Android 改型2的作用域存储视频上载问题（java.io.FileNotFoundException:打开失败：eNot（无此类文件或目录）

我想上传视频使用改型在API级别Q和更高

我创建了一个媒体助手，它给我一个图像和视频文件列表

return if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
    val collectionWithPending = MediaStore.setIncludePending(collection)
    CursorLoader(context, collectionWithPending, projection, selection, null, sortOrder)
} else {
    CursorLoader(context, collection, projection, selection, null, sortOrder)
}

媒体加载工作正常：openFileDescriptor

           image.context.contentResolver.openFileDescriptor(mData.contentUri!!, FILE_OPEN_READ_MODE).use {
            image.setPicture(mData.contentUri, RequestOptions().placeholder(R.color.white).error(R.color.white).diskCacheStrategy(DiskCacheStrategy.NONE))
        }

我尝试过两种不同的方法：

路径：/storage/emulated/0/Pictures/1568101688613.jpg。它给了我一个错误拒绝开放访问

内容uri为：content://media/external/video/media/78。它给了我一个错误java.io.FileNotFoundException:content:/media/external/video/media/78:open失败：enoint（没有这样的文件或目录）

我正在使用改型上传视频

inline fun <reified T : Any>getRetrofit(): T {
val retrofit = Retrofit.Builder()
    .client(getDefaultClient())
    .baseUrl(BASE_URL)
    .addConverterFactory(getCustomConverterFactory())
    .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
    .build()

return retrofit.create(T::class.java)}

//Api call Interface
interface UploadImagesRetrofitService {
    @Multipart
    @POST(MEDIA)
    fun getUploadMedia(
        @Header(ID) xID: String? = null,
        @Header(MEDIA_TYPE) mediaType: String? = null,
        @Header(UPLOAD_TYPE) uploadType: String? = null,
        @Part files: MultipartBody.Part
    ): Observable<UploadMediaResponse>
}

//Access the Interface
fun getMediaUpload(xID: String, mediaType: String, uploadType: String, files: MultipartBody.Part): Observable<UploadMediaResponse> {
    return getRetrofitServiceTTU<UploadImagesRetrofitService>().getUploadMedia(xID, mediaType, uploadType, files)
}

 fun getUpload(xID: String, mediaType: String, uploadType: String, files: MultipartBody.Part, height: Int = 0, width: Int = 0) {

    addDisposable(repo.getMediaUpload(xID, mediaType, uploadType, files).subscribeOn(Schedulers.io()).observeOn(Schedulers.io()).subscribe({
        if (it != null && it.reponseCode == 0) {
            it.height = height
            it.width = width
            it.mediaType = mMediaType
            mUploadingInterFace.getSuccessResponse(it)
        } else {
            mUploadingInterFace.getErrorResponse(it.responseError)
        }
    }, { thr ->
        thr.printStackTrace()
        if ((mContext?.isValid() == true) && mContext is BaseActivity) mContext.showError(mContext.getString(R.string.error_upload_media))
    }))
}
