Document files (word, pdf, excel,...) are no longer returned from MediaStore.Files.getContentUri(&qu-CodePudding

This is what I did and it works in sdk 29, it will return all files regardless of type.

val uri = MediaStore.Files.getContentUri("external")
val projection = arrayOf(
                 MediaStore.Images.Media.DATA,
                 MediaStore.Files.FileColumns.MIME_TYPE,
             )
val cursor = this.contentResolver.query(
             uri,
             projection,
             null,
             null,
             MediaStore.Images.Media.DATE_ADDED   " DESC"
         )

But after forced to raise targetSdk to at least 30 (Playstore required), it only returns image/video/audio files, is there any way to solve this problem, or is there any other way to read all files (or at least document files)?

I found the problem, since Android 11 we distinguish between read media files and all files, so the app needs to be allowed to read all files see workaround here: How to access permission allow management of all file in android studio

After allow this permission, the above code will work!

This should be related to Android.permissions (READ/WRITE_EXTERNAL_STORAGE)
