I have found the answer. "\n" is new line feed, "\r" is carriage return. "\n" = 10 in decimal; and "\r" = 13 in decimal. so I want 13 in decimal for Carriage return, "\r" worked for me instead of "\n". (Look at the ASCII table closer :))

String num = String.valueOf(number);
String cr =  String.valueOf(number_cr);
String s = num + "\n" + cr;

or you can try something like:

String eol = System.getProperty("line.separator");  
String s = num + eol + cr;

See How to insert a new line in strings in Android for more. Hope it helps.

  • I tried the two ways you suggested but it didnt work for me. String s to decimal 65 10 but I want 65 13 (13 is carriage return) – BioengineerDavid Aug 18 '13 at 11:13
  • i am trying both the methods and they seems to work. Check it yourself. Run the code here: http://rextester.com/live/ZLN61101 – Shobhit Puri Aug 18 '13 at 11:17
  • You can first try to convert those integers to string using `String.valueOf(number)` and then use them – Shobhit Puri Aug 18 '13 at 11:18

  • Great. You can post that as a new answer. This would help those who would come to this thread in future. Thanks :) – Shobhit Puri Aug 18 '13 at 11:38
