file.getName() returns nothing

I need to get the name of a CSV file selected for the user, but the getName() method does not return any value.

This is the code

private void readCSV(Uri uri) {
    InputStream is;
    File file = null;

    try {
        if (uri.getScheme().equals("file")) {
            file = new File(uri.toString());
            Log.i("File selected: ", file.getName()); //file.getName() doesn't work 
            is = new FileInputStream(file);

Why does this not return the name of the file?

Edit 1

    private void readCSV(Uri uri) {
        InputStream is;
        File file;

        try {
                 /*This conditional is false*/
            if (uri.getScheme().equals("file")) {
                file = new File(uri.toString());
                Log.i("File selected: ", file.getName()); //file.getName() doesn't
                is = new FileInputStream(file);
            } else {
               /* this part is the one that runs */

               is = this.getContentResolver().openInputStream(uri);
               Log.i("File selected: ", uri.getLastPathSegment()); //i tried this, it returns me 5049 but it is not the name of the selected file
            }

Getting file names through the apachecommons io lib https://commons.apache.org/proper/commons-io/javadocs/api-2.5/org/apache/commons/io/FilenameUtils.html

String name = FileNameUtils.getName(uri.getPath());

uri.toString() will return the object reference but not the file path.

You should call uri.getPath()

Use 

new File(uri.getPath());

instead of

new File(uri.toString());

NOTE: uri.toString() returns a String in the format: "file:///mnt/sdcard/image.jpg", whereas uri.getPath() returns a String in the format: "/mnt/sdcard/image.jpg".

try this

 fileName = uri.getLastPathSegment();
