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

[Alex]

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

[Alex]

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)

[Alex]

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

contentResolver.takePersistableUriPermission(uri, FLAG_GRANT_READ_URI_PERMISSION)

[Alex]

then I load the video uri into the exoplayer by creating a MediaItem:

MediaItem.fromUri(videoUri)

and set it on the player

[Alex]

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?
