CameraX ImageCapture 无效 URI 内容

Question

我在使用 CameraX 捕获图像时遇到问题，它在图库中输出的图像已损坏，并且我在日志中收到此错误，该错误似乎指向 URI 内容的错误：

 E  Couldn't take photo:

这是我拍照的代码：

private fun takePhoto(specPic: String, context: Context, controller: LifecycleCameraController, onPhotoTaken: (Uri) -> Unit){
val contentResolver = context.contentResolver
val contentValues = ContentValues().apply {
    val formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss")
    val current = LocalDateTime.now().format(formatter)
    put(MediaStore.MediaColumns.DISPLAY_NAME, specPic + "_$current")
    put(MediaStore.MediaColumns.MIME_TYPE, "image/jpeg")
    put(MediaStore.MediaColumns.RELATIVE_PATH, Environment.DIRECTORY_PICTURES)
}
val uri = contentResolver.insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, contentValues)

if (uri!= null) {
    // Create the output file option to store the captured image in MediaStore
    val outputFileOptions = OutputFileOptions.Builder(contentResolver, uri, contentValues).build()
    controller.takePicture(outputFileOptions, ContextCompat.getMainExecutor(context), object : ImageCapture.OnImageSavedCallback {
        override fun onImageSaved(outputFileResults: ImageCapture.OutputFileResults) {
            val savedUri = outputFileResults.savedUri

            if (savedUri != null) {
                onPhotoTaken(savedUri)
            }
        }
        override fun onError(exception: ImageCaptureException) {
            Log.e("Camera", "Couldn't take photo:", exception)
        }

    })
}

}

我通过改变解决了这个问题

val uri = contentResolver.insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, contentValues)

至

val uri = MediaStore.Images.Media.getContentUri(MediaStore.VOLUME_EXTERNAL_PRIMARY)
