图像选择器未从图库捕获图像

Question

我正在尝试从imageview中的图库中加载图像。该应用程序将一直工作到选择图像为止。当我从图库中选择图像时，我的应用程序停止响应，并且出现错误“请重新启动应用程序”。下面提到执行此操作的代码块。

@OnClick(R.id.loadImageButton)
    void onLoadImageButtonClick() {

        // Determine Uri of camera image to save.
        final File root = new File(Environment.getExternalStorageDirectory() + File.separator + "MyDir" + File.separator);
        root.mkdirs();
//        final String fname = Utils.getUniqueImageFilename();
//        final File sdImageMainDirectory = new File(root, fname);
//        uri = Uri.fromFile(sdImageMainDirectory);

        // Camera.
        final List<Intent> cameraIntents = new ArrayList<Intent>();
        final Intent captureIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
        final PackageManager packageManager = getPackageManager();
        final List<ResolveInfo> listCam = packageManager.queryIntentActivities(captureIntent, 0);
        for (ResolveInfo res : listCam) {
            final String packageName = res.activityInfo.packageName;
            final Intent intent = new Intent(captureIntent);
            intent.setComponent(new ComponentName(packageName, res.activityInfo.name));
            intent.setPackage(packageName);
            intent.putExtra(MediaStore.EXTRA_OUTPUT, uri);
            cameraIntents.add(intent);
        }

        // Filesystem.
        final Intent galleryIntent = new Intent();
        galleryIntent.setType("image/*");
        galleryIntent.setAction(Intent.ACTION_GET_CONTENT);
        galleryIntent.addCategory(Intent.CATEGORY_OPENABLE);

        // Chooser of filesystem options.
        final Intent chooserIntent = Intent.createChooser(galleryIntent, "Select Source");

        // Add the camera options.
        chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, cameraIntents.toArray(new Parcelable[cameraIntents.size()]));

        startActivityForResult(chooserIntent, YOUR_SELECT_PICTURE_REQUEST_CODE);

        loadPhotoFromGallery();

    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (resultCode == Activity.RESULT_OK) {
            if (requestCode == YOUR_SELECT_PICTURE_REQUEST_CODE) {

                final boolean isCamera;
                if (data == null) {
                    isCamera = true;
                } else {
                    final String action = data.getAction();
                    if (action == null) {
                        isCamera = false;
                    } else {
                        isCamera = action.equals(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
                    }
                }

                Uri selectedImageUri;
                if (isCamera) {
                    selectedImageUri = uri;
                } else {
                    selectedImageUri = data == null ? null : data.getData();
                }
            }
        }

    }

请帮助。
