window leaked on Tablet

[exiomsphpteam]

Hey,
I am having Window leaked exception after selecting images.
Please help.

My Code is

 Intent intent1 = new Intent(getActivity(), ImagePickActivity.class);
                intent1.putExtra(IS_NEED_CAMERA, true);
                intent1.putExtra(Constant.MAX_NUMBER, 5);
                startActivityForResult(intent1, CAMERA_PERMISSION_REQUEST_CODE);``

 case CAMERA_PERMISSION_REQUEST_CODE:
                if (resultCode == RESULT_OK) {
                    if (data != null) {
                        try {
                            ArrayList<ImageFile> list = data.getParcelableArrayListExtra(Constant.RESULT_PICK_IMAGE);
                   /* imagePath.clear();
                    imagePath = data.getStringArrayListExtra(SelectorSettings.SELECTOR_RESULTS);*/

                            for (ImageFile files : list) {
                                String extension = "";
                                String uploadedFileName = files.getPath();
                                if (null != uploadedFileName) {
                                    extension = uploadedFileName.substring(uploadedFileName.lastIndexOf("."));
                                }
                                File file = new File(uploadedFileName);
                                File attachment = new File(file.getAbsolutePath());
                                if (attachment.exists()) {
                                    FileInputStream fileInputStreamReader = null;
                                    try {
                                        fileInputStreamReader = new FileInputStream(attachment.getAbsolutePath());
                                    } catch (FileNotFoundException e) {
                                        e.printStackTrace();
                                    }

                                    byte[] bytes = new byte[(int) attachment.length()];
                                    try {
                                        int read = fileInputStreamReader.read(bytes);
                                    } catch (IOException e) {
                                        e.printStackTrace();
                                    }
                                    String attachment_base64 = Base64.encodeToString(bytes, Base64.DEFAULT);

                                    attachedPhotosList.add(new AttachedFileModule(attachment_base64, file.getName(), file.getAbsolutePath(), extension));
                                }

                            }
                            if (attachedPhotosList.size() > 0) {
                                btnUploadPhoto.setVisibility(View.VISIBLE);
                                setImageAdapter();
                            }

                        } catch (NullPointerException e) {
                            e.printStackTrace();
                        }

                    }

                }
                break;
