Android CameraX-ImageCapture返回的ImageProxy无效

我使用CameraX拍摄图像，然后使用Firebase ML工具包识别文本

当我们拍摄照片时，CameraX从ImageCapture返回ImageProxy

imageCapture.takePicture(Executors.newSingleThreadExecutor(), new ImageCapture.OnImageCapturedListener() {
                @Override
                public void onCaptureSuccess(ImageProxy image, int rotationDegrees) {
                    super.onCaptureSuccess(image, rotationDegrees);

                    startTextRecognization(image, rotationDegrees);
                }

                @Override
                public void onError(@NonNull ImageCapture.ImageCaptureError imageCaptureError, @NonNull String message, @Nullable Throwable cause) {
                    super.onError(imageCaptureError, message, cause);

                }
            });

将该图像传递给Firebase-

public void startTextRecognizing(ImageProxy imageProxy, int rotationDegrees) {
    this.imageProxy = imageProxy;
    this.rotationDegrees = rotationDegrees;

    if (imageProxy == null || imageProxy.getImage() == null) {
        return;
    }

    Image mediaImage = imageProxy.getImage();
    FirebaseVisionImage firebaseVisionImage =
            FirebaseVisionImage.fromMediaImage(mediaImage, rotationDegrees);

    FirebaseVisionTextRecognizer detector = FirebaseVision.getInstance()
            .getOnDeviceTextRecognizer();

    Task<FirebaseVisionText> result =
            detector.processImage(firebaseVisionImage)
                    .addOnSuccessListener(new OnSuccessListener<FirebaseVisionText>() {
                        @Override
                        public void onSuccess(FirebaseVisionText firebaseVisionText) {
                            extractText(firebaseVisionText);
                        }
                    })
                    .addOnFailureListener(new OnFailureListener() {
                        @Override
                        public void onFailure(@NonNull Exception e) {
                            Log.d("*Rahul", "Text Recognization Failed");
                        }
                    });

    //result.getResult();

}

你能帮忙吗，我哪里做错了？ImageCapture返回的图像格式无效。

当您调用super.onCaptureSccessImages，rotationDegrees时，它会关闭图像，因此可以在文本识别方法之后移动图像，或者删除该行，稍后通过调用image.close自己关闭图像

离题-你在用什么？我在最新的库版本中找不到ImageCapture.OnImageCapturedListener类。您应该使用可用的最新版本，因为它仍在alpha中，而且核心api正在更改，尽管开发人员说，当时最新的alpha 10已接近beta版，因此核心api现在应该不会有太大更改。
