I am having trouble with ExoPlayer playing an internal video from the downloads folder, SecurityPermissions all around. Code in :thread:

The exact error:
```Caused by: java.lang.SecurityException: Permission Denial: reading com.android.providers.downloads.DownloadStorageProvider uri <content://com.android.providers.downloads.documents/document/raw:/storage/emulated/0/Download/kitty.mp4> from pid=20754, uid=10171 requires that you obtain access using ACTION_OPEN_DOCUMENT or related APIs```

I use the `OpenDocument()`  activity result listener and set the following flags on the intent:

```addFlags(FLAG_GRANT_PERSISTABLE_URI_PERMISSION)
addFlags(FLAG_GRANT_READ_URI_PERMISSION)```

When receiving a result I set the following on the `contentResolver` to receive a lasting permission:

```contentResolver.takePersistableUriPermission(uri, FLAG_GRANT_READ_URI_PERMISSION)```

then I load the video uri into the exoplayer by creating a MediaItem:
```MediaItem.fromUri(videoUri)```
and set it on the player

I tried the same with `getContent()` as an `ActivityResultListener` but that didn't help.. I suspect the exoplayer starting a player thread with a non-permission enabled `contentResolver` or something to that effect but I cannot put my finger on it yet. Did someone use SAF with ExoPlayer and can help me out here?
