Look for the one that says `application/pdf`, I think, and replace that with `text/csv` — OneCricketeer, Mar 01 '16 at 11:29

I think you may want to read the csv file. you could get the csv file path. So see the following.

public static void readCSV(File file) {
    BufferedReader reader = null;
    StringBuilder stringBuilder = new StringBuilder();
    try {
        InputStreamReader isr = new InputStreamReader(new FileInputStream(file));// your csv file
        reader = new BufferedReader(isr);
        String line = null; // every time read one line
        while ((line = reader.readLine()) != null) {
            stringBuilder.append(line);
            stringBuilder.append("\n");
        }
    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        try {
            reader.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
 }

The stringBuilder.toString() is your csv file's content. Sorry for my English.
