Hello I am trying to implement a way to export my database to csv file. But I am receiving this error.

My code:

val intent = Intent(Intent.ACTION_VIEW)
val contentUri = FileProvider.getUriForFile(context, "${context.packageName}.fileprovider", file)
val mimeType = context.contentResolver.getType(contentUri)
intent.setDataAndType(contentUri, mimeType)
intent.flags = Intent.FLAG_GRANT_READ_URI_PERMISSION or Intent.FLAG_GRANT_WRITE_URI_PERMISSION

return intent

I have cloned the example project which is supposed to work, it gave the same error. Is there anything with IDE or project libraries?Example project

The answer is when this code runs it tries to open .csv file. But the emulator does not have that file reader I think. The code works on an actual device.
