Can't open .xlsx file from aspose cells if it wasn't created using aspose cells - aspose-cells

Question

So I'm working on an app for android and I've gotten it to work as long as it's been created using aspose cells. Here is my code:
class Home: Fragment(R.layout.fragment_home) {
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
}
override fun onCreateView(
inflater: LayoutInflater,
container: ViewGroup?,
savedInstanceState: Bundle?
): View? {
val view: View = inflater.inflate(R.layout.fragment_home, container, false)
val load = view.findViewById<Button>(R.id.button3)
val new = view.findViewById<Button>(R.id.button4)
val editText = view.findViewById<EditText>(R.id.editTextTextPersonName)
new.setOnClickListener(View.OnClickListener {
Excel.name = "${Environment.getExternalStoragePublicDirectory(DIRECTORY_DOWNLOADS)}/${editText.text.toString()}.xlsx"
Excel.workbook = Workbook()
Excel.workbook!!.save(Excel.name)
println("Created: ${Excel.workbook}")
})
load.setOnClickListener(View.OnClickListener {
Excel.workbook = Workbook("${Environment.getExternalStoragePublicDirectory(DIRECTORY_DOWNLOADS)}/${editText.text.toString()}.xlsx")
Excel.name = "${Environment.getExternalStoragePublicDirectory(DIRECTORY_DOWNLOADS)}/${editText.text.toString()}.xlsx"
Excel.workbook!!.save("${Environment.getExternalStoragePublicDirectory(DIRECTORY_DOWNLOADS)}/${editText.text.toString()}.xlsx")
println("Loaded: ${Excel.workbook}")
})
return view
}
}
the problem is when I try to download a .xlsx file and load it, it gives me this error:
Caused by: java.io.FileNotFoundException: /storage/emulated/0/Download/ECR.xlsx: open failed: EACCES (Permission denied)
I'm not sure why this is happening. Any help would be awesome! Thanks!
