I am trying to use CameraX API to fetch photo, but after I updated to new API version 1.0.0-alpha06 it started to crash on

CameraX.bindToLifecycle(...)

方法。

错误日志为：

我的代码是：

    private fun initCamera(reverseFacing: Boolean = false) {
        ...

        val previewConfig = PreviewConfig.Builder()
                .setTargetAspectRatio(AspectRatio.RATIO_4_3)
                .setLensFacing(lensFacing)
                .build()

        val preview = Preview(previewConfig)
        preview.setOnPreviewOutputUpdateListener { previewOutput ->
            val parent = binding.preview.parent as ViewGroup
            parent.removeView(binding.preview)
            parent.addView(binding.preview, 0)
            binding.preview.surfaceTexture = previewOutput.surfaceTexture
        }

        val captureConfig = ImageCaptureConfig.Builder()
                .setFlashMode(flashMode)
                .setLensFacing(lensFacing)
                .build()

        val capture = ImageCapture(captureConfig)

        binding.takeAPhoto.setOnClickListener {
            ...
            val imageFile = createTempFile(System.currentTimeMillis().toString(), ".jpg")
            capture.takePicture(imageFile, this, object : ImageCapture.OnImageSavedListener {
                override fun onImageSaved(file: File) {
                    ...
                }

                override fun onError(imageCaptureError: ImageCapture.ImageCaptureError, message: String, cause: Throwable?) {
                    ...
                }
            })
        }

        CameraX.bindToLifecycle(this, capture, preview)
    }

有人知道这次崩溃的原因吗？我在文档中看不到任何相关信息（此时，CameraX已经过时了）

Is anyone know what caused this crash? I cannot see any related information in documentation (which by this time is out of date for CameraX)

推荐答案

为@ a-local -没人，@stéphane-péchard和@yoonhok正确地指出了alpha-6版本库中的错误。回滚到alpha-05可以消除我的崩溃情况。

As @a-local-nobody, @stéphane-péchard and @yoonhok rightly said the bug in alpha-6 version of library. Roll back to alpha-05 also removed crashes in my case.
