selecting image from gallery for the second time does no work and show a black screen

1) Select image from gallery and image view will be updated with the picture;

2) For the first attempt, it actually works, the picture I took is displayed properly.

3) I launch the gallery again and select picture, the app goes into a blank screen and nothing happens.

I've been logging my trace and for the second time, onActivityResult is not even called despite startActivityForResult() being called already.

Here's some snippets of the relevant code:

private ImageView groupImage;
private Uri selectedImage;
groupImage = (ImageView) rootView.findViewById(R.id.groupLogo);
groupImage.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
            startActivityForResult(intent, RESULT_LOAD_IMG);
        }
    });

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
try{
    if(requestCode == RESULT_LOAD_IMG && resultCode == Activity.RESULT_OK && data!=null){
         selectedImage = data.getData();

        groupImage.setImageBitmap(MediaStore.Images.Media.getBitmap(getActivity().getContentResolver(), selectedImage));

    }
}catch (Exception e){
    e.getStackTrace();
}
}

This line causes a trouble:

groupImage = (ImageView) rootView.findViewById(R.id.groupLogo);

In the onActivityResult function you override a previous reference to the groupImage, therefore on onClickListener is not assigned to your ImageView
