I ran into a problem when working with CameraX on the tutorial from the android documentation. I can't find a method createSurfaceProvider()

I am using these libraries: camerax_version = &quot;1.0.0-beta10&quot;

CODE:

  1. @Override
  2.     public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
  3.         super.onViewCreated(view, savedInstanceState);
  5.         previewView = view.findViewById(R.id.previewView);
  7.         ListenableFuture&lt;ProcessCameraProvider&gt; cameraProviderFuture =
  8.                 ProcessCameraProvider.getInstance(requireContext());
  10.         cameraProviderFuture.addListener(() -&gt; {
  11.             try {
  12.                 ProcessCameraProvider cameraProvider = cameraProviderFuture.get();
  13.                 bindPreview(cameraProvider);
  15.             } catch (InterruptedException | ExecutionException e) {
  17.             }
  18.         }, ContextCompat.getMainExecutor(requireContext()));
  19.     }
  21.     private void bindPreview(ProcessCameraProvider cameraProvider) {
  22.         Preview preview = new Preview.Builder().build();
  24.         imageCapture = new ImageCapture.Builder()
  25.                 .setCaptureMode(ImageCapture.CAPTURE_MODE_MINIMIZE_LATENCY)
  26.                 .build();
  28.         CameraSelector cameraSelector = new CameraSelector.Builder()
  29.                 .requireLensFacing(CameraSelector.LENS_FACING_BACK)
  30.                 .build();
  32.         Camera camera = cameraProvider.bindToLifecycle(
  33.                 ((LifecycleOwner) this),
  34.                 cameraSelector,
  35.                 preview,
  36.                 imageCapture);
  38.         preview.setSurfaceProvider(
  39.                 previewView.createSurfaceProvider(camera.getCameraInfo()));
  40.

刚刚按照最新的教程进行操作，遇到了相同的问题。
但是，如果你只是简单地调用预览 preview 的 surfaceProvider 属性，一切都会正常工作。

val preview = Preview.Builder()
.build()
.also {
it.setSurfaceProvider(viewFinder.surfaceProvider)
}

英文:

Just followed the latest tutorial and faced with same issue.
But if you simply call the property surfaceProvider of your preview everything will work.

> val preview = Preview.Builder()
> .build()
> .also {
> it.setSurfaceProvider(viewFinder.surfaceProvider)
> }

仅替换

  1. preview.setSurfaceProvider(previewView.createSurfaceProvider(camera.getCameraInfo()));

为

  1. preview.setSurfaceProvider(previewView.getSurfaceProvider());
英文:

Just replace

  1. preview.setSurfaceProvider(previewView.createSurfaceProvider(camera.getCameraInfo()));

with

  1. preview.setSurfaceProvider(previewView.getSurfaceProvider());

将 Gradle 依赖项更改为：
implementation "androidx.camera:camera-camera2:1.0.0-rc01"
应该可以正常工作。

英文:

Change the gradle dependency to this :
implementation "androidx.camera:camera-camera2:1.0.0-rc01"
It should work
