CSVREADER FILE NOT FOUND

Question

Good morning. I've been looking for a solution to my problem for a long time and I can't find it. I have reviewed and tried the similar solutions shown on Stackoverflow and they do not work with my application. What I am trying to do is import the data from a csv file that I have previously selected. Thanks in advance.

1.I have given permission on AndroidManifest to write and read.

<?xml version="1.0" encoding="utf-8"?>
 <manifest xmlns:android="http://schemas.android.com/apk/res/android"
     xmlns:tools="http://schemas.android.com/tools"
     package="com.example.serviciosus">
     <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
     <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

2. By selecting the ImportarServices menu item, I select the file to import. So far so good.

        public boolean onOptionsItemSelected(MenuItem item) {
     if (item.getItemId() == R.id.addMembers) {
            openDialogMember();
        } else if (item.getItemId() == R.id.addservices
        ) {
            Intent intent = new Intent(context, MainActivityServices.class);
            startActivity(intent);
        } else if (item.getItemId() == R.id.importServices) {
            if (checkSelfPermission(Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
                requestPermissions(new String[] {Manifest.permission.READ_EXTERNAL_STORAGE}, CHOOSE_FILE);
            } else {
                Intent getFile = new Intent(Intent.ACTION_GET_CONTENT);
                getFile.addCategory(Intent.CATEGORY_OPENABLE);
                getFile.setType("*/*");
                startActivityForResult(Intent.createChooser(getFile, "Services.csv"), CHOOSE_FILE);
            }
    {
   

3. I capture the Uri of the file and through onActivityResult, sending it to the method of reading and saving data importCSV().

        protected void onActivityResult(int requestCode, int resultCode, @Nullable final Intent data) {
   
        super.onActivityResult(requestCode, resultCode, data);
        Uri route = data.getData();
        if (route != null) {
   
            try {
                importCSV(route);
            } catch (IOException e) {
                e.printStackTrace();
            }
   
        }
   
    }
   

4. Method to save the data in the database.

    public void importCSV(Uri uri) throws IOException {
         File file = null;
         file = new File(uri.getPath());
   
         try {
   
     CSVReader reader = new CSVReader(new FileReader(file));
     groupDate=null;
     while (( groupDate = reader.readNext()) != null){
         String type=groupDate[0];
         String date=groupDate[1];
         String observations=groupDate[2];
         int idPersons=Integer.valueOf(array[3]);
   
         // basedate insert method
         servicios.insertServices(type,date,observations,idPersons);
     }
   
         }catch (IOException e){
     Toast.makeText(this, "File does not exist", Toast.LENGTH_SHORT).show();
         }
     }
   

This is where I have the problem or so I think. I used a Toast to see what file it shows me and it shows it fine, but then it throws me the "File does not exist" exception. And that's what I can't fix. I would appreciate your help.
