我在 Android Studio 中使用带有三星 S10+ 的相机 2 拍摄和保存照片的过程中发现了一个错误。

安卓版本：11

内核版本：4.14。113-22340597

final CaptureRequest.Builder captureBuilder = cameraDevice.createCaptureRequest(CameraDevice.TEMPLATE_STILL_CAPTURE);
captureBuilder.addTarget(reader.getSurface());
captureBuilder.set(CaptureRequest.CONTROL_MODE, CameraMetadata.CONTROL_MODE_AUTO);

int rotation = getWindowManager().getDefaultDisplay().getRotation();
captureBuilder.set(CaptureRequest.JPEG_ORIENTATION, ORIENTATIONS.get(rotation));

Long tsLong = System.currentTimeMillis() / 1000;
String ts = tsLong.toString();

file = new File(Environment.DIRECTORY_DOWNLOADS, ts + ".jpg");

ImageReader.OnImageAvailableListener readerListener = new ImageReader.OnImageAvailableListener() {
  @Override
  public void onImageAvailable(ImageReader reader) {
    Image image = null;

    image = reader.acquireLatestImage();
    ByteBuffer buffer = image.getPlanes()[0].getBuffer();
    byte[] bytes = new byte[buffer.capacity()];
    buffer.get(bytes);
    try {
      save(bytes);
    } catch (IOException e) {
      e.printStackTrace();
    } finally {
      if (image != null) {
        image.close();
      }
    }
  }
};

而且...这是错误结果
