How to Use ImagePicker

private ImagePicker imagePicker;
   // init
   
        imagePicker = new ImagePicker(getActivity(), new ImageChooserListener() {
            @Override
            public void onImageChosen(final ChosenImage chosenImage) {
                getActivity().runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        filePath = chosenImage.getFileThumbnail();
                        Picasso.with(getActivity())
                                .load(new File(filePath))
                                .resizeDimen(R.dimen.profileIconSize, R.dimen.profileIconSize)
                                .into(profileImageView);
                    }
                });
            }

            @Override
            public void onError(final String reason) {
                getActivity().runOnUiThread(new Runnable() {
                    @Override
