Android开发实现调用相本图片并裁剪上传功能

Android开发实现调用相册图片并裁剪上传功能
该功能用到了Apache的开源项目simplecropimage.
下面代码中CropImage类为SimpleCropImage中的类，该类需要在Manifest中进行注册。simplecropimage用到的依赖类在附件中。
直接上代码：

    /** 打开相册(第一步)*/
    private static final String IMAGE_UNSPECIFIED = "image/*";

    private void openPhotos() {
        Intent intent = new Intent(Intent.ACTION_PICK);
//        intent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
        intent.setFlags(Intent.FLAG_ACTIVITY_BROUGHT_TO_FRONT);
        intent.setDataAndType(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, IMAGE_UNSPECIFIED);
        startActivityForResult(intent, REQUEST_PHOTOS);
    }

   @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {

        switch (requestCode) {
            case REQUEST_CUTRESULT:
                dealCutResult(resultCode, data);
                break;
            case REQUEST_PHOTOS:
                dealPhotosResult(resultCode, data);
                break;
        }

    private void dealPhotosResult(int resultCode, Intent data) {
        if (Activity.RESULT_OK == resultCode) {
            if (data != null) {
                // 从相册获取照片uri
                startPhotoCut(data.getData());
            }
        } else {
            if(GlobleParams.isEnglish){
               shortToast("Upload canceled");
            }else{
               shortToast("您已经取消了上传操作");
            }
        }
    }

    /**开始裁剪(第二步)*/
    public void startPhotoCut(Uri uri) {
        String realPathFromURI = getRealPathFromURI(uri);
        if(realPathFromURI == null){
            return;
        }
        File file = new File(realPathFromURI);
        Intent intent = new Intent(App.getInstance(), CropImage.class);

        // tell CropImage activity to look for image to crop
        intent.putExtra(CropImage.IMAGE_PATH, file.getAbsolutePath());

        // allow CropImage activity to rescale image
        intent.putExtra(CropImage.SCALE, true);

        // if the aspect ratio is fixed to ratio 3/2
        intent.putExtra(CropImage.ASPECT_X, 0);
        intent.putExtra(CropImage.ASPECT_Y, 0);

        // start activity CropImage with certain request code and listen
        // for result
        startActivityForResult(intent, REQUEST_CUTRESULT);
    }
  private void dealCutResult(int resultCode, Intent data) {
        if (resultCode == Activity.RESULT_OK) {
            String path = data.getStringExtra(CropImage.IMAGE_PATH);
            // if nothing received
            if (path == null) {return;}
            uploadPhoto(path);

        } else {

            }else{
                shortToast("您已经取消了上传操作");
            }
