/storage/emulated/0/uumoo/pocket/profile_pic.png：打开失败：ENOENT（没有那个文件或目录）

Question

我正在使用下面的代码从内部存储卡中读取图像，但我不断收到上述标题异常

public static byte[] convertFileToByteArray(String path) {
    File f = new File(path);

    byte[] byteArray = null;
    try {
        InputStream inputStream = new FileInputStream(f);
        ByteArrayOutputStream bos = new ByteArrayOutputStream();
        byte[] b = new byte[1024 * 8];
        int bytesRead = 0;

        while ((bytesRead = inputStream.read(b)) != -1) {
            bos.write(b, 0, bytesRead);
        }

        byteArray = bos.toByteArray();
    } catch (IOException e) {
        e.printStackTrace();
        Log.e(TAG,"e :"+e.getMessage());
    }
    return byteArray;
}

但图像文件已经在该目录中。我是不是错过了什么。 波纹管代码是保存过程。我正在使用 camera2 api 是否应该将图像转换为位图然后另存为文件？？

file = new File(Environment.getExternalStorageDirectory() +  
ImageManager.PIC_FILE_NAME );
        if (file.exists()) {
            file.delete();
        }
        ImageReader.OnImageAvailableListener readerListener = new ImageReader.OnImageAvailableListener() {
            @Override
            public void onImageAvailable(ImageReader imageReader) {
                Image image = null;
                try {
                    image = reader.acquireLatestImage();
                    ByteBuffer buffer = image.getPlanes()[0].getBuffer();
                    byte[] bytes = new byte[buffer.capacity()];
                    buffer.get(bytes);
                    save(bytes);

                } catch (FileNotFoundException e) {
                    e.printStackTrace();
                } catch (IOException e) {
                    e.printStackTrace();
                } finally {
                    {
                        if (image != null)
                            image.close();
                    }
                }
            }

            private void save(byte[] bytes) throws IOException {
                OutputStream outputStream = null;
                try {
                    outputStream = new FileOutputStream(file);
                    outputStream.write(bytes);
                } finally {
                    if (outputStream != null)
                        outputStream.close();
                }
            }

        };
