权限拒绝:读取 androidx.core.content.FileProvider 试图共享视频文件

我已经查看了几篇关于此的帖子,并且我尝试了六个建议的解决方案。我有一些与此几乎相同的工作,而不会在我编写的另一个应用程序中引发异常,但我无法让它不引发异常,尽管文件确实被传输了!正在设置权限并且文件确实传输得很好,但尽管不会使应用程序崩溃,但仍会抛出异常。

我拥有的是这个:

fun shareVideo(videoFile: File, context: Context) {
  if(videoFile.exists()) {
    Timber.i("Video file exists and the length in bytes is: ${videoFile.length()}")
  } else {
    Timber.w("Video file does not exist. Exiting.")
    return
  }

  val uris = arrayListOf<Uri>()
  val uri = FileProvider.getUriForFile(context.applicationContext, context.packageName + ".provider", videoFile)

  Timber.i("Uri: $uri + path: ${uri.path}")

  uris.add(uri)

  val intent = Intent()
  intent.action = Intent.ACTION_SEND_MULTIPLE
  intent.putExtra(Intent.EXTRA_SUBJECT, "Shared files")
  intent.type = "video/mp4"
  intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true)
  intent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris)
  intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION)
  intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)

  Timber.i("Intent: $intent")

  try{
      ContextCompat.startActivity(context, Intent.createChooser(intent, "Shared Videos"), null)
  } catch (e: Exception) {
    Timber.e("Exception starting activity. \nException was ${e.message}\n Stack trace to follow:\n ${e.stackTrace}")
  }
}

堆栈跟踪如下所示:

2021-03-07 14:21:59.570 6039-6207/com.company.app E/DatabaseUtils: Writing exception to parcel
java.lang.SecurityException: Permission Denial: reading androidx.core.content.FileProvider uri content://com.company.app.provider/external_files/1615148514218.mp4 from pid=32136, uid=1000 requires the provider be exported, or grantUriPermission()

Timber 日志输出如下所示:

所以文件在那里,我在附件中看到它确实添加了它,我确实通过电子邮件/等获取了它。并且可以查看,但是日志中抛出异常。

我的 provider_paths.xml 文件如下所示:

<?xml version="1.0" encoding="utf-8"?>
<paths>
  <cache-path          name="cache"          path="/"/>
  <external-cache-path name="external_cache" path="." />
  <external-path       name="external"       path="." />
  <external-files-path name="external_files" path="." />
  <files-path          name="app_videos"     path="." />
</paths>

我的清单中有这个:

        <provider
          android:name="androidx.core.content.FileProvider"
          android:authorities="${applicationId}.provider"
          android:exported="false"
          android:grantUriPermissions="true">
          <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/provider_paths" />
        </provider>

一切看起来都与我的应用程序完全一样,但这个应用程序会引发异常。

有人能看出我在做什么吗?
