Getting full file name with extension

I have a method that should return the file name and file size returned from the contentResolver based on a selected file URI, however at times the file that was chosen has no extension. I am looking for a way to get the full file name with its extension or a way to determine the file type somehow. Below is my method I currently have 

    //This is the intent which triggers the file choosing
    Intent fileIntent = new Intent(  );
    fileIntent.setType( "*/*" );
    fileIntent.setAction( Intent.ACTION_GET_CONTENT );
    fileIntent.putExtra( Intent.EXTRA_LOCAL_ONLY, true );
    startActivityForResult( fileIntent, REQUEST_CODE_FILE );

    //Method in onActivityResult
    Uri selectedFile = intent.getData();
    Cursor cursor = null;
    String fileName = null;
    int fileSize = 0;
    try {
        cursor = getContentResolver().query( selectedFile, null, null, null, null );
        cursor.moveToFirst();
        fileName = cursor.getString( cursor.getColumnIndex( OpenableColumns.DISPLAY_NAME ));
        fileSize = cursor.getInt( cursor.getColumnIndex( OpenableColumns.SIZE ) );
    }catch( Exception ex ){
        ex.printStackTrace();
    }finally {
        if( cursor != null ) {
            cursor.close();
        }
    }

OpenableColumns.DISPLAY_NAME does not have to be a filename.

or a way to determine the file type

Call getType() on the ContentResolver, supplying the Uri. This should return a valid MIME type for the Uri.
