.onActivityResult(requestCode, resultCode, data);

}

Therefore, in my PreviewActivity, I was able to retrieve all the necessary information; thus, I can't send it back to the fragment (I tried to use onBackPressed() without success).

Could someone help me?

To pass informations between activity and fragment you can Bundle objects

You can have an example of how to use it here : Send data from activity to fragment in android.

I tried that; however it is not calling the fragment! – Tarcisiofl May 12 '16 at 15:00
What do you mean ? In the activity you set your bundle as an argument to the Fragment, which retrieves it in the onCreate method. – Xema May 12 '16 at 15:06

if you want to load fragment again then you have to follow these steps

FragmentManager fragmentManager = getFragmentManager();
            FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
            HelloFragment hello = new HelloFragment();
            fragmentTransaction.add(R.id.fragment_container, hello, "HELLO");
            fragmentTransaction.commit();

That works; however, some features for the activity still visible. – Tarcisiofl May 12 '16 at 16:41
