Android ACTION_IMAGE_CAPTURE意图在onActivityResult上返回null

Question

当我们开始onActivityResult意图为意图获取null时，我们面临将意图数据传递到ACTION_IMAGE_CAPTURE方法的问题

以下是启动相机活动并将数据传递到onActivityResult()

的代码

不知道什么是错的，请帮帮我

感谢adavnce

 public void takePicture()
    {
        File directory = new File(Environment.getExternalStorageDirectory() + "/AML_AttachmentImages" + "/");

        if (!directory.exists())
        {
            directory.mkdir();
        }

        int count = 0;
        if (directory != null)
        {
            File[] files = directory.listFiles();
            if (files != null)
            {
                count = files.length;
            }
        }
        count++;
        String imagePath = "AML_IMAGE_" + count + ".jpg";
        File file = new File(directory, imagePath);
        outputFileUri = Uri.fromFile(file);

        Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
        startActivityForResult(intent, TAKE_PHOTO_CODE);

    }

                        Log.i("TAG", "newuri   " + newuri);

                    }
                    c1.close();

                    break;

            }
        }
