Android: startActivityForResult() from Fragment loses Data on Callback onActivityResult

Question

Because showDialog() is decprecated, i have to use DialogFragments now to fix my Image Picker functionality.

I got the Code from here, it worked like a charm so far.

Now, to keep it simple I'll only show the necessery Codelines. First, after clicking a Button on Activity A to select an image with this a Dialog appears:

ImagePickerFragment ip= new ImagePickerFragment(); 
ip.show(getSupportFragmentManager(), "imagePicker");

The Fragment Code looks like this:

 public class ImagePickerFragment extends DialogFragment{

    public Dialog onCreateDialog(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);

        //.. creating an adapter

        return new AlertDialog.Builder(getActivity())
        .setTitle("select Image")
        .setAdapter(adapter, new DialogInterface.OnClickListener(){

            public void onClick(DialogInterface dialog, int which){

              if (which == 0){ // from camera
                Intent intent    = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                File file        = new File(Environment.getExternalStorageDirectory(),
                                    "picture_" + String.valueOf(System.currentTimeMillis()) + ".jpg");
                mImageCaptureUri = Uri.fromFile(file);

                intent.putExtra(MediaStore.EXTRA_OUTPUT, mImageCaptureUri);

                getActivity().startActivityForResult(intent, PICK_FROM_CAMERA);
              } 
              else{  // pick from file
                Intent intent = new Intent();

                intent.setType("image/*");
                intent.setAction(Intent.ACTION_GET_CONTENT);

                getActivity().startActivityForResult(Intent.createChooser(intent, "complete Action..."), PICK_FROM_FILE);
              }
           }

         }).create():
     }
}

Now, back in my Activity A the onActivityResult() Code looks like this:

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (resultCode != RESULT_OK) return;

    if (requestCode == PICK_FROM_FILE){
    mImageCaptureUri = data.getData();
    path = getRealPathFromURI(mImageCaptureUri); //from Gallery

    if (path == null)
    path = mImageCaptureUri.getPath(); //from File Manager
    } 
    else path = data.getData().getPath(); **// this is were the Code starts when picture was taken with camera and where the exceptions come from..**

    if(path != null){
        // do something with image
    }
}

This actually works perfect for the Image picked from the galery, but for some reason not for the picture taken by the camera. After the Camera loads i can take a photo and when i accept that photo for saving, the app crashes.

The requestCodes are correct, but i've found out that the Uri send back from the Intent's data is always null, even if i put it seperately in the intent (i.e. putExtra, bundle). I really wonder why it works for galery, though :-/

Maybe one of you guys know what i did wrong?

P.S: I'm sorry for my bad english.

Update: i was asked for the crash info.
