Hello,
Deleting is working good but I am getting error while renaming file.

You have to request permission firstly.

val uriList: List<Uri> = listOf( Uri.withAppendedPath( MediaStore.Video.Media.EXTERNAL_CONTENT_URI, fileModel._id ) ) val pi = MediaStore.createWriteRequest(context!!.contentResolver, uriList) val request = IntentSenderRequest.Builder(pi.intentSender).build() renameResult.launch(request)
