My HTTP Request responds with combination of string and JSON, something like this:

null{"username:name","email:email"}

I need only the JSON part.

I directly tried parsing as json object, which was not right of course. I tried splitting it: serverResponse.split("{"), but android does not allow to parse with this character because it is not a pattern. Any suggestion how i can achieve this?

String.split uses regular expressions, and since '{' is a special character in regular expressions, you should escape it like this: serverResponse.split("\\{").

It would be better to change the server side, but you can also just use split. The only thing you need to do is escape your {.

String json = serverResponse.split("\\{")[1];

  • I also don't know why the server side sends null because it is not handled by me. I just had to get json and parse it. Thank you for the helpful reply. – user3303274 Nov 10 '15 at 12:55
  • Probably the server sends JSONP, which is used for javascript, the null is actually the `callback` variable. Try to get the url like: `http:yoururl.com/?callback=` to see if that gives you an empty string in front. – Niki van Stein Nov 10 '15 at 12:57

It is a bad idea and a bad practice to split a Json. If one day it you change on the serve side, it may pick a wrong part of your Json Object. I recommend you to PARSE it, even if it is simple and small.
