当我拍照时，我的“错误”是toast直接显示，为什么没有创建文件？

Question

我正在问一个新问题，如果它已经存在，请原谅我一次又一次地搜索，但我没有找到任何东西。

我的代码在 API28 模拟器上完美运行，但一旦我在 API29 模拟器及更高版本上运行它，它就不起作用......

你能帮助我吗？

CameraUtils.java

public static File getNewFile() {
   
        File mediaStorageDir = new File(Environment.getExternalStoragePublicDirectory(
                Environment.DIRECTORY_PICTURES), "MyCameraApp");

        if (!mediaStorageDir.exists()) {
            if (!mediaStorageDir.mkdirs()) {
                Log.d("MyCameraApp", "Failed to create directory");
                return null;
            }
        }

        String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
        File mediaFile;

        mediaFile = new File(mediaStorageDir.getPath() + File.separator +
                    "IMG_"+ timeStamp + ".jpg");

        return mediaFile;
    }

CameraFragment.java 我只向您展示“btnTakePicture.setOnCLick ....

btnTakePicture.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                btnTakePicture.setEnabled(false);
                AnimUtils.animateBtnTakePhoto(btnTakePicture);

                File file = CameraUtils.getNewFile();

                ImageCapture.OutputFileOptions outputFileOptions =
                        new ImageCapture.OutputFileOptions.Builder(file).build();

                imageCapture.setTargetRotation(CameraUtils.getDisplayRotation(requireContext()));
                imageCapture.setFlashMode(flashMode);
                imageCapture.takePicture(outputFileOptions, ContextCompat.getMainExecutor(requireContext()),
                        new ImageCapture.OnImageSavedCallback() {
                            @RequiresApi(api = Build.VERSION_CODES.M)
                            @Override
                            public void onImageSaved(@NonNull ImageCapture.OutputFileResults outputFileResults) {
                                MediaScannerConnection.scanFile(requireContext(),
                                        new String[]{file.toString()}, null, null);

                                btnTakePicture.setEnabled(true);

                                switch (typeAction) {
                                    case CameraFragment.ACTION_MESSAGE:
                                        Intent intent = new Intent(requireContext(), PhotoMessageActivity.class);
                                        intent.putExtra(PhotoMessageActivity.IMG_URI, file.getPath());
                                        intent.putExtra(ChatActivity.UID, uidReceiver);
                                        startActivity(intent);
                                        break;
                                    case CameraFragment.ACTION_STATUS:
                                        startActivity(new Intent(requireContext(), AddNewStoryPhotoActivity.class)
                                        .putExtra("IMG_URI", file.getPath()));
                                        break;
                                    case CameraFragment.ACTION_UPDATE_PICTURE:
                                        CropImage.cropMiniatureFromFragment(Uri.fromFile(new File(file.getPath())),
                                                requireContext(), CameraFragment.this);
                                        break;
                                }
                            }

                            @Override
                            public void onError(@NonNull ImageCaptureException exception) {
                                btnTakePicture.setEnabled(true);
                                Toast.makeText(requireContext(), "Error taking photo", Toast.LENGTH_SHORT).show();
                            }
                        });
            }
        });

我的代码适用于 API 29 模拟器，但一旦我的代码在 API29 和 API30 模拟器上进行测试，它就不再适用。
